Caution 1: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is
operated over the absolute maximum ratings.
Caution 2: Should by any chance the maximum junction temperature rating be exceeded the rise in temperature of the chip may result in deterioration of the
properties of the chip. In case of exceeding this absolute maximum rating, design a PCB with thermal resistance taken into consideration by
increasing board size and copper area so as not to exceed the maximum junction temperature rating.

(Note 3) Relative to GND2
(Note 4) Should not exceed Tj = 150 C

Description of Pins and Cautions on Layout of Board
1. V_BATT (Main power supply pin)
This is the main power supply pin. Connect a bypass capacitor between the V_BATT pin and the GND1 pin in order to
suppress voltage variations.
2. VREG1 (Input-side internal power supply pin)
This is the internal power supply pin on the input-side. Be sure to connect a bypass capacitor between the VREG1 pin
and the GND1 pin in order to prevent oscillation and suppress voltage variation due to the driving current of the internal
transformer.
3. GND1 (Input-side ground pin)
This pin is the ground pin on the input-side.
4. VCC2 (Output-side power supply pin)
This is the power supply pin on the output-side. To reduce voltage fluctuations due to the output current, connect a
bypass capacitor between the VCC2 pin and the GND2 pin.
5. VREG2 (Output-side internal power supply pin)
This is the internal power supply pin on the output-side. Be sure to connect a bypass capacitor between the VREG2 pin
and the GND2 pin in order to prevent oscillation and suppress voltage variation due to the driving current of the internal
transformer.
6. GND2 (Output-side ground pin)
This is the ground pin on the output-side. Connect the GND2 pin to the emitter/source of output device.
7. INA, INB (Control input pin), GRSEL (Gate resistance switching pin)
These are pins for determining the output logic. The OUT1F pin holds the previous state after GRSEL is switched and
until the next the OUT1 pin is switched.

8. FLT (Fault output pin)
The FLT pin is an open drain pin that sends a fault signal when a fault occurs (i.e., when the under voltage lockout
function (UVLO) or short circuit protection function (SCP) is activated).
State

L
While in normal operation
When a Fault occurs (UVLO/SCP)
9. OSFB (Output pin for monitoring gate condition)
The OSFB pin is an open drain pin that outputs L when the gate theory of output element being monitored by the
PROOUT1 pin is H. However, the OSFB pin becomes Hi-Z when a fault occurs (i.e., when the under voltage lockout
function (UVLO) or short circuit protection function (SCP) is activated).

the switching controller is not used, connect it to the GND1 pin.
13. FET_G (MOS FET for transformer drive control pin for switching controller)
This is a MOS FET for transformer drive control pin for switching controller. Leave it open when the switching controller
is not used.
14. SENSE (Current feedback resistor connection pin for switching controller)
This is a pin connected to the resistor of the switching controller current feedback. This pin combines with current
detection at overcurrent restriction function for switching controller. When overcurrent restriction is activated, switching
controller will be at OFF state (the FET_G pin outputs Low), and the overcurrent restriction function will be released in
the next switching period. When the switching controller is not used, connect it to the VREG1 pin.
15. OUT1, OUT1F (Output pin)
The OUT1 pin and the OUT1F pin are gate driving pins.
16. OUT2 (Miller clamp pin)
This is the miller clamp pin for preventing a rise of gate voltage due to miller current of output element. It also functions
as a pin for monitoring gate voltage for miller clamp and the OUT2 pin voltage become not more than VOUT2ON (Typ 2.0 V),
miller clamp function operates. The OUT2 pin should be connect to the GND2 pin when miller clamp function is not
used.
17. PROOUT1 (Soft turn off pin for short circuit protection / Gate voltage input pin), PROOUT2 (Fast turn off pin for short
circuit protection)
They are pins for soft turn off of output element when short-circuit protection is activated. Both the PROOUT1 pin and
the PROOUT2 pin turn on for tPRO2ON from short circuit detection. After tPRO2ON, only the PROOUT1 pin turns on.
Leave the PROOUT2 pin open when the fast turn off function is not used. It also functions as the PROOUT1 pin for
monitoring gate voltage for output state feedback function.
18. SCPIN (Short circuit detection pin), SCPTH (Short circuit detection threshold setting pin)
The SCPIN pin and the SCPTH pin are current detection pins for short circuit protection. When the SCPIN pin voltage
becomes the SCPTH pin voltage, or more, the short circuit protection function is activated. Built-in MOSFET between
the SCPIN pin and the GND2 pin for discharging electric charge of external filter when the OUT1 pin is L state. In the
open state, the IC may possibly malfunction. To avoid this risk, apply voltage to SCPTH pin even when not using the
short circuit protection function and connect the SCPIN pin to the GND2 pin.
19. TCOMP (Temperature compensation pin of short circuit detection voltage)
The TCOMP pin connects a resistor that sets the SCPIN pin output current according to TO pin voltage.
20. TC (Resistor connection pin for setting constant current)
The TC pin is a resistor connection for setting the constant current output. If an arbitrary resistance value is connected
between the TC pin and the GND2 pin, it is possible to set the constant current value output from the TO1 pin.
21. TO (Constant current output / sensor voltage input pin)
The TO pin is constant current output / voltage input pins. It can be used as a sensor input by connecting an element
with arbitrary impedance between the TO pin and the GND2 pin.
Description of Functions and Examples of Constant Setting
1. Fault Status Output
This function is used to set a fault signal from the FLT pin when a fault occurs (i.e., when the under voltage lockout
function (UVLO) or short circuit protection function (SCP) is activated) and hold the fault signal until fault output holding
time (tFLTRLS) is completed.

2. Under Voltage Lockout (UVLO) Function
The BM60060FV-C incorporates the under voltage lockout (UVLO) function on V_BATT, VCC2, VREG1 and VREG2.
When the power supply voltage drops to the UVLO ON voltage, the OUT1 pin and the FLT pin will both output the “L”
signal and the OUT1F pin becomes the "Hi-Z" state. However, if V_BATT or VREG1 voltage drops to the UVLO ON
voltage when the OUT1F pin is "L", the OUT1F pin holds "L" state. When the power supply voltage rises to the UVLO
OFF voltage, UVLO will be reset after the fault output holding time tFLTRLS is completed. However, if the INA pin is "L" or
the INB pin is "H", when UVLO reset timing, the OUT1F pin holds the previous state until the next the OUT1 pin is
switched even if the GRSEL pin is H. In addition, to prevent malfunction due to noise, filtering time are set on both
V_BATT, VCC2, VREG1 and VREG2.

3. Short Circuit Protection (SCP) Function
Continuing the state where the SCPIN pin voltage ≥ the SCPTH pin voltage for tDSCPPRO or more, the short circuit
protection function is activated. Once the function is activated, the OUT1 pin and the OUT1F pin become "Hi-Z" state
and both the PROOUT1 pin and the PROOUT2 pin turn on (Fast Turn Off). After tPRO2ON since the short circuit
detection, the PROOUT2 pin turns off (Soft Turn Off). Furthermore, when the SCPIN pin voltage < the SCPTH pin
voltage and the OUT2 pin voltage < VOUT2ON, the OUT1 pin and the OUT2 pin become L. In additional, the FLT pin
becomes L after tDSCPFLT since the short circuit protection function is activated. Finally, when the fault output holding
time tFLTRLS is completed, the SCP function will be released and the FLT pin becomes "Hi-Z". The PROOUT1 pin hold L
state until the OUT1 pin becomes H.
This IC has a built-in temperature characteristics correction function for short circuit detection voltage. Since the SCPIN
pin outputs current ISCPIN according to the TO pin voltage, the IC is capable of correcting the temperature characteristics
for short circuit detection voltage using voltage drop of resistor RSCPCOMP connected to the SCPIN pin in series. The
SCPIN pin output current ISCPIN can be formulated as:
ISCPIN [mA] = VTO [V] /RTCOMP [kΩ]
Therefore, short circuit detection voltage VSC can be formulated as:
VSC [V] = VSCPTH [V] - VTO [V] × RSCPCOMP [kΩ] / RTCOMP [kΩ]
Still more, built-in MOSFET between the SCPIN pin and the GND2 pin for discharging electric charge of external filter
when OUT1 is L state. This MOSFET turns off after tSCPLEB since the OUT1 pin becomes H. And this MOSFET
immediately turns on after the OUT1 pin becomes L. Also, this MOSFET immediately turns on after short circuit
detection.

7. Switching Controller
(1) Basic action
This IC has a built-in switching controller which repeats ON/OFF synchronizing with internal clock. When V_BATT
voltage is supplied (VBATT > VUVLOBATTH and VREG1 > VUVLOREG1), the FET_G pin starts switching by soft-start. Output
voltage is determined by the following equation by external resistance and winding ratio “n” of flyback transformer (n =
VOUT2 side winding number/VOUT1 side winding number)
VOUT = VFB×{(R1+R2)/R2} ×n [V]
(2) MAX DUTY
When, for example, output load is large, and voltage level of the SENSE pin does not reach current detection level,
output is forcibly turned OFF by Maximum On Duty (DONMAX).
(3) Over voltage protection function, under voltage protection function
The switching controller has protection function as overvoltage protection (OVP) and under voltage protection (UVP).
OVP and UVP monitor the voltage of the FB pin. When the protection function is activated, switching controller will
be OFF state (the FET_G pin outputs Low). The switching controller protection holding time (tDCDCRLS) is completed,
the protection function will be released. Under voltage function is not activated during soft-start.

Operational Notes
1.
2.
Reverse Connection of Power Supply
Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when
connecting the power supply, such as mounting an external diode between the power supply and the IC’s power
supply pins.
Power Supply Lines
Design the PCB layout pattern to provide low impedance supply lines. Furthermore, connect a capacitor to ground
at all power supply pins. Consider the effect of temperature and aging on the capacitance value when using
electrolytic capacitors.
3.
4.
Ground Voltage
Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition.
Ground Wiring Pattern
When using both small-signal and large-current ground traces, the two ground traces should be routed separately but
connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal
ground caused by large currents. Also ensure that the ground traces of external components do not cause
variations on the ground voltage. The ground lines must be as short and thick as possible to reduce line impedance.
5.
6.
Recommended Operating Conditions
The function and operation of the IC are guaranteed within the range specified by the recommended operating
conditions. The characteristic values are guaranteed only under the conditions of each item specified by the
electrical characteristics.
Inrush Current
When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may
flow instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power
supply. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring,
and routing of connections.
7.
Testing on Application Boards
When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may
subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power
supply should always be turned off completely before connecting or removing it from the test setup during the
inspection process. To prevent damage from static discharge, ground the IC during assembly and use similar
precautions during transport and storage.

Operational Notes – continued
8.
Inter-pin Short and Mounting Errors
Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result
in damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output
pin. Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid
environment) and unintentional solder bridge deposited in between pins during assembly to name a few.
9.
Unused Input Pins
Input pins of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance
and extremely low capacitance. If left unconnected, the electric field from the outside can easily charge it. The
small charge acquired in this way is enough to produce a significant effect on the conduction through the transistor
and cause unexpected operation of the IC. So unless otherwise specified, unused input pins should be connected
to the power supply or ground line.
10. Regarding the Input Pin of the IC
This IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated. P-N
junctions are formed at the intersection of the P layers with the N layers of other elements, creating a parasitic diode
or transistor. For example (refer to figure below):
When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode.
When GND > Pin B, the P-N junction operates as a parasitic transistor.
Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual
interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to
operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should
be avoided.

11. Ceramic Capacitor
When using a ceramic capacitor, determine a capacitance value considering the change of capacitance with
temperature and the decrease in nominal capacitance due to DC bias and others.
