Application Information
When excessive current flows due to output short circuit or so, ringing occurs by inductance of power source line and IC.
This may cause bad effects on IC operations. In order to avoid this case, a bypass capacitor (CIN) should be connected
across the IN terminal and GND terminal of IC. A 1μF or higher value is recommended. Moreover, in order to decrease
voltage fluctuations of power source line and IC, connect a low ESR capacitor in parallel with CIN. A 10μF to 100μF or higher
is effective.
Pull up /OC output by resistance 10kΩ to 100kΩ.
Set up values for CL which satisfies the application.
This application circuit does not guarantee its operation.
When using the circuit with changes to the external circuit constants, make sure to leave an adequate margin for external
components including AC/DC characteristics as well as dispersion of the IC.
Functional Description
1. Switch Operation
IN terminal and OUT terminal are connected to the drain and the source of switch MOSFET respectively. The IN
terminal is also used as power source input to internal control circuit.
When the switch is turned ON from EN(/EN) control input, the IN and OUT terminals are connected by a 70mΩ (Typ)
switch. In ON status, the switch is bidirectional. Therefore, when the potential of OUT terminal is higher than that of IN
terminal, current flows from OUT to IN terminal. On the other hand, when the switch is turned off, it is possible to
prevent current from flowing reversely from OUT to IN terminal since a parasitic diode between the drain and the
source of switch MOSFET is not present.
2. Thermal Shutdown Circuit (TSD)
If over-current would continue, the temperature of the IC would increase drastically. If the junction temperature goes
beyond 170°C (Typ) in the condition of over-current detection, thermal shutdown circuit operates and turns power
switch off, causing the IC to output a fault flag (/OC). Then, when the junction temperature decreases lower than 150°C
(Typ), the power switch is turned on and the fault flag (/OC) is cancelled. This operation repeats, unless the increase of
chip’s temperature is removed or the output of power switch is turned OFF.
The thermal shutdown circuit operates when the switch is ON (EN(/EN) signal is active).
3. Over-Current Detection (OCD)
The over-current detection circuit limits current (ISC) and outputs fault flag (/OC) when current flowing in each switch
MOSFET exceeds a specified value. The over-current detection circuit works when the switch is on (EN(/EN) signal is
active). There are three types of response against over-current:
(1)
(2)
When the switch is turned on while the output is in short circuit status, the switch goes into current limit status
immediately.
When the output short-circuits or high capacity load is connected while the switch is on, very large current flows
until the over-current limit circuit reacts. When the current detection and limit circuit operates, current limitation is
carried out.

BD82004FVJ-M BD82005FVJ-M
(3)
When the output current increases gradually, current limitation would not operate unless the output current
exceeds the over-current detection value. When it exceeds the detection value, current limitation is carried out.
4. Under-Voltage Lockout (UVLO)
UVLO circuit prevents the switch from turning on until the VIN exceeds 2.3V(Typ). If VIN drops below 2.2V(Typ) while
the switch is still ON, then UVLO shuts off the power switch. UVLO has a hysteresis of 100mV(Typ).
Under-voltage lockout circuit operates when the switch is on (EN(/EN) signal is active).
5. Fault Flag (/OC) Output
Fault flag output is N-MOS open drain output. During detection of over-current and/or thermal shutdown, the output
level will turn low.
Over-current detection has delay filter. This delay filter prevents current detection flags from being sent during
instantaneous events such as inrush current at switch on or during hot plug. If fault flag output is unused, /OC pin
should be connected to ground line or open.

Operational Notes
1. 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.
2. Power Supply Lines
Design the PCB layout pattern to provide low impedance supply lines. Separate the ground and supply lines of the
digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting the analog
block. 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. Ground Voltage
Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition.
4. 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. Thermal Consideration
Should by any chance the power dissipation rating be exceeded the rise in temperature of the chip may result in
deterioration of the properties of the chip. The absolute maximum rating of the Pd stated in this specification is when
the IC is mounted on a 70mm x 70mm x 1.6mm glass epoxy board. In case of exceeding this absolute maximum
rating, increase the board size and copper area to prevent exceeding the Pd rating.
6. Recommended Operating Conditions
These conditions represent a range within which the expected characteristics of the IC can be approximately
obtained. The electrical characteristics are guaranteed under the conditions of each parameter.
7. In rush 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.
8. Operation Under Strong Electromagnetic Field
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.
9. 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.
10. 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.
11. 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.

Operational Notes - continued
12. Regarding the Input Pin of the IC
This monolithic 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.

13. Ceramic Capacitor
When using a ceramic capacitor, determine the dielectric constant considering the change of capacitance with
temperature and the decrease in nominal capacitance due to DC bias and others.
14. Thermal Shutdown Circuit(TSD)
This IC has a built-in thermal shutdown circuit that prevents heat damage to the IC. Normal operation should always
be within the IC’s power dissipation rating. If however the rating is exceeded for a continued period, the junction
temperature (Tj) will rise which will activate the TSD circuit that will turn OFF all output pins. When the Tj falls below
the TSD threshold, the circuits are automatically restored to normal operation.
Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no
circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from
heat damage.
15. Thermal design
Perform thermal design in which there are adequate margins by taking into account the power dissipation (Pd) in actual states of
use.
