Pin Descriptions - continued

1. VCC1 (Input-side Power Supply Pin)

The VCC1 pin is a power supply pin on the input side. To suppress voltage fluctuations due to the current to drive internal

transformers, connect a bypass capacitor between the VCC1 and the GND1 pins.

2. GND1 (Input-side Ground Pin)

The GND1 pin is a ground pin on the input side.

3. VCC2 (Output-side Power Supply Pin)

The VCC2 pin is a power supply pin on the output side. To reduce voltage fluctuations due to OUT pin output current,

connect a bypass capacitor between the VCC2 and the GND2 pins.

4. GND2 (Output-side Ground Pin)

The GND2 pin is a ground pin on the output side.

5. INA, INB (Control Input A/B Pin)

The INA and INB pins are used to determine output logic.

6. OUT (Output Pin)

The OUT pin is used to drive the gate of a power device.

7. MC (Miller Clamp Pin)

The MC pin is for preventing the increase in gate voltage due to the Miller current of the power device connected to the

OUT pin. If the Miller Clamp function is not used, short-circuit the MC pin to the GND2 pin.

2. Under-Voltage Lockout (UVLO) Function

The BM61S41RFV-C has the Under-Voltage Lockout (UVLO) function both on the Input-side and the output-side. When

the power supply voltage drops to the UVLO ON voltage (input-side Typ 4.0 V, output-side 14.5 V), the OUT pin will output

the “L” signal. In addition, to prevent malfunctions due to noises, a mask time of t_UVLO1MSK(Typ 1.5 µs) and t_UVLO2MSK(Typ

2.9 µs) are set on both the input-side and the output-side. After the UVLO on Input-side is released, the input signal will

take effect from when the time after the input signal switches.

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.

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. 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.

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.

8.

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.

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.
