Technical Note

BDJ□□□1HFV Series

●Notes for use

1) Absolute Maximum Ratings

An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can

break down devices, thus making impossible to identify breaking mode such as a short circuit or an open circuit. If any

special mode exceeding the absolute maximum ratings is assumed, consideration should be given to take physical safety

measures including the use of fuses, etc.

2) GND voltage

Make setting of the potential of the GND terminal so that it will be maintained at the minimum in any operating state.

3) Pin short and mistake fitting

When mounting the IC on the PCB, pay attention to the orientation of the IC. If there is a placement mistake, the IC may be

burned up.

4) Operation in strong electric field

Be noted that using ICs in the strong electric field can malfunction them.

5) Mutual impedance

Use short and wide wiring tracks for the power supply and ground to keep the mutual impedance

as small as possible. Use a capacitor to keep ripple to a minimum.
