Absolute maximum ratings If excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can break down the devices, thus making impossible to identify breaking mode, such as a short circuit or an open circuit. If any over rated values will expect to exceed the absolute maximum ratings, consider adding circuit protection devices, such as fuses ...

... BD9006F, BD9006HFP, BD9007F, BD9007HFP 8. GND wiring pattern It is recommended to separate the large-current GND pattern from the small-signal GND pattern and establish a single ground at the reference point of the set PCB, so that resistance to the wiring pattern and voltage fluctuations due to a large current will cause on fluctuations in voltages of the small-signal GND. Prevent fluctuations in the GND wiring pattern of external parts ...
