... BD63843EFV, BD63847EFV ○Under Voltage Lock Out (UVLO) This IC has a built-in under voltage lock out function to prevent false operation such as IC output during power supply under voltage. When the applied voltage to the VCC terminal goes under 15V (Typ.), the motor output is set to OPEN. This switching voltage has a 1V (Typ ...

... BD63843EFV, BD63847EFV ●Usage Notes (1) Absolute maximum ratings An 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 ...
