[Reduced voltage detection]

(1) VDD

The internal control IC of the driver has a function that detects reduced voltage when VDD is supplied. This reduced

voltage threshold level is set to 4V (typ.), and the MOSFET gate voltage specification is 5V ±5%. So, a current flow

through the output when VDD is rising results in the power stress to the MOSFET due to insufficient gate voltage.

To prevent this power stress, set ENABLE = Low when VDD < 4.75V, which is outside the normal operating

supply voltage range of the MOSFET.

(2) VCC

The internal control IC of the driver has a function that detects reduced voltage when VCC is supplied, to prevent

insufficient internal P-channel MOSFET gate voltage. The reduced voltage detection level is set to VCC = 8.8V

(typ.).
