Typ. undervoltage shut down level

Typ. Current consumption of output stage

Conditions:

Vs=12V; measured with V(BHx=12V) and potentiometer between SHx and GND

Parameter:

Remark:

high-side Mosfet is switched on, it is impossible to replace this current. The capacitor will be discharged as long

as this Mosfet stays on. The time until this output stage reaches the undervoltage shut-down can be determined

by the size of the capacitor, the initial capacitor voltage, the leakage current taken out of this capacitor and the

undervoltage lock-out level.
