Fig. 12: Leakage current of driver output stages measured
as current out of SH Pin to GND
Remark:
The leakage current of the driver output stage is taken from the bootstrap capacitors C_BX. When an external
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.
