ESD protection
Description
The AUIR3200S is a high side mosfet driver for very low
Rdson automotive application. It offers over-current, over-
temperature protection and diagnostic. The over-current
protection is done by monitoring the Vds voltage, the
threshold is programmable by external resistor. The over-
temperature protection uses a thermal sensor. The
AUIR3200S offers diagnostic on the input pin.

Sleep_mode / Diagnostic
Sleep_mode block manages the diagnostic and the sleep_mode. The device enters in sleep mode if input is inactive
during a delay higher than Tsleep.

Wake up sequence
To wake up the part from the sleep mode, the input must be activated at least during Twkp, then the bootstrap regulator is
switched on and the bootstrap capacitor is charged. The output will not be activated during Tpw on rst.
