overvoltage (OV) shutdown. If one of the supply voltage
drops below the undervoltage threshold or rises above the
overvoltage threshold, the gate outputs are switched LOW in
order to switch off the external MOSFETs. When the supply
returns to a level that is above the UV threshold or below the
OV threshold, the device resumes normal operation
according to the established condition of the input pins.

compatible inputs with hysteresis. IN_HSn and IN_LSn
independently control GATE_HSn and GATE_LSn,
respectively.
