Status of high-side and low-side switches A; open drain output.
This pin must be connected to an external pull-up resistor. When
externally pulled low, it disables half-bridge A. In case of fault
detection (thermal shutdown of a high-side FET or excessive
ON-state voltage drop across a low-side FET), this pin is pulled
low by the device (see
