Open drain
output
Overcurrent detection and thermal protection pin. An
internal open drain transistor pulls to GND when an
overcurrent on one of the high-side MOSFETs is
detected or during thermal protection.

SENSEA Power supply
Half-bridge 1 and half-bridge 2 source pin. This pin
must be connected together with pin SENSEB to power
ground through a sensing power resistor.
