feature provides a proportional (0.24% of the load current) current output suitable for monitoring by a microcontroller’s A/D input. A status flag output reports undervoltage, overcurrent, and overtemperature fault conditions. Two independent inputs provide polarity control of two half-bridge totem-pole outputs. The disable inputs are provided to force the H-Bridge outputs to tri-state (high-impedance off-state).
