• Production Lifecycle Status

The Texas Instruments DRV8873SPWPRQ1 is an automotive-qualified H-bridge motor driver for brushed DC motors, with integrated current sensing and feedback, in a 24-pin HTSSOP package. It operates from a 4.5V to 38V supply with a nominal supply current of 5mA and a 400k Hz switching frequency. TI rates the device from -40C to 125C ambient with a maximum junction temperature of 150C, and lists it in Production lifecycle status. Two record discrepancies are worth noting before you quote it: the product name says 40V while the Max Supply Voltage attribute reads 38V, and the RoHS attribute reads Non-Compliant on an automotive Q1 part.

An automotive H-bridge driver of this class drives bidirectional brushed DC loads from a vehicle 12V or 24V bus: power windows, sunroofs, seat and mirror actuators, HVAC flaps, pumps, latches and throttle or valve actuators. The integrated current sensing lets the controller detect stall, measure load torque and implement pinch protection without an external shunt amplifier. Buyers are automotive tier-one suppliers and industrial-actuator makers who need the -40C to 125C ambient rating. The thermally enhanced HTSSOP requires a soldered thermal pad and copper spreading area to reach the higher current levels the family supports.
