MC33887APVW

MC33887APVW is a monolithic H bridge power IC with load current feedback in 20 pin HSOP package. This device is an ideal choice for closed-loop DC motor control. It incorporates internal control logic, a charge pump, gate drive and low RDS(ON) MOSFET output circuitry. TheMC33887APVW is able to control inductive loads with continuous DC load currents up to 5A and with peak current active limiting between 5.2A and 7.8A. The load current feedback feature provides proportional (1/375th of load current) constant current output suitable for monitoring by microcontroller A/D input. This feature facilitates the design of closed loop torque/speed control as well as open load detection. A fault status output pin reports undervoltage, short circuit and overtemperature conditions. Applications include electronic throttle control (ETC), exhaust gas recirculation (EGR), turbo flap control, industrial and medical pumps and motor control.
