MC33887APVWR2

MC33887APVWR2 is a monolithic H-bridge power IC with a load current feedback feature making it ideal for closed-loop DC motor control. The IC incorporates internal control logic, charge pump, gate drive, and low RDS(on) MOSFET output circuitry. The 33887 is able to control inductive loads with continuous DC load currents up to 5.0 A, and with peak current active limiting between 5.2 A and 7.8 A. Output loads can be pulse width modulated at frequencies up to 10KHz. The load current feedback feature provides a proportional (1/375th of the load current) constant-current output suitable for monitoring by a microcontroller’s A/D input. This feature facilitates the design of closed-loop torque/ speed control as well as open load detection. It meets the stringent requirements of automotive applications and is AEC-Q100 grade 1 qualified. Typical applications include electronic throttle control, exhaust gas recirculation, turbo flap control and industrial and medical pumps and motor control.
