MC33886PVW

Overview

The MC33886PVW is a monolithic H-Bridge integrated circuit designed for fractional horsepower DC-motor and bi-directional thrust solenoid control. It incorporates internal control logic, a charge pump, gate drive, and low RDS(ON) MOSFET output circuitry within a PDSO-20 package. The device supports continuous operation from 5.0 V to 40 V and handles continuous inductive DC load currents up to 5.0 A. Output loads can be pulse width modulated at frequencies up to 10 kHz. Key electrical features include 120 mΩ RDS(ON) H-Bridge MOSFETs, TTL/CMOS compatible inputs, active current limiting via internal constant OFF-time PWM with temperature-dependent threshold reduction, output short-circuit protection, under-voltage shutdown, and fault status reporting.
