MC33886PVWR2

MC33886PVWR2 is a monolithic H-bridge IC ideal for fractional horsepower DC-motor and bi-directional thrust solenoid control. The IC incorporates internal control logic, charge pump, gate drive, and low RDS(ON) MOSFET output circuitry. MC33886 is able to control continuous inductive DC load currents up to 5A. Output loads can be pulse width modulated at frequencies up to 10KHz. A Fault Status output reports undervoltage, short-circuit and overtemperature conditions. Two independent inputs control the two half-bridge totem-pole outputs. Two disable inputs force the H-Bridge outputs to tri-state (exhibit high-impedance). The IC is available in a surface mount power package with exposed pad for heatsinking. Device is powered by SMARTMOS technology. Typical applications include automotive systems, DC motor control in industrial and robotic systems, DC motor and actuator control in boats, RVs and marine systems, powered machine and hand tools, antenna rotors and dish positioning systems.
