5.0 A H-Bridge

The 33886 is a monolithic H-Bridge ideal for fractional horsepower

DC-motor and bi-directional thrust solenoid control. The IC

incorporates internal control logic, charge pump, gate drive, and low

continuous inductive DC load currents up to 5.0 A. Output loads can

be pulse width modulated (PWM-ed) at frequencies up to 10 kHz.

A Fault Status output reports under-voltage, short-circuit, and

over-temperature 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 33886 is parametrically specified over a temperature range of

-40

up to 40 V with derating of the specifications. The IC is available in a

surface mount power package with exposed pad for heatsinking.
