Document Number: MC33186 Freescale Semiconductor Rev. 8.0, 4/2013 Technical Data H-Bridge Driver 33186 The 33186 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 R MOSFET output circuitry. The 33186 is able to control DS(ON) continuous inductive DC load currents up to 5.0 A. Output loads can H-BRIDGE MOTOR DRIVER be pulse width modulated (PWMed) at frequencies up to 10 kHz. This device is powered by SMARTMOS technology. The 33186 is parametrically specified over a temperature range of -40 C T 125 C, 5.0 V V+ 28 V. The IC can also be operated A up to 40 V with de-rating of the specifications. The IC is available in a surface mount power package with exposed pad for heat sinking.
