The MC33886 is a monolithic power IC comprising control logic, charge pump, gate drive, and low R DS(on)MOSFET output H-Bridge circuitry into a small surface mount package.
It is designed to drive inductive loads with rms currents to 5.2 A in both directions. In addition,the current drive can be pulse width modulated (PWM)at frequencies to 10 kHz. Undervoltage, overtemperature, and overcurrent conditions are detected and reported via a status flag output.
Output control is via two independent inputs (forward, reverse, free- wheeling low, and freewheeling high are possible active output states). Two disable inputs are provided, one Low =True and one High =True, either of which will place the outputs into a high impedance OFF state.
Typical applications include: DC-motor acme lead screw actuators, servo gear actuators, bi-directional thrust solenoids, and fractional horsepower DC-motor control.
The KIT33887EKEVBE is the recommended evaluation board for the MC33886
