6.0 A H-Bridge with Enable

The 33887 is a monolithic H-Bridge with a Sleep Mode feature 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. The 33887 is able to control continuous inductive DC load currents of 6.0 A. Output loads can be Pulse Width Modulation (PWM) controlled at frequencies to 10 kHz. An internal output current monitoring circuit provides a proportional (1/375th) feedback current output for the microcontroller to monitor the output current and provide closed-loop control.
