www.DataSheet4U.com Freescale Semiconductor Technical Data Document Number: MC33887 Rev. 12.0, 2/2007 5.0 A H-Bridge with Load Current Feedback The 33887 is a monolithic H-Bridge Power IC with a load current feedback feature making it ideal for closed-loop DC motor control. The IC incorporates internal control logic, charge pump, gate drive, and low RDS(ON) MOSFET output circuitry. The 33887 is able to control inductive loads with continuous DC load currents up to 5.0 A, and with peak current active limiting between 5.2 A and 7.8 A. Output loads can be pulse width modulated (PWM-ed) at frequencies up to 10 kHz. The load current feedback feature provides a proportional (1/ 375th of the load current) constant-current output suitable for monitoring by a microcontroller’s A/D input.
