KIT33887EKEVBE

The KIT33887EKEVBE is a 33887, 120mohm RDSON typical with Sleep mode and current sense evaluation module. 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 5A, and with peak current active limiting between 5.2A and 7.8A. 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. This feature facilitates the design of closed-loop torque/speed control as well as open load detection.
