The EVALUATION KIT features the MPC17C724 compact monolithic dual channel H-Bridge power IC, which is ideal for portable electronic applications containing bipolar stepper motors or brush DC motors, such as those used in camera lenses and shutters.

The MPC17C724 can operate efficiently with supply voltages from 2.7 V to 5.5 V and can provide continuous motor drive currents of 0.4 A with low RDS(ON) of 1.0 Ω. It is easily interfaced to low-cost MCUs via parallel 3.0 V- or 5.0 V-compatible logic and has built-in shoot-through current protection circuit and undervoltage detector to avoid malfunction. The MPC17C724 has four output control modes: Forward, Reverse, Brake, and Tri-State (High Impedance). The H-bridge outputs are designed to be independently PWM'ed at up to 200 kHz for speed/torque and current control.
