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

  • Operates 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
  • Easily interfaced to low-cost MCUs via parallel 3.0 V- or 5.0 V-compatible logic
  • Built-in shoot-through current protection circuit and undervoltage detector to avoid malfunction
  • The H-bridge outputs are designed to be independently PWM'ed at up to 200 kHz for speed/torque and current control
