DESCRIPTION
MPC17C724FS SIMPLIFIED APPLICATION DI-
The MPC17C724FS 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
irises.
3.0 V
The MPC17C724FS 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 Vor 5.0 V-compatible logic and has built-in
shoot-through current protection circuit and
undervoltage detector to avoid malfunction.
The MPC17C724FS has four output control
modes: Forward, Reverse, Brake, and TriState (High Impedance). The H-bridge outputs
are designed to be independently PWM’ed at
up to 200 kHz for speed/torque and current
control.
