17C724
The 17C724 is a SMARTMOS 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.
The 17C724 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 . 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 17C724 has four output control modes: forward, reverse,
brake, and tri-state (high-impedance). The H-Bridge outputs are
designed to be independently PWMed at up to 200 kHz for speed/
torque and current control.
