The TC78S122FNG is a PWM chopper type dual-stepping motor driver. Incorporating two pairs of H-bridge drivers per driver, the TC78S122FNG can drive two DC motors or a single stepping motor per driver simultaneously. Alternatively the two stepping motor drivers can drive up to four brushed DC motors.TC78S122FNG can be run in normal mode or large mode. Large mode means combining H-bridges to reduce Ron down to 0.3 ohm.  The device includes features like over-current detection (ISD), thermal shutdown (TSD) and VM power-on reset circuits.
