The TC78H653FTG is a dual H-bridge driver IC for one or

two DC brushed motors or one Stepping motor which

incorporates DMOS with low ON resistance in output

transistors. The TC78H653FTG has selectable forward,

reverse, stop or brake mode. Over current detection, thermal

shutdown, and under voltage lockout functions are

implemented. The device is housed in a compact QFN-16 3.0

mm×3.0 mm package.
