TC78H653FTG Toshiba CDMOS Integrated Circuit Silicon Monolithic TC78H653FTG 1.8-V Dual H-bridge driver IC 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 mm3.0 mm package. P-VQFN16-0303-0.50-001 Weight: 0.02 g (typ.)
