ToshibaTC78H653FTG,ELMotor Controller and Driver ICs

Overview

The TC78H653FTG is a dual H-bridge driver IC for one or two Brushed DC motors or one Stepping motor which incorporates DMOS with low ON resistance MOSFETs. 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.
