Overview
The LV8773 is a 2-channel H-bridge driver IC, which supports forward, reverse, brake, and standby of a motor. It is
ideally suited for driving brushed DC motors and stepping motors used in office equipment and amusement
applications.
Features
• BiCDMOS process IC
• Low on resistance (upper side : 0.3Ω ; lower side : 0.25Ω ; total of upper and lower : 0.55Ω ; Ta = 25°C, IO = 2A)
• Motor current selectable in two steps
• Output short-circuit protection circuit (selectable from latch-type or auto-reset-type) incorporated
• Unusual condition warning output pins
• No control power supply required
