LV8402GP
Overview
LV8402GP is a 2ch forward/reverse motor driver IC using D-MOS FET for output stage. As MOS circuit is
used, it supports the PWM input. Its features are that the on resistance (0.75 typ) and current dissipation
are low.
It also provides protection functions such as heat protection circuit and reduced voltage detection and is
optimal for the motors that need high-current.
Function
2ch forward/reverse motor driver.
Low power consumption
Low-ON resistance 0.75.
Built-in EXTRA mode for PWM port reduction when a motor drives by two phase excitation.
Built-in low voltage reset and thermal shutdown circuit.
4 mode function forward/reverse, brake and standby
Built-in charge pump.
Typical Applications
SLR-Camera lens anti-shake/Iris /auto focus control
LCD projector lens focus /pan-tilt drive
Battery powered toys and games
Portable printers/scanners
Robotic actuators and pumps
