Ordering number : ENA1960 LV8402GP Bi-CMOS IC 2ch Forward/Reverse Motor Driver 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 (0.75Ω 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. Functions • 2ch forward/reverse motor driver. • Built-in low voltage reset and thermal shutdown circuit. • Low power consumption. • 4 mode function forward/reverse, brake and standby. • Low-temperature resistance 0.75Ω. • Built-in charge pump. • Built-in EXTRA mode for PWM port reduction when a motor drives by two phase excitation.
