Ordering number : ENA1888A Bi-CMOS IC LV8402V 2ch Forward/Reverse Motor Driver Overview LV8402T 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. • Low power consumption. • Low ON resistance 0.75Ω. • Built-in low voltage reset and thermal shutdown circuit. • 3 mode function forward/reverse, brake. • Built-in charge pump.
