Ordering number : ENA1135A Bi-CMOS LSI LV8086T Forward/Reverse Motor Driver Overview LV8086T 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 • Built-in charge pump circuit • Compact TSSOP24 package • Possible to respond to 3V control voltage and 6V motor voltage device • Low ON resistance 1.2Ω • Built-in low voltage reset and thermal shutdown circuit • Four mode function forward/reverse, brake, stop.
