Bi-CMOS
Forward/Reverse Motor Driver
LV8400V 1-channel motor driver using D-MOS output stage operates four modes under program control: forward, reverse, brake, standby. P/N-channel structure used H-bridge output stage, LV8400V features minimal number external component on-resistance (0.33 typical). This optimal driving motors that need large-current.
Functions
1-channel forward/reverse motor driver power consumption output resistance 0.33
Built-in constant current output circuit Built-in voltage reset thermal shutdown circuit Four mode function forward/reverse, brake, standby.
