LV8401V

Ordering number : ENA0846A LV8401V Overview Bi-CMOS IC Forward/Reverse Motor Driver The LV8401V is a 1-channel motor driver IC using D-MOS FET for output stage and operates in one of the four modes under program control: forward, reverse, brake, and standby. As the P/N-channel structure is used in the H-bridge output stage, the LV8401V features minimal number of external component and low on-resistance (0.33Ω typical). This IC is optimal for driving motors that need large-current. Functions • 1-channel forward/reverse motor driver • Low power consumption • Low output ON resistance 0.33Ω • Built-in constant current output circuit • Built-in low voltage reset and thermal shutdown circuit • Four mode function forward/reverse, brake, standby.

Characteristics deterioration of the IC or damage may result if an instantaneous voltage surge exceeding the maximum rated value is applied to the VM line due to coil kickback or other causes. *2 : The output constant current (IOUT) is determined by the internal reference voltage and the sense resistor between the ISET and SGND pins. IOUT = Internal reference voltage (0.2V) ÷ Sense resistor (RSET) From the formula above, IOUT = 5mA when a sense resistor of 40Ω is connected between the ISET and SGND.
