LV8400V

Overview

The LV8400V 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 LV8400V 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 • Built-in constant current output circuit

• Low power consumption • Built-in low voltage reset and thermal shutdown circuit

• Low output ON resistance 0.33Ω • Four mode function forward/reverse, brake, standby.

*1 : Connect a kickback absorbing capacitor as close as possible to the IC. 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.
