LV8401V
Overview
Bi-CMOS IC
Forward/Reverse Motor Driver
LV8401T is a 1ch 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 (0.35 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
* 1ch forward/reverse motor driver * Low power consumption * Low-temperature resistance 0.6 * Built-in constant current output circuit * Built-in low voltage reset and thermal shutdown circuit * Four mode function forward/reverse, brake, stop.

Remarks 1. Current consumption when output at the VM pin is off. 2. Current consumption at the VCC pin when in standby mode. 3. Current consumption at the VM pin when EN is high. 4. Current consumption at the VCC pin when EN is high. 5. These input pins (IN1, IN2, and ICTRL) have an internal pull-down resistor and the EN pin an internal pull-up resistor. 6. Sum of the top and bottom side output on resistance. 7. Leakage current when the constant current output is off. 8. Current value that is determined by dividing the internal reference voltage (0.2V) by RSET. 9. ISET pin voltage when the constant current output block is active. 10. ON resistance value of the constant current output block. 11. All output transistors are turned off if a low-voltage is detected. 12. All output transistors are turned off if the thermal protection circuit is activated. They are turned on again as the temperature goes down. 13. Rising time from 10 to 90% and falling time from 90 to 10% are specified.

*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 40 is connected between the ISET and SGND.
