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
• Possible to respond to 3V control voltage and 6V motor voltage device
• Low power consumption
• Low-temperature resistance 1.2Ω
• Built-in charge pump circuit
• Built-in low voltage reset and thermal shutdown circuit
• Four mode function forward/reverse, brake, stop.
• Compact TSSOP24 package

Remarks
1. It shows current dissipation of VM1,2 pin in output OFF state.
2. It shows current dissipation of VCC pin in stand-by state.
(The standard current depends on EN pin pull-down resistance.)
3. It shows current dissipation of VCC pin in state of EN = 5V (stand-by), including current dissipation of VG pin.
4. For IN1, IN2, IN3 and IN4 pins, no pull-down and pull-up resistance is needed. (High impedance pin)
5. It shows sum of upper and lower saturation voltages of OUT pin.
6. It controls charge-pump oscillation and makes specified voltage.
7. When low voltage is detected, the lower output is turned OFF.
8. When thermal protection circuit is activated, the lower output is turned OFF.
When the heat temperature is fallen, it is turned ON again.
9. IG (VG pin load current) = 500μA
10. It shows VG pin current dissipation in state of PWM input for IN pin.
11. It specifies start-up time from 10% to 90% when VG is in non-load state
(when setting the capacitor between VG and GND to 0.1μF and VCC is 5V).
12. It specifies 10% to 90% for start-up and 90% to 10% for shut-down.

*1: Connect a kickback absorption capacitor directly near IC. Coil kickback may cause rise of the voltage of VM line, and
the voltage exceeding the maximum rating may be applied momentarily, resulting in deterioration or damage of IC.
