Bi-CMOS IC
LV8405V
2ch Forward/Reverse Motor Driver
Overview
LV8405T 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.
• Low power consumption.
• Low-temperature resistance 0.75Ω.
• Built-in low voltage reset and thermal shutdown circuit.
• Four mode function forward/reverse, brake, stop.
• Built-in charge pump.

1. Current consumption when output at the VM pin is off.
2. Current consumption at the VCC pin when VCC is 3V and IN1 to IN4 are all 0V (standby mode).
3. Pins IN 1, 2, 3, and 4 are all pulled down.
4. Sum of upper and lower saturation voltages of OUT pin divided by the current.
5. All power transistors are turned off if a low VCC condition is detected.
6. All output transistors are turned off if the thermal protection circuit is activated. They are turned on again as the
temperature goes down.
7. Rising time from 10 to 90% and falling time from 90 to 10% are specified.
