LV8406T
2ch Forward/Reverse Motor Driver
Overview
LV8406T is a 2-channel 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
• 2-channel forward/reverse motor driver.
• Low power consumption.
• Low-ON resistance 0.75Ω.
• Built-in low voltage reset and thermal shutdown circuit.
• Four mode function forward/reverse, brake, stop.
• Built-in charge pump.

Cautions
1) The data for the case with the Exposed Die-Pad substrate mounted shows the values when 90% or more of the
Exposed Die-Pad is wet.
2) For the set design, employ the derating design with sufficient margin.
Stresses to be derated include the voltage, current, junction temperature, power loss, and mechanical stresses such as
vibration, impact, and tension. Accordingly, the design must ensure these stresses to be as low or small as possible.
The guideline for ordinary derating is shown below :
(1)Maximum value 80% or less for the voltage rating
(2)Maximum value 80% or less for the current rating
(3)Maximum value 80% or less for the temperature rating
3) After the set design, be sure to verify the design with the actual product.
Confirm the solder joint state and verify also the reliability of solder joint for the Exposed Die-Pad, etc.
Any void or deterioration, if observed in the solder joint of these parts, causes deteriorated thermal conduction,
possibly resulting in thermal destruction of IC.

* Connect a kickback absorption capacitor as near as possible to the IC. Coil kickback may cause increase in VM line
voltage, and a voltage exceeding the maximum rating may be applied momentarily to the IC, which results in
deterioration or damage of the IC
* The pin VS is a terminal that supplies a source power supply of the charge pump circuit.
The charge pump voltage, VG = VS + VCC is generated.
Apply the high voltage of VM1 or VM2.
