LV8402GP
Bi-CMOS IC
2ch Forward/Reverse Motor Driver
http://onsemi.com
Overview
LV8402GP 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 ON resistance 0.75Ω.
• Built-in low voltage reset and thermal shutdown circuit.
• 4 mode function forward/reverse, brake and standby.
• Built-in charge pump.
• Built-in EXTRA mode for PWM port reduction when a motor drives by two phase excitation.

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current,
high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
