Ordering number: ENA1340D LV8405V Bi-CMOS IC 2ch Forward/Reverse Motor Driver http://onsemi.com 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 ON resistance 0.75Ω. • Built-in low voltage reset and thermal shutdown circuit. • Four mode function forward/reverse, brake, stop. • Built-in charge pump.

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.
