Ordering number : ENA1382B LV8406T Bi-CMOS IC 2ch Forward/Reverse Motor Driver http://onsemi.com 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. Specifications Absolute Maximum Ratings at Ta = 25°C, SGND = PGND = 0V Parameter Symbol Conditions VM1, VM2 Ratings Unit Power supply voltage (for load) VM max Power supply voltage (for control) VCC max Output current IO max Output peak current IO peak Input voltage VIN max Allowable power dissipation Pd max Operating temperature Topr -30 to +85 °C Storage temperature Tstg -55 to +150 °C t ≤ 10ms Mounted on a specified board* -0.5 to 16.0 V -0.5 to 6.0 V 1.4 A 2.5 A -0.5 to VCC+0.5 V 3.1 W * Specified board : 90mm × 90mm × 1.6mm, glass epoxy 2-layer board (2S0P). 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.

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.
