Ordering number : ENA1996 LV8417CS Bi-CMOS IC Forward/Reverse Motor Driver http://onsemi.com Overview The LV8417CS is a 1-channel H bridge motor driver IC. The package size is extremely small with wafer level package (WLP). Moreover, the on-resistance is low (upper and lower total 0.27Ω typ.). The application voltage range is wide (2.0V to 10.5V). The H bridge of this IC is P-N composition and thereby reduces the external parts without need of charge pump. Therefore, LV8417CS realizes reduction of mounting area which enables lower cost and smaller application size. Functions • H-bridge 1-channel forward/reverse motor driver • IO max=1.0A (t≤100ms 2.0A, t≤10ms 3.8A) • BiCDMOS process • Built-in low voltage reset and thermal shutdown circuit • Output ON resistance (Upper and lower total 0.27Ω; Ts=25°C, IO=1.0A) Specifications Maximum Ratings at Ta = 25°C, SGND = PGND = 0V Parameter Symbol Conditions Ratings Unit Power supply voltage (for load) VM max -0.5 to 12.6 V Power supply voltage (for control) VCC max Output current IO max Output peak current IO peak1 t ≤ 100ms IO peak2 t ≤ 10ms Input voltage VIN max Allowable power dissipation Pd max Operating temperature Topr -20 to +85 °C Storage temperature Tstg -55 to +150 °C -0.5 to 6.0 V 1.0 A 2.0 A 3.8 A -0.5 to VCC+0.5 V Mounted on a specified board * 850 mW * Specified board : 57mm × 57mm × 1.6mm, glass epoxy both side board. 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.
