Ordering number : EN3515C Monolithic Digital IC LB1638 LB1638M Low-Voltage, Low-Saturation Bidirectional Motor Driver Overview The LB1638, LB1638M are low-saturation bidirectional motor driver ICs for use in low-voltage applications. At an IO of 500mA, they have a low saturation output of VO(sat) = 0.75V. They are especially suited for use in compact motor of portable equipment. Features • Low voltage operation (2.5V min.) • Low saturation voltage (upper transistor + lower transistor residual voltage; at IO = 500mA, VO(sat) = 0.75V typ.) • Low current drain at standby mode (ICCO = 0.1µA typ. or less) • Separate logic power supply and motor power supply • Brake function • Built-in spark killer diodes Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Symbol Maximum supply voltage VCC max Output applied voltage VOUT Input applied voltage VIN Ground pin flow-out current IGND Allowable power dissipation Pd max Conditions Ratings Unit -0.3 to +10.5 VS max V -0.3 to +10.5 V -0.3 to VS+VF V -0.3 to +10.0 V 1.0 A LB1638 1.0 W LB1638M: Independent IC 440 mW 550 mW LB1638M: Mounted on a specified board Operating temperature Topr -20 to +75 °C Storage temperature Tstg -40 to +125 °C * Specified board: 30mm × 30mm × 1.5mm, glass epoxy board.
