Ordering number : ENA2026 Monolithic Digital IC LB1638MC Low-Voltage, Low-Saturation Bidirectional Motor Driver Overview The LB1638MC 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 Maximum supply voltage Symbol Conditions Ratings Unit VCC max -0.3 to +10.5 VS max -0.3 to +10.5 V -0.3 to VCC+ VSF V Output applied voltage VOUT Input applied voltage VIN Ground pin flow-out current IGND Mounted on a specified board V -0.3 to +10.0 V 1.0 A 820 mW Allowable power dissipation Pd max Operating temperature Topr -20 to +75 °C Storage temperature Tstg -40 to +125 °C * Specified board: 114.3mm × 76.1mm × 1.6mm, glass epoxy 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.
