LB1638MC

Ordering number : ENA2026 Monolithic Digital IC LB1638MC Overview Low-Voltage, Low-Saturation Bidirectional Motor Driver 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 Parameter Absolute Maximum Ratings at Ta = 25°C Symbol VCC max VS max Output applied voltage Input applied voltage Ground pin flow-out current Allowable power dissipation Operating temperature Storage temperature VOUT VIN IGND Pd max Topr Tstg Mounted on a specified board Conditions Ratings -0.3 to +10.5 -0.3 to +10.5 -0.3 to VCC+ VSF -0.3 to +10.0 1.0 820 -20 to +75 -40 to +125 Unit V V V V A mW °C °C Maximum supply voltage * 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.
