Ordering number : EN3518E Monolithic Digital IC LB1830M Low-Voltage, Low-Saturation Bidirectional Motor Driver Overview The LB1830M is a low-saturation bidirectional motor driver IC with brake function for use in low-voltage applications. As both of forward and reverse outputs are regulated, it is especially suited for use in portable equipment. Features • Wide operating voltage range: 3.0 to 9.0 V • Low saturation voltage: 0.2V at IO = 40mA (typ) • Low current drain at standby mode (0.1μA or less) • Brake function • Regulated voltage value (forward/reverse) setting available by one variable resistor • Regulated output/saturation output switching available • Built-in spark killer diodes • Small package: MFP10S Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Ratings Unit maximum supply voltage VCC max, VS max Output current IM max Input supply voltage VIN Allowable power dissipation Pd max 0.55 W Operating temperature Topr -20 to +80 °C Storage temperature Tstg -40 to +125 °C Independent IC Mounted on a specified board * 10.5 V 500 mA -0.3 to +10 V 0.4 W * Specified board: 30mm × 30mm × 1.5mm, 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.
