LB1830M_11

Ordering number : EN3518E Monolithic Digital IC LB1830M Overview Low-Voltage, Low-Saturation Bidirectional Motor Driver 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 Parameter Absolute Maximum Ratings at Ta = 25°C Symbol VCC max, VS max IM max VIN Pd max Independent IC Mounted on a specified board * Operating temperature Storage temperature Topr Tstg Conditions Ratings 10.5 500 -0.3 to +10 0.4 0.55 -20 to +80 -40 to +125 Unit V mA V W W °C °C maximum supply voltage Output current Input supply voltage Allowable power dissipation * 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.
