LB1909MC

Ordering number : ENA2037C LB1909MC Monolithic Digital IC Stepping Motor Driver IC Overview http://onsemi.com The LB1909MC is motor driver IC that can operate on a wide supply voltage range (2.5V to 16V). The IC is ideal for use in 2-phase excitation drive of general-purpose 2-phase bipolar stepping motors including dampers for refrigerators. Features Wide supply voltage range : 2.5V to 16V Low saturation voltage : VO(sat) = 0.25V typ at IO = 200mA. Built-in shoot-through current protection circuit. No standby current consumption (or zero). Built-in thermal shutdown circuit. Small package : SOIC10 Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Maximum power source voltage Applied output voltage Applied input voltage GND pin outflow current Allowable power consumption Operating temperature Storage temperature Symbol VCC max VOUT max VIN max IGND Pd max Topr Tstg Mounted on the specified board * Conditions Ratings -0.3 to +20 -0.3 to +20 -0.3 to +18 800 820 -30 to +85 -40 to +150 Unit V V V mA mW °C °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.
