LB1935FA-BH

Ordering number : ENA2060 LB1935FA Monolithic Digital IC Stepping Motor Driver IC http://onsemi.com Overview LB1935FA is IC with forward/reverse motor drive 2-channel in which low saturation voltage and low voltage operation possible. Its small sized package is optimal for 2 phase excitation drive of 2 phase bipolar stepping motors for various portable devices such as digital still cameras. Features • Low saturation voltage, VO (sat) = 0.3V typ at IO = 150mA • Built-in shoot-through current protection circuit • No standby current consumption (or zero) • Built-in thermal shutdown circuit • Micro10 small-sized package Absolute Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Ratings Unit Maximum power source voltage VCC max Applied output voltage VOUT max OUT1, OUT2, OUT3, OUT4 pin Applied input voltage VIN max ENA, IN1, IN2 pin GND Pin outflow current I GND Per channel Allowable power dissipation Pd max With substrate* Operating temperature Topr -20 to +75 °C Storage temperature Tstg -40 to +150 °C -0.3 to +8.0 V VCC+VSF V -0.3 to +8.0 V 400 mA 400 mW * Specified substrate: 20.0mm×10.0mm×0.8mm, paper phenol 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. Please contact us for the further details. Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
