LB1935FA
Monolithic Digital IC
Stepping Motor Driver IC
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

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.
