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

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.
