Overview
The LB1840M is a low-voltage, low-saturation, three-input type two-channel bidirectional motor driver that permits switching between constant-voltage regulated output and saturated output. The design is ideal for a two-phase bipolar driver for stepping motors.

Features
• Wide operating voltage range (3.0 to 9.0 V).
• Low saturation voltage VO(sat) = 0.40 V at IO = 200 mA.
• Consumes almost no current in standby mode (0.1 µA or less).
• Permits setting of bidirectional constant-voltage regulated value.
• Three-input type that is ideal for a two-phase bipolar driver.
• Permits switching between constant-voltage regulated output and saturated output.
• Built in reference voltage coupled to input.
• Compact MFP-14S package.
