Overview

The LB1839M 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 of the LB1839M 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 MFP14S package.
