LB1840M
Low-voltage/Low-saturation Bidirectional
Variable Constant-voltage Motor Driver
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.
Package Dimensions
unit: mm
3111-MFP14S
[LB1840M]
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.
