LB1909MC

Overview

The LB1909MC is a 2-channel low saturation voltage forward/reverse motor driver that can operate on a wide supply

voltage range (2.5V to 16V). The IC is ideal for use in 2-phase excitation drive of general-purpose 2-phase bipolar stepping

motors including dampers for refrigerators.

Features

• Wide supply voltage range : 2.5V to 16V

• Low saturation voltage : VO(sat) = 0.25V typ at IO = 200mA.

• Built-in shoot-through current protection circuit.

• No standby current consumption (or zero).

• Built-in thermal shutdown circuit.

• Small package : SOIC10

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.
