Overview
The LB1909MC is motor driver IC 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.
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.
