LA1909M
Overview
The LB1909M 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 : MFP10S (225mil)
