LB1964T
Fan Motor Single-Phase Full-Wave Driver
Overview
Package Dimensions
The LB1964T is a driver for single-phase bipolar drive fan
motors that features compact and low-profile MSOP–8
package. Low-saturation output and low-voltage operation
make it ideal for applications that require small size and
high efficiency, such as notebook computers and CPU
cooling fans.
