LB1964T

No. 6188-1/4

Overview

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.

Features

• Single-phase full-wave drive

• Low-saturation output (upper side + lower side saturation

voltage: Vosat (total) = 0.3V typ., Io = 100 mA)

• Ultraminiature package (3.0

• FG output

• Built-in thermal protection circuit
