LB11963T
Overview
The LB11963T is a single-phase bipolar drive fan motor driver. Incorporating 1/2 FG output for 8-pole fan motors in a
miniature MSOP8 package, it is optimum for driving compact fan motors used in the notebook PC.
This IC is pin-compatible to the LB11964T with normal FG output, and a common circuit board can be used for both 4-
and 8-pole motors.
Functions
Single-phase full-wave drive
The built-in regeneration circuit makes it possible to use a reverse connection prevention diode.
1/2FG output
