LV11961HA
Overview
LV11961HA is a driver IC for single-phase fan motor that easily
implements direct PWM motor drive system with excellent efficiency.
LV11961HA is optimal for fan motor drive in personal computer power
supply systems and CPU cooling systems.
Feature
 Single-phase full wave drive (built-in power FETs)
 Speed control function by DC voltage input to VTH pin
 Minimum speed adjustment by fixed voltage input to RMI pin
 Soft start-up function by SFS pin
 Regulated voltage output pin for Hall bias
 Built-in lock protector and auto recovery circuit
 FG signal output pin, RD signal output pin
 Built-in TSD (Thermal shutdown) circuit
Typical Applications
 Fan motor units
 Note PCs , Desk top PCs
 Projectors
