DC Brushless Fan Motor Drivers
BH6766FVM, BD6989FVM, BH6799FVM, BH6789FVM
Description
This is the summary of models that suit for notebook PC cooling fan. They employ Bi-CMOS and Bi-CDMOS process, and
realize low ON resistor, low power consumption, and quiet drive. They also incorporate lock protection and automatic
restart circuit which does not require external capacitor.
Features
1) Soft switched drive
2) Incorporating lock protection and automatic restart circuit(BD6989FVMBH6799FVMBH6789FVM)
3) Rotating speed pulse signal (FG) output (BD6989FVMBH6799FVMBH6766FVM)
4) Lock alarm signal (AL) output (BH6789FVM)
5) PWM speed control (BD6989FVM)
6) MSOP8 compact package
Applications
For compact 5V fan such as notebook PC cooling fan
