BD6718FV - DC Brushless Fan Motor Drivers

Download the BD6718FV datasheet PDF. This datasheet also covers the BD6709FS variant, as both devices belong to the same dc brushless fan motor drivers family and are provided as variant models within a single manufacturer datasheet.

General Description

This is the summary of models that suit for 12V speed controllable fan for desktop PC and general consumer equipment.

They employ Bi-CDMOS process, and realize low ON resistance, low power consumption.

They incorporate lock protection and automatic restart circuit, current limiting circuit.
