Overview
TECHNICAL NOTE DC Brushless Motor Drivers for Cooling Fans Speed Controllable Single-phase Full-wave DC Brushless Fan Motor Drivers BD6709FS, BD6718FV, BD6721FS, BD6722FS ●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.
●Features 1) Power Tr incorporated (BD6709FS、BD6721FS) 2) Pre-driver compatible for external Tr (BD6718FV) 3) Low side power Tr incorporated half pre-driver (BD6722FS) 4) Current limiting circuit 5) PWM soft switching driver (BD6721FS、BD6722FS) 6) Soft start circuit (BD6722FS) 7) Lock protection and automatic restart circuit 8) Rotating speed pulse signal (FG) output 9) Lock alarm signal (AL) output (BD6718FV、BD6721FS、BD6722FS) ● Application For 12V fan for desktop PC, server and general consumer equipment ●Lineup 12V speed controllable single-phase full-wave Soft switching not available Soft switching available Power Tr incorporated BD6709FS Pre-driver BD6718FV Power Tr incorporated BD6721FS Half pre-driver BD6722FS Jan.
