www.DataSheet4U.com AP1346/1347 Two Coil Fan Motor Predriver „ Features - Compatible to a Hall element - Operating voltage (VCC) : 4V to 28V - Lock shutdown and automatic restart - Rotation detection (RD) output name as AP1347 - Speed indication output (FG) named as AP1346 - Output current IO=70mA (max) - Operating temperature (Topr) : -30ºC to +85ºC - SOP8 package - Include Thermal Shutdown circuit „ General Description The AP1346/7 fan motor predriver is suited for two-coil brush-less DC fan. All functions, including lock shutdown, automatic restart, speed indication (FG), have been integrated into one chip. When the motor is under lock condition, lock shutdown function turns off the output. When the lock condition is removed, the IC automatically restarts and allows DC fan to run. In addition, the FG function is to indicate the rotation speed and the RD function is to detect the motor status. „ Application - High voltage, high current brushless DC fan „ Pin Assignment ( Top view ) VCC HS(+) FG/RD HS(-) 1 2 AP1346/1347 3 4 SOP-8L 6 5 CT GND 8 7 OUT1 OUT2 „ Pin Descriptions Name VCC HS(+) FG /RD HS(-) GND CT OUT2 OUT1 Description Power input Hall input Speed indication / detection Hall input Ground Timing capacitor Driver output Driver output Rotation „ Ordering Information AP134X X - X X X Part Number 6: AP1346 7: AP1347 Wafer Body Package Lead Packing Blank : Tube A : Taping S: SOP-8L L: Lead Free Blank or A~Z : if necessary Blank: Normal to specify This data...
