AP1301/2/4/5 Single Coil Fan Motor Full Wave Driver Features General Description - Compatible to a Hall element - Operating voltage (VCC) : 4V to 20V - Lock shutdown and automatic restart - Speed indication output (FG) named as AP1301/4 - Rotation detection output (RD) named as AP1302/5 - Output current(AP1301/2) IO=500mA(max) - Output current(AP1304/5) IO=350mA(max) - Operating temperature (Topr) : -30ºC to +85ºC - SOP-8L/ SOP-8L EP package - Include Thermal Shutdown circuit The AP1304/5 is single phase full wave drive design, which is suited for small fans (such as CPU cooling fans). The low switching noise and effective motor drive are another advantage. All functions, including lock shutdown, automatic restart, rotation detection (RD), and speed indication output (FG) have been incorporated into one chip. When the motor is under lock condition, lock shutdown function turns off the output current. When the lock condition is removed, the IC automatically restarts and allows DC fan to run. In addition, the RD function is to detect the motor status and the FG is to provide the rotation speed. Application The AP1301/2 are heat sink version of AP1304/5. From function wise, AP1301 is the same as AP1304, and AP1302 is the same as AP1305. - CPU cooling fans Pin Descriptions Pin Assignment Name ( Top view ) IN- 1 IN+ 2 8 RD/FG 7 VCC VCC IN+ RD/FG INGND CT OUT2 OUT1 AP1301/2/4/5 CT 3 6 OUT2 OUT1 4 5 GND Description Power input Hall input Rotation detection / Speed indication Hall input Ground Timing capacitor Driver output Driver output SOP-8L Ordering Information AP130X X - X X X Function - RD output (1305) without heat sink - FG output (1304) - RD output (1302) with heat sink - FG output (1301) Wafer Body Blank or A~Z : if necessary to specify Package Lead Blank: Normal S: SOP-8L SP: SOP-8L EP L: Lead Free Packing Blank : Tube A : Taping This datasheet contains new product information.
