AP1301/2/4/5

Single Coil Fan Motor Full Wave Driver

Features

General Description

- Compatible to a Hall element

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.

- Operating voltage (V_CC) : 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) I_O=500mA_(max)

- Output current(AP1304/5) I_O=350mA_(max)

- Operating temperature (T_opr) : -30ºC to +85ºC

- SOP-8L/ SOP-8L EP package

- Include Thermal Shutdown circuit

Application

- CPU cooling fans

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.
