Revision 1.3
6.4.2 Fan speed control
The W83637HF provides maximum 3 sets for fan PWM speed control. The duty cycle of PWM can be
programmed by a 8-bit registers which are defined in the Bank0 Index 01h, Index 03h and Index 11h.
The default duty cycle is set to 100%, that is, the default 8-bit registers is set to FFh. The expression of
duty can be represented as follows.

The PWM clock frequency also can be program and defined in the Bank0 Index 00h, Index 02h and
Index 10h. The application circuit is shown as follows.
