PWM
- Sets PWM frequency
This pin has an external capacitor attached to set the
PWM frequency for the Phase drive outputs. A
capacitor value of 0.15nF will provide a PWM
frequency of typically 24kHz.

- External transistor driver
- External transistor driver
These are the Phase drive outputs and are open
darlington emitter followers designed to provide up to
80mA of drive to external transistors as shown in the
Application circuits following. The external transistors
in turn drive the fan motor windings.
