General Description
L9909 General Description
The output current at ROSC pin is mirrored to COSC pin with a proper direction according to its voltage slope.
The triangular wave form at COSC pin, being compared with a threshold, defines the PWMduty cycle at the motor driver outputM+ and M-. The oscillator also supplies the time base for the switch off and switch on delays and the Time Out Counter.
The typical oscillator period is: Tosc = 7.04 x Rosc x Cosc
