Dc Motor Driver With Position Control

The output current at ROSC pin L9909 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 By STMicroelectronics
