Oscillator frequency
The frequency of the internal oscillator can be programmed using external resistor and
capacitor.
The nominal oscillator frequency can be calculated using the following equation:
Equation 1
Where R
The device can be driven in "shut down" condition keeping the C
some cares have to be taken:

When CF is to GND the high side driver is off and the low side is on
The forced discharge of the oscillator capacitor C
simple way to do this is to limit the current discharge with a resistive path imposing
