Thermal shutdown

The shutdown block generates a signal that turns off the power stage if the temperature of

the internal chip goes higher than a fixed internal threshold (150ºC min

).

The sensing element of the chip is very close to the PDMOS area, so ensuring an accurate

and fast temperature detection.

An hysteresis of approximately 20

Output voltage programming (GS-R12F0002.0 only)

The GS-R12F0002.0 output voltage is 5.54V

±4%, to reduce this value connect a resistor

The resistor must be located very close to the proper pins, to minimize the injected noise

(see Figure 2).

The resistor value is calculated using the following formula:

Loop compensation (GS-R12F0002.0 only)

If required by particular load conditions, it is possible to change the feedback loop

will act as speed up (see Figure 3).
