L6713A has three different supplies: VCC pin to supply the internal control logic, VCCDRx

to supply the low side drivers and BOOTx to supply the high side drivers. If the voltage at

pins VCC and VCCDRx are not above the turn on thresholds specified in the Electrical

characteristics, the device is shut down: all drivers keep the MOSFETs OFF to show high

impedance to the load. Once the device is correctly supplied, proper operation is assured

and the device can be driven by the OUTEN pin to control the power sequencing. Setting

the pin free, the device implements a soft-start up to the programmed voltage. Shorting the

pin to SGND, it resets the device (SS_END/PGOOD is shorted to SGND in this condition)

from any latched condition and also disables the device keeping all the MOSFET turned

OFF to show high impedance to the load.
