Enable and disable
The device 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 but the device can be controlled in different ways:
●
OUTEN pin. It can be used to control the power sequencing in complex systems.
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 is shorted to SGND in this
condition and protections are disabled except pre-OVP) from any latched condition and
also disables the device keeping all the mosfet turned off to show high impedance to
the load. It can be then cycled to recover from any latched condition such as OVP and
UVP.
●
NOCPU (VID [0;5]=11111x) In this condition (VID5 state is irrelevant) the device is
disabled and keeps all the mosfet turned off to show high impedance to the load.
Nevertheless, it waits for any VID code transition to power up implementing a soft start.
During this condition, SS_END pin is shorted to SGND.
