Detailed Description

6.3.11 Enable and Powergood of VRs

The VRs are enabled by the ENVRx pins. The powergood is output on the PGVRx pins. The powergood

pins can be defined as open-drain or push-pull output, depending on the function in order to allow

"ANDing" or to reduce external components and quiescent current. there is a 30-µs deglitch on both edges

of the powergood comparator outputs. A status register monitors the powergood outputs, and the

powergood tree monitors the powergood for proper sequence and protection. The powergood signals can

be masked by a register.
