ZHCSIF5F December 2015 – April 2019 TPS99000-Q1
PRODUCTION DATA.
The TPS99000-Q1 contains two on-chip die temperature monitors, for reduncy purposes, to monitor the internal temperature of the TPS99000-Q1. Each monitor has an output that indicates whether the die temperature has exceeded one of two thresholds. One monitors a warning threshold, and the other monitors an over-tempreature error threshold. If the warning threshold is exceeded, a processor interrupt may be generated. If the over-temperature error threshold is exceeded during operation, the TPS99000-Q1 will initiate an emergency shutdown procedure and then wait for a toggle of the PROJ_ON pin to initiate a system restart while operating in a low power state. The system will not proceed through the power on initialization steps unless the on die temperature is below the warning threshold. The status of these temperature monitor output bits is available over the SPI buses as long as DVDD and VDD_IO power supplies are up and stable.
