JAJSLW7B December 2020 – September 2023 TPS6593-Q1
PRODUCTION DATA
The thermal monitor provides a warning to the host processor through the interrupt system when the temperature reaches within a cautionary range. The threshold value must be set to less than the thermal shutdown threshold.
The integrated thermal warning function provides the MCU an early warning of over-temperature condition. This monitoring system is connected to the interrupt controller and can send an TWARN_INT interrupt when the temperature is higher than the preset threshold. The TPS6593-Q1 device uses the TWARN_LEVEL register bit to set the thermal warning threshold temperature at 130°C or 140°C. There is no hysteresis for the thermal warning level.
When the power-management software triggers an interrupt, immediate action must be taken to reduce the amount of power drawn from the PMIC device (for example, noncritical applications must be closed).
