I2C Write Access Multiple Bytes Figure 6-10. I2C Read Access Multiple Bytes 6.11 Thermal Monitoring and Shutdown A thermal protection module monitors the junction temperature of the device versus two thresholds: • Hot-die temperature threshold • Thermal shutdown temperature threshold When the hot-die temperature threshold is reached, an interrupt is sent to software to close the noncritical running tasks. When the thermal shutdown temperature threshold is reached, the TPS65911x device is set under reset and a transition to OFF state is initiated. Then the POWER ON enable conditions of the device are not considered until the die temperature has decreased below the hot-die threshold. Hysteresis is applied to the hot-die and shutdown thresholds, when detecting a falling edge of temperature, and both detections are debounced to avoid any parasitic detection. The TPS65911x device allows programming of four hot-die temperature thresholds to increase the flexibility of the system. By default, the thermal protection is enabled in ACTIVE state, but can be disabled through programming the THERM_REG register. The thermal protection can be enabled in SLEEP state programming the SLEEP_KEEP_RES_ON register. The thermal protection is automatically enabled during an OFF-to- ACTIVE state transition and is kept enabled in OFF state after a switch-off sequence caused by a thermal shutdown event. Transition to OFF state sequence caused by a thermal shutdown event is highlighted in the INT_STS_REG status register. Recovery from this OFF state is initiated (switch-on sequence) when the die temperature falls below the hot-die temperature threshold. Hot-die and thermal shutdown temperature threshold detection states can be monitored or masked by reading or programming the THERM_REG register. The hot-die interrupt can be masked by programming the INT_MSK_REG register. 6.12 Interrupts Table 6-5. Interrupt Sources Interrupt Description RTC_ALARM_IT RTC alarm event: Occurs at programmed determinate date and time (running in ACTIVE, OFF, and SLEEP state, default inactive) RTC_PERIOD_IT RTC periodic event: Occurs at programmed regular period of time (every second or minute) (running in ACTIVE, OFF, and SLEEP state, default inactive) |
