Power management integrated circuits (PMICs) are integrated electronic systems designed to identify, measure, and manage various operating parameters to optimize power consumption in any electronic system. Among these, supervisors are one type of PMICs that monitor power supply voltages and provide reset or interrupt signals when power supply voltages violate specific threshold levels.

The TPS3306-15DG4 is one such supervisor PMIC. It is a low-voltage supervisor designed to supervise and monitor power supply voltages. It is designed for use in systems powered by 3V to 15V voltage rails and features selectable trip and reset thresholds.

In terms of its application field, the TPS3306-15DG4 finds use in automotive power rails and other power systems requiring voltage monitoring, system reset/interrupt, TPI reset, and/or push-button reset. In particular, it is designed to operate over a temperature range of -40°C to +105°C, making it well suited for use in automotive power systems.

As for its working principle, the TPS3306-15DG4 has both trip and reset thresholds that can be individually programmed via the TPS3306-15DG4 device’s resistor network. Once programmed, the device monitors the input voltage and activates its reset/interrupt output when the power supply voltage violates the trip thresholds. The TPS3306-15DG4 also features a push-button reset pin that can be used to reset the system in the event of a failure.

In addition to voltage monitoring, the TPS3306-15DG4 also provides system reset/interrupt, TPI reset, and push-button reset. Its system reset/interrupt feature can be used to reset or immediately interrupt system operations when the power supply voltage violates the trip threshold. Its TPI reset feature allows the device to perform a controlled shutdown of the system when the power supply voltage or temperature violates the trip threshold. Finally, its push-button reset feature allows the system to be reset by a user when the power supply voltage or temperature violates the trip threshold.

Overall, the TPS3306-15DG4 is designed for use in power systems requiring voltage monitoring, system reset/interrupt, TPI reset, and push-button reset. It features selectable trip and reset thresholds and is designed for use in systems powered by 3V to 15V voltage rails. Furthermore, its operating temperature range of -40°C to +105°C makes it well suited for use in automotive power systems.
