PMIC - Supervisors

PMIC Supervisors are integrated circuits that provide advanced temperature and voltage monitoring features, typically found in most embedded systems with microprocessors or microcontrollers. They provide a wide range of features, from basic reset control to complex multi-level event control. The TPS3306-20QDRG4Q1 device is a good example of a PMIC Supervisor.

Application Field

The TPS3306-20QDRG4Q1 is capable of providing protection to a wide variety of embedded systems, such as automotive, industrial, and consumer applications. This device can be used to monitor, indicate, and reset the system voltage. It offers protection against power supply problems, such as surges, overvoltage, and undervoltage conditions. It also monitors system temperature and can provide protection against over-temperature conditions. This device is capable of resetting the system in the event of a voltage or temperature emergency.

Working Principle

The TPS3306-20QDRG4Q1 has a wide input voltage range of 2.7V to 5.5V, allowing it to be used in most common microcontroller applications. The device is capable of monitoring both the system voltage and temperature, and can provide reset protection if either of these conditions exceeds a pre-set threshold. The device also has an enable and active reset output which allows the system to perform a reset if the voltage or temperature exceeds an acceptable level. The enable and active reset outputs are used to alert the system of a problem, and drive the appropriate reset signals to bring the system back to a normal state.

Additionally, the device can be configured for dual-rail power supplies. This allows the device to monitor both the positive and negative supply rails, as well as detect and react to fault states on both rails. By monitoring both these rails the device can ensure a safe, stable operation for the system.

The TPS3306-20QDRG4Q1 also has auto-restart and watchdog timer features which can be used to reset the system in the event of an unexpected fault. The watchdog timer allows the device to be periodically checked and reset a system if a problem has been detected. The auto-restart feature allows the device to automatically reset the system after a power failure or short duration over-temperature issue. This allows the system to quickly return to normal operations in the event of any critical conditions.

Conclusion

The TPS3306-20QDRG4Q1 is a versatile PMIC Supervisor that can be used in a variety of applications. It provides advanced protection against voltage and temperature related issues, and provides a wide range of features such as auto-restart, watchdog timer, and dual-rail power supply monitoring. This makes it an ideal solution for embedded systems which require accurate and reliable voltage and temperature monitoring.
