PMIC (Power Management Integrated Circuit) supervisors are important components in power management and control tasks. They are used in various systems and applications to maintain accurate behaviour and provide safe and reliable system operations.

TPS3823-25DBVRG4 is one of the available supervisor chips that have become increasingly popular for providing improved protection and reliability for diverse power control applications. This chip provides excellent system protection of the power supply and is therefore suitable for use in complex systems and applications.

This supervisor chip from Texas Instruments has several neat features that help to distinguish it from the rest. These features include excellent flexibility with adjustable threshold settings, wide and adjustable triggering window, output active high/low selection, and programmable current limit settings. The chip also uses a full bandgap reference circuit, has a power on reset, and offers an array of pull-down resistors.

The TPS3823-25DBVRG4 is primarily designed to protect the power supply in a system against a variety of conditions such as overvoltage, undervoltage, and overcurrent. It monitors the power supply and reset outputs in various applications such as microcontrollers, digital signal processors, FPGAs, ASICs, power sequencers, and computers.

When used in an overvoltage application, the chip monitors the voltage at the input and performs an overvoltage shutdown whenever the voltage exceeds the preset threshold voltage. Likewise, when it is used in an undervoltage application, it monitors the supply voltage and triggers an undervoltage shutdown when the supply voltage drops below the predefined threshold. In an overcurrent application, the TPS3823-25DBVRG4 monitors device current and resets the output when the current rises above its programmed threshold.

Another neat feature of this chip is its open drain active-low reset output. This output provides a reset signal to the circuit whenever there is an overvoltage, undervoltage, or overcurrent condition. The reset signal is active until the condition is cleared. The chip also has a debounce circuit, which helps to reduce false triggering of the reset signal.

Because of its excellent flexibility, wide triggering window, and debounce circuit, the TPS3823-25DBVRG4 is an ideal solution for power control applications. Furthermore, it is designed to be a low-cost device, allowing it to be used in a wide range of applications.

In conclusion, the TPS3823-25DBVRG4 is a feature-rich supervisor chip from Texas Instruments that is suitable for a variety of power management and control applications. It offers improved reliability and system protection against overvoltage, undervoltage, and overcurrent conditions. Its adjustable threshold settings and open-drain active-low reset output provide the user with the flexibility to customize its functions for various applications.
