Power management integrated circuits (PMICs) are crucial components for today\'s electronic products. They help ensure the performance and safety of systems by providing regulated power to the components and monitoring for current, voltage, temperature, and other conditions. Supervisors – also referred to as supervisory circuits – are PMICs specifically designed to protect ICs from damage due to power failures and excessive current or voltage. The TPS3306-25DGKR is a supervisor IC from Texas Instruments that offers a variety of features and can provides a cost-effective and space-saving solution for various applications.

The TPS3306-25DGKR is a power-supply supervisor designed to monitor power supply operation and provide system reset at power-up, power-down, and during abnormal conditions. It is designed to operate with a wide input voltage range of 2.5V to 7.2V and provides a delay time of up to 100ms, programmable in 10ms steps. It can detect both undervoltage and overvoltage conditions and acts to prevent the device from damaging itself due to excessive current or voltage. It also provides an open drain reset output and is available in a 2.4 ✕ 1.4mm TSSOP package for easy integration.

The TPS3306-25DGKR can be used in multiple applications. It is especially useful in designs that require system reset at power-on or underpower conditions. It is also suitable for general-purpose battery-powered systems or those with high start-up current or power surges. As it supports 2.5V to 7.2V input voltage range, the TPS3306-25DGKR can be used in both 3V and 5V systems. It also features an adjustable delay time, which allows designers to adjust the time between applying power and the associated reset, providing extra flexibility in operation.

When it comes to working principle, the TPS3306-25DGKR is designed to detect an undervoltage or overvoltage event, typically within ±10% of the programmed threshold voltage (VDD), and respond by pulling the reset output low. The minimum reset-L pulse width depends on the delay (t_DLY) settings and is typically 500μs with maximum delay, which can be extended to 100ms depending on the particular application requirements. The voltage thresholds for undervoltage and overvoltage can be independently programmed to fit specific application needs, and additional settings such as filter time can also be adjusted. This provides designers with the ability to optimize the reset functionality of their systems.

In summary, the TPS3306-25DGKR is a compact and cost effective supervisor IC with a wide input voltage range, adjustable delay time, and adjustable undervoltage and overvoltage thresholds. It is a great solution for battery-powered applications, those with high start-up current or power surges, and systems that require system reset at power-on or underpower conditions. With its adjustable parameters and easy integration, it can provide protection for electronic systems and ensures that components are kept safe when unexpected power fluctuations occur.
