Power management integrated circuits (PMICs) are designed to monitor and control power systems and allow for the efficient use of energy within different digital applications. In order to maintain stable working conditions for digital systems, PMICs offer a range of options for regulating and monitoring voltages, currents and power levels. One of the most important functions of a PMIC is to provide protection for the applications it is powering. Supervisors are a type of PMIC that provides this protection from voltage, current, or temperature transients.

TPS3106E09DBVR is a supervisor device from Texas Instruments that integrates voltage monitoring with an overvoltage, undervoltage and over-current protection. This device is specifically designed for use in portable battery-powered applications such as mobile handsets and PDAs. The TPS3106E09DBVR offers a wide operating voltage range of 2.5V to 5.5V, making it ideal for a wide range of portable application.

The TPS3106E09DBVR has several key features that make it suitable for use in portable battery applications. It offers low quiescent current, which makes it highly efficient. This low quiescent current also makes it ideal for applications with limited power budgets, such as those powered by a single battery cell. Additionally, it has an internal voltage reference, which means that the monitored voltage is always adjustable and independent of the supply voltage. It also has shutdown and power-on reset functionality, ensuring that power is cycled in a controlled, predictable manner.

The TPS3106E09DBVR also includes a variety of protection features. This device features built-in overvoltage, undervoltage, and over-current protection that can be adjusted by setting appropriate trip and reset thresholds. This allows for a wide range of applications from basic supervised power supplies to highly sophisticated applications with different levels of protection tailored to the system level.

The TPS3106E09DBVR works by monitoring the supply voltage and output current of the system. If the supply voltage or current rises above the set trip threshold, the device trips and shuts down the system. The device will then wait for the voltage or current to fall below the reset threshold, allowing it to re-energize and start the system up again. This feature ensures that the system remains stable and does not experience any sudden power outages.

In summary, TPS3106E09DBVR is a low quiescent current supervisor device suitable for use in portable battery applications. It features a wide operating voltage range and adjustable overvoltage, undervoltage, and over-current protection. These features make the TPS3106E09DBVR an ideal choice for battery-powered devices that require a highly efficient and reliable supervisor.
