Introduction

TPS3306-15DRG4 is a high-performance device designed to ensure reliable voltage monitoring and protection functions in power management circuits. It operates based on a coupled comparator architecture, which provides excellent flexibility, high accuracy and fast response time. This device can be used as a supervisor and is most suitable for applications where overvoltage protection features and built-in multiple trip points are essential. This article will discuss the application field and working principle of TPS3306-15DRG4.

Application Field

TPS3306-15DRG4 is suitable for a broad range of applications. It can be used in power supplies, digital power supplies, LED lighting, data acquisition systems, computer systems, embedded systems, battery management systems, and many other applications. The device is able to support multiple voltage levels, providing a wide range of solutions for circuit protection in today’s power management circuits. It also has the ability to detect overvoltage, undervoltage and multiple trip point detection, making it an excellent choice for high safety and reliability.

For medical applications, this device is capable of providing digitally programmable options such as undervoltage detect and reset levels, power-on reset (POR) and output enable features. This helps in delivering a reliable supervision of voltage levels and provides better control over the operation of medical devices. In automotive systems, it can help in monitoring the battery voltage, power on reset and enable/disable operations of the vehicle.

Working Principle

The TPS3306-15DRG4 operates by using a coupled comparator architecture comprising two voltage detectors connected in series. When the voltage level rises beyond the minimum voltage detection (Vdet1) level, the detector will disconnect from the ground and cause the comparator to turn on. When the voltage rises further and reaches the trip point voltage (Vdd), the device will triak and the detector will remain open and the comparator turned off. All these operations are controlled by two detect needles (Vdet1 and V detected2) and a programming voltage bias (Vbias).

The device features various protection features such as the capability to detect overvoltage and undervoltage conditions, multiple trip points, and programmable setpoints. When the device is exposed to overvoltage or undervoltage conditions, it can respond quickly by activating the overvoltage/undervoltage reset pin to prevent any possible damage to the circuits. It also offers a temperature protection feature which ensures safety by detecting high temperature conditions and shutting down the power management circuit to protect it from thermal runaway.

Additionally, the TPS3306-15DRG4 also has built-in low supply voltage detection and the ability to generate an interrupt signal when a specified level is reached. This can be used to implement battery management and power gating functions. Finally, it has an adjustable watchdog timer for detecting, for example, system lockup and responding with a system reset.

Conclusion

In conclusion, the TPS3306-15DRG4 is a reliable and high-performance device designed to provide advanced power management features in various applications. Its coupled comparator architecture and adjustable programming features, along with its overvoltage, undervoltage and multiple trip point detection, make it an excellent choice for demanding applications. Furthermore, its numerous protection features make it suitable for use in a wide range of applications, from medical to automotive.
