With the development of technology, the requirement on electronic control systems become higher and higher. PMIC – Supervisors are more and more widely used. A new product, the PT7M7809MTEX, has been developed by Texas Instruments as one of the PMIC – Supervisors. The products will provide a powerful solution for electronic systems.

The PT7M7809MTEX is an innovative product in many aspects, most primarily in its application field and working principle.

Application Field

This product works in a wide range of systems, especially in power supply and communication products, such as wireless and wireline telecom, DVB, CATV, DSL and LAN as well as DC-DC power supply. This product can be used in AC/DC converters, DC/DC converters and generation-I PMICs.

It can be used in the application field of AC/DC regulators, DC/DC regulators, generation-II PMICs, power supply and voltage detection applications, as well as current monitoring applications. It also offers CPU protection, over-voltage protection, over-current protection, short circuit protection and temperature sensing.

Working Principle

The PT7M7809MTEX is designed to provide powerful protection features in order to secure the target application against possible rail decoupling events by monitoring the user-defined rails. First of all, the product monitor the supply voltage of the rail and compare it with both the upper/lower thresholds, that can be set with on-chip configuration registers. When the power supply rail of the application is over-voltage or under-voltage, then the product can trigger an alarm signal to alert or to provide auto-shutdown control for the system.

Another application of the PT7M7809MTEX is to monitor the current of the rail and compare it with the user-defined threshold. When the rail reaches the upper/lower threshold, then the product will trigger an alarm signal to alert or to provide auto-shutdown control for the system.

Moreover, it can be applied in temperature sensing. Under certain temperature level, the product will automatically turn off the power supply. This will make the system more reliable and safe.

In addition to all of the application field mentioned above, The PT7M7809MTEX is a powerful tool for protecting and optimizing the performance of various applications. This product will bring accuracy and cost reduction to the target systems.

Conclusion

The PT7M7809MTEX is a powerful product for protecting and optimizing the performance of various applications. It offers various application fields and various working principles, such as AC/DC regulators, DC/DC regulators, generation-II PMICs, power supply, voltage detection, current monitoring, CPU protection, over-voltage/over-current protection, short circuit protection and temperature sensing, which guarantee the accuracy and reliability of the target systems.
