Power management integrated circuits (PMIC) are a vital part of all modern electronic systems, as they are responsible for efficiently converting, regulating, and distributing power to the electronics within a system, allowing them to function reliably. One particular type of PMIC - supervisors - are designed to monitor system functions and alert the user when certain conditions are met. The LTC2909CTS8-5#TRPBF is an example of such a supervisor, capable of synchronized monitoring of high-side, low-side, and other voltages. In this article, we will examine its application field and working principle.

Application Field

The LTC2909CTS8-5#TRPBF is suitable for a number of applications, including mil-aero, telecom, automotive, industrial, and consumer applications. It is especially well-suited to applications that require high levels of reliability, such as those operating in strict compliance with DO-254 certification standards. Additionally, it is designed for applications that require monitoring and control of high-side, low-side, and other voltages, as well as control of alarm signals when certain conditions are met.

Function and Principle

The LTC2909CTS8-5#TRPBF is a supervisor-style PMIC intended for use in applications that require monitoring and control of high-side and low-side voltage inputs. It supports alarm outputs when programmed thresholds are exceeded. Additionally, it offers both supply-rail and line monitor diagnostic interfaces, allowing for the detection of voltage drops, over-voltages, and other conditions. It has an integrated dead-time and frequency generator, further enhancing the reliability of the supervisor by providing pre-programmed settings for best-in-class performance.

The device utilizes a proprietary algorithm to monitor multiple voltage sources such as the main power rail, LVD under-voltage, and over-voltage. An adjustable timing circuit allows for customization of the delay times as required. Additionally, it is equipped with a three-state open-drain shadow latch output, indicating when one or more monitored conditions are not within predetermined thresholds, allowing the user to take swift action when alerted.

Conclusion

The LTC2909CTS8-5#TRPBF is a PMIC supervisor tailored for applications that require monitoring and control of high-side, low-side, and other voltages, as well as control of alarm signals when certain conditions are met. It supports a wide range of applications, particularly those requiring strict compliance with DO-254 standards, and offers features such as a supply-rail and line monitor diagnostic interface, adjustable dead-time, and frequency generator for enhanced reliability.
