Power Management Integrated Circuits (PMIC) are integrated circuits that are designed to manage power in certain applications. They manage the power in a circuit by controlling the voltage, current and frequency. Supervisors are a subclass of PMICs specifically designed to protect a device from overloads, over-voltage and over-temperature. One such supervisor is the LM3700XCTPX-296/NOPB by Texas Instruments. This application note will look at its application field and the working principle.

Application Field

The LM3700XCTPX-296/NOPB is a supervisor IC primarily designed for applications that require fast and reliable protection from over-temperature and over-voltage. It is particularly suited for powering low power, portable, battery-operated devices and equipment in environments with extreme temperature ranges. It is a supervisor IC with built-in dual temperature & voltage threshold detection and an interrupt output for warning or triggering an alternate power source.

The LM3700XCTPX-296/NOPB has ultra-fast response time, low noise, and low supply current. It\'s a high-accuracy supervisor IC that detects current, voltage, and temperature signals with a wide detection range and high accuracy. Its system stability is ensured, thanks to its advanced temperature compensation algorithms.

The LM3700XCTPX-296/NOPB is also optimized for low power, low cost, small size and high accuracy. Its small 4.34 mm x 4.16 mm pin-grid array (PGA) package design takes up minimal board space and its high-performance characteristics make it suitable for a wide range of industrial and consumer applications.

Working Principle

The LM3700XCTPX-296/NOPB functions as a temperature and voltage supervisor IC. It protects a device from over voltage and over temperature conditions by monitoring two thresholds – temperature and voltage. It measures the temperature and voltage levels of the system, and then compares them to the previously set thresholds. When either one of the thresholds is exceeded, the supervisor IC triggers an interrupt to warn of an impending power failure or to trigger an alternate power source.

The LM3700XCTPX-296/NOPB is equipped with built-in temperature compensation algorithms which help to keep the system stable by regulating the internal temperature of the IC with an isolated external transistor. This helps to prevent the IC from overheating and causing damage. It\'s designed with a wide detection range to detect voltage and current signals with high accuracy.

Conclusion

The LM3700XCTPX-296/NOPB by Texas Instruments is a high-performance, low power supervisor IC designed specifically to protect a device from over-voltage and over-temperature conditions. It\'s optimized for low power consumption and a small size, making it suitable for portable and battery-operated devices in extreme temperature conditions. It has built-in temperature compensation algorithms which help to keep the system stable, a wide detection range for measure voltage and current signals with high accuracy, and an interrupt output for warning or triggering an alternate power source.
