Introduction

Power Management Integrated Circuits (PMICs) are an important part of many electronic systems, providing the power management backbone for product designs. Responsible for tasks including power sequencing and sequencing, virtualizing, monitoring recordkeeping and system fault detection, PMICs play a critical role in many power subsystems. This article will introduce the PMIC- Supervisors field and also cover the working principle of a particular type – the TCM809RVLB713.

PMIC-Supervisors Overview

PMIC- Supervisors are a type of PMIC that provide system fault protection and monitoring, ensuring a safe and stable power source is available to the system. In some cases they also provide advanced features such as wireless and optical sensor monitoring.PMIC- Supervisors are designed to monitor voltage levels, current flows, and temperature, providing an alert if any of these values exceed a predetermined range or fail to meet set parameters. In addition, they perform system fault detection and offer advanced features such as soft reset and programmable voltage, current, and temperature thresholds for greater control. In terms of applications, PMIC- Supervisors are most frequently used in appliances, consumer electronics, automotive, industrial and military applications, though they can be found in any application that requires monitoring or system fault protection.

TCM809RVLB713 Overview and Working Principle

The TCM809RVLB713 is a fully featured PMIC- Supervisor manufactured by Texas Instruments. It is a powerful and robust device, designed to provide advanced system protection, fault detection and monitoring. The TCM809RVLB713 monitors system faults, including overvoltage, overcurrent, and overtemperature faults. It is designed to provide protection to all power loads in the system. The TCM809RVLB713 supports voltage, current, and temperature thresholds that are adjustable through an I2C serial bus interface. The device is also capable of providing an interrupt to the processor to indicate a pending fault. The TCM809RVLB713 is compatible with 2.7 to 5.25V power inputs, making it suitable for use in a variety of applications. Its wide range of features and low power stand-by mode also make it ideal for battery powered or low power applications. In terms of fault protection, the TCM809RVLB713 relies on a combination of undervoltage and overvoltage protection. Undervoltage protection (UV) detects when an input voltage drops below a predefined level, and the device will then trigger a reset or an interrupt. Similarly, overvoltage protection (OV) detects if an input voltage rises above a predefined level, and again the device will trigger a reset or an interrupt.The TCM809RVLB713 also features current monitoring, which monitors and detects when a current exceeds a preset threshold. This is done by measuring the voltage drop across an external sense resistor and converting it to a current condition. The device is also capable of monitoring temperature levels, allowing it to detect and prevent system overheating.

Conclusion

PMIC- Supervisors are an important type of PMIC, capable of providing system protection and monitoring in a range of applications. They ensure maximum efficiency and reliability, leading to improved system performance and longevity. One example of a PMIC- Supervisor is the TCM809RVLB713 from Texas Instruments. This device provides advanced system protection, fault detection and monitoring, operating in a wide range of applications including consumer electronics, automotive and military applications.
