XC6123D716MR-G

Introduction

The XC6123D716MR-G is a preventive maintenance and control (PMC) part designed to monitor and regulate the operation of real-time systems and data acquisition applications. Developed by STMicroelectronics, the XC6123D716MR-G provides a high level of power management, safety and error detection for a variety of industrial and consumer uses. Specifically, the XC6123D716MR-G is a supervisor and power-on reset (POR) circuit that is used in systems that need to undergo frequent or unpredictable changes in power levels and maintain reliable operation.

Application Fields and Working Principle

The XC6123D716MR-G has a wide range of applications, including but not limited to: embedded systems, telecommunications, test and measurement equipment, data acquisition, portable devices, home audio/video systems, power supplies and other power management circuits. The XC6123D716MR-G is a supervisor with an operational power supply range from −25V to +12.6V and features a high-accuracy voltage detector with a user-programmable threshold, an internal reset time-out, power-on reset (POR), pushbutton reset (PSR) and adjustable delay times.In order to operate, the XC6123D716MR-G requires an external adjustable power supply for the reset circuit. It typically connects to the main supply rails and continuously monitors the output voltage to provide a robust power management solution. The externally adjustable power supply ensures reliable operation even during periods of power surge or dropout. Additionally, the XC6123D716MR-G can also be used to detect a number of fault conditions, such as overheating, short-circuiting, and over-voltage, and then to trigger a reset to protect the system.For maximum performance, the XC6123D716MR-G utilizes a built-in multiplexed voltage critical feature that provides an adjustable reset threshold and hysterisis, allowing the user to adjust the time-out period and electric thresholds for reset activation. The Voltage Sensing, Reset and Reset Enable pins are connected via the external adjustable power supply with programmable threshold/hysterisis and can be programmed to trigger a reset if predetermined current flows are detected.

Features

The XC6123D716MR-G is a high-performance PMIC with a variety of features and capabilities. In addition to the previously discussed Voltage Sensing, Reset and Reset Enable functions, the XC6123D716MR-G includes:
