XC6124A443ER-G

Introduction

The XC6124A443ER-G is a Power Management IC (PMIC) specifically designed for the supervision of micro-controllers and digital logic circuits in embedded systems operating at low supply levels of 1.65V to 5.5V. It integrates a wide range of features, from power supply and current monitoring to system reset and watchdog timeout. The XC6124A443ER-G is one of a series of power management ICs (PMICs) designed specifically for the supervision and management of micro-controllers and digital logic circuits in embedded systems.

Application Field

The XC6124A443ER-G is designed to monitor a wide range of inputs, including power-on reset, supply voltage level, temperature, current sense, switch-on reset, system reset and watchdog time-out. The XC6124A443ER-G also provides an integrated voltage regulator, allowing the power supply voltage to be stabilized, eliminating the need for an external regulator. Furthermore, the output of the XC6124A443ER-G can be used to control an external power switch, enabling the device to switch off the device in the event of an over-temperature or over-current condition.The XC6124A443ER-G is designed to be used in applications such as digital logic circuits, micro-controllers, FPGAs and ASICs, data acquisition and switching circuits, communication interface circuits, and automotive systems.

Working Principle

The internal architecture of the XC6124A443ER-G is arranged in two main blocks; the input and control modules, and the output module. The input and control modules are responsible for monitoring the inputs, checking for various conditions such as under-voltage, over-voltage, over-current, over-temperature and switch-on reset. The output module is responsible for controlling the voltage regulator, supplying power to the other components of the system, and providing a power-on reset signal.

The XC6124A443ER-G uses a wide range of sensing and control circuitry to monitor its input sources. These include temperature sensors, voltage reference circuits, current sense circuits, level shifters and comparators. The input and control modules then use these to monitor the external environment, and determine whether to trigger a power-on reset signal, or switch on the voltage regulator.

The output module then supplies power to the other components of the system, and provides the power-on reset signal. Additionally, it is responsible for controlling the voltage regulator, ensuring that the power supply voltage is maintained at the desired level. Finally, the output module also provides a watchdog timeout signal, which resets the system if it is inactive for a certain pre-determined period of time.
