Power management integrated circuits (PMIC) are an essential component in the electronic circuits. They help maintain power supply, allow power savings and regulate power to protect the circuit from various physical and logical damages due to power failure. Supervisors are a type of PMICs and XC6124D521MR-G is a popular supervisor from the XC6124D supervisory family. It can be used for a range of applications, from line activation to reset generation, providing functional benefits that range from improved circuit noise immunity to better product reliability.

Application Field

The XC6124D521MR-G is designed for application in various system designs where a reset functionality is needed. It is a versatile product that is suitable for any application where reset is required, starting from embedded systems, microcontrollers, field-programmable gate arrays (FPGAs) to digital signal processors (DSPs). These reset functions include manual resets, watchdog timer resets, low power reset and soft reset protection. All of these reset functions are also available in both level-sensitive and edge-sensitive options.

It is also suitable for use in consumer and commercial circuit applications where power savings and improved system performance is desired. It can be used for voltage monitoring, reset protection and power fail applications. The device also has integrated circuit temperature monitoring, enabling system temperature control and control of other external components.

Working Principle

The working principle of the XC6124D521MR-G is based on the concept of reset generation. When the reset condition is detected, the supervisor latch-up and triggers a reset pulse, which can be used to reset a part of the system or an entire system. This reset pulse is triggered by a voltage threshold, or an active edge or low-level drop on the output, which is known as the RESET or RESETB pin. The pulse width of the reset pulse can be configured between 10ms and 200ms, allowing flexible design implementation.

In addition to reset generation, the XC6124D521MR-G also provides enhanced features including voltage monitor, power fail protection and circuit temperature monitoring. The voltage monitor feature monitors the device\'s various system voltages and triggers a reset pulse when it falls below a certain level. This feature is useful for protecting sensitive circuitry against power failures due to overcurrent, voltage glitches and other effects. The power fail protection feature monitors the power supply of the system, preventing any power issues from occurring.

The XC6124D521MR-G also includes a circuit temperature monitoring feature. This feature monitors the temperature of the device and triggers a reset pulse when the device reaches a certain temperature level. This feature is useful for controlling external components and providing additional protection against thermal damage.

The XC6124D521MR-G also provides a watchdog timer reset feature. This feature is used to detect system freezing or stalling due to erroneous code running or hardware errors. When the watchdog timer expires, it triggers a reset pulse to reset the system, allowing the system to run reliably without interruption.

The XC6124D521MR-G is an ideal solution for providing reset and power fail protection for a variety of applications. Its integrated features provide enhanced reliability and power savings for a number of system designs. With its multiple reset cases, voltage monitoring and other features, it is a flexible and versatile PMIC with a wide range of use cases.
