PMIC - Supervisors

The XC6124A536MR-G is a supervisor designed with a 6.5mm x 6.5mm square body and surface-mounted. It is able to monitor the voltage values in the system within the 0 to 5.5V voltage range and apply reset function when system voltage drops below the threshold level. This supervisor also features an accurate threshold detection point, ensuring that the reset happens within a stable and reliable margin.

Besides reset, this XC6124A536MR-G also provides brown-out detection, power-fail detection, and watch dog timer functions. With the brown-out detection, once any of the voltages monitored has dropped below the allowable threshold, a low-level output signal will be generated which can used for brown-out reset. The power-fail detectionfeature, on the other hand, is able to detect any voltage abnormality in the system. This allows the supervisor to generate an output signal for system shut-down. Finally, the watch dog timer function can be utilized to ensure system stability by regularly resetting the system if it does not respond in specific time frames.

The XC6124A536MR-G plays an important role in electronic systems, as it acts as an ‘invisible hand’ to monitor the system and take action when necessary. Primarily, it is utilized in electronic systems that are sensitive to voltage fluctuation or require constant voltage, such as servers, industrial systems, and embedded systems. In servers and industrial systems, the supervisor helps to maximize system longevity and reduce the possibility of system corruption due to voltage fluctuation. In embedded systems, the supervisor works as an effective fail-safe against reset-related problems which may threaten system stability.

The XC6124A536MR-G has a positive-edge-triggered watchdog timer that has an integrated logic circuit to monitor the internal circuit state and generate reset output. The timeout period for the watchdog timer is programmable and is available in cycles of 1.6, 3.2, 6.4, 32, and 64 seconds. The reset output is also equipped with an open-drain structure that allows multiple devices to be reset simultaneously.

Power-down detection feature is also built into this supervisor. When the power-down voltage drops below the predetermined voltage, a power-down interrupt is generated to notify the system that the voltage has dropped so that the system can take appropriate action to protect itself. This is particularly useful for applications that need to protect itself from power surges or outages.

The XC6124A536MR-G is designed with an input voltage of 5V, allowing it to be adaptable to a range of systems. It has a maximum standby current draw of 300nA at 3V and operates at a temperature range of -40°C to +125°C. This supervisor is an excellent solution for anyone looking for a reliable, accurate and cost-effective way to protect their systems from voltage fluctuation and power-related problems.
