The XC6124C549MR-G is a microcontroller-based supervisory circuit that provides power and reset protection for a range of applications. It enables an improved startup/shutdown and reset sequence for optimal protection of a system’s internal and external components. This circuit is capable of monitoring a wide range of input voltages, with independent monitoring of two adjustable voltage thresholds for signaling an over- and under-voltage condition. This supervisory circuit also provides adjustable reset and power-up timing for the system’s startup, shutdown and reset sequences.

The XC6124C549MR-G features a built-in output buffer, dual programmable reset and power-up delay, and configurable pull-up/pull-down resistors to enable system designers to tailor protection to their specific needs. This supervisory circuit is particularly useful for a range of power management applications, such as microprocessor and microcontroller based systems, where it can be used to determ\ine when power is outside an acceptable range, and to control when a reset should occur in order to maintain system performance.

The XC6124C549MR-G has a wide range of operating voltages, including 1.65V through 6.0V. Its input range can be further extended with voltage buffering. Additionally, it features a low power-up and reset threshold of 1.6V. The internal reset buffer has an output range between 0 and 3.6V, with a built-in level detector to ensure proper operation within the de-24-20V operating range.

The XC6124C549MR-G features adjustable reset and power-up timing, as well as programmable polarity for the reset and power-up signals. It provides two independent voltage set points for monitoring when a reset should be triggered, meaning one set point can be programmed for an over-voltage condition and one for an under-voltage condition. The reset and power-up status is signaled to the system via an open-drain port.

The XC6124C549MR-G also offers a wide range of protection features. For example, it offers a dual window reset with watchdog timer, adjustable window size from 250ms to 128s, and adjustable window refresh. It can be configured to stagger the reset and power-up sequences, enabling a system to be brought up in stages for improved reliability. Additionally, it can be connected to an external 4mA current source, which can reset the microcontroller in the event of a brown out.

The XC6124C549MR-G supervisory circuit is designed to improve system reliability by providing robust over-voltage and under-voltage protection while maintaining system integrity. Its programmable reset and power-up timing and reset threshold adjustment make it an ideal choice for a wide range of advanced power management applications. Its low power design ensures minimal energy usage, while its configurable pull-up/pull-down resistors provide added flexibility for system design. As such, the XC6124C549MR-G is an ideal option for any system requiring superior power management and performance.
