PMIC, or Power Management Integrated Circuit, are integrated circuits (ICs) used to manage the power of embedded systems. They are designed to manage the power states and sequencing of multiple switchable components to ensure supply voltage is appropriate for each condition. One type of PMIC is the Supervisors, which focus on monitoring the power supply and resetting the systems when a critical safe operating condition is breached. One of the products in this field is XC6121F640MR-G.

The XC6121F640MR-G is a low-power voltage monitoring supervisor IC designed for adjustable voltage monitoring and microcontroller reset applications. It is designed to maintain system reliability across a wide supply voltage range, from 0.9V to 5.5V. Its low current consumption makes it ideal for microprocessor and embedded system designs, providing a continuous monitoring of the supply voltage and resetting the system in case of a voltage drop. It is also equipped with an accurate voltage detection circuit with a ±1% detection accuracy.

The XC6121F640MR-G’s operating principle is simple yet reliable. It features a Comparator Circuit with a reference voltage comparator, a Sequence Detection circuit, and a voltage detecting circuit. The Comparator Circuit constantly monitors the voltage level of the power supply to see if it falls below the pre-determined voltage detection level. When the voltage level falls below the set level, the Sequence Detection Circuit will be triggered and generate a reset signal which is then sent to the system. The voltage detecting circuit within the IC will then read the current voltage level, and when the set level is reached the reset signal is cancelled. This ensures that the microcontroller is always in a safe operating condition.

Given its wide voltage detection range, low current consumption and precision voltage reference accuracy, the XC6121F640MR-G is an ideal choice for low power voltage monitoring and reset applications in various embedded systems such as automotive systems, mobile devices and industrial automation control systems. It also features a number of safety and protection features including surge protection, over-voltage protection, under-voltage detection and reverse voltage protection, making it an ideal choice for reliable applications where power steady state needs to be maintained.

The XC6121F640MR-G is a valuable addition to the range of PMIC Supervisors, that provide an effective and accurate solution for low power voltage monitoring and reset applications. By combining a low current consumption, a wide voltage detection range and protection features, it provides reliable protection of the microcontroller and the system while keeping the power consumption low. This makes it an ideal choice for many embedded system applications.
