PMIC, or Power Management ICs, are electronic components designed to deliver power to specific areas of an electronic device, such as a camera or a laptop. Supervisors are special-purpose ICs with the sole purpose of monitoring power supplies and related events. These ICs are essential, being able to control the ability to selectively enable and disable individual power rails while providing a variety of services such as monitoring and fault-detection. XC6121C633MR-G is a voltage supervisor specifically designed for use in mobile applications, featuring highly optimized power savings modes, low power dissipation, and integrated fixed and adjustable voltage regulating options.

The XC6121C633MR-G, a supervisor IC from Xilinx, is specifically designed to monitor the system’s main power. It is a CMOS voltage supervisor that provides under-voltage and over-voltage protection in one small package. It has an integrated 8-bit, wide range input and output comparators which can both detect and apply up to 8.5V or down to 2.0V. A 3.3V linear regulator and charge pump enable low voltage on/off control. Active low reset, active high reset and VOFF and VIN control are available as user selectable control pins. This IC also offers a low quiescent current Sleep Mode for optimum power performance.

The XC6121C633MR-G has many applications in mobile systems, from smartphones to tablets. It can be used as a supervisor for the power management circuit, monitoring input voltage and cycling the device in power-down mode if the input voltage is too low. It can also be used to control the on/off states of power rails within a system, switching them off if the voltage falls below a pre-set threshold. It is a low power consumption device, allowing for longer battery life in mobile applications.

In addition, the XC6121C633MR-G can also be used to regulate the power line of a system, by providing a low-dropout linear regulator with a wide range of operating voltages. This can be helpful to ensure that the voltage input is stable, regardless of changes in the input voltage or temperature. It also has a wide temperature range of –40°C to +125°C and an operating frequency range of 200 kHz to 600 kHz, making it suitable for a wide range of applications.

The working principle of the XC6121C633MR-G is relatively simple. It consists of two comparators that detect when the input voltage is either too high or too low. When either of these points is detected, the supervisor signals for the system to shut off if the voltage is too low, or for the system to cycle the power back on if the voltage is too high.

The XC6121C633MR-G is a highly impactful device, providing an efficient and economical solution for mobile applications. It can help extend the battery life of mobile devices by cycling the power off when it detects that the input voltage is too low, and helping to regulate the power which is put in, making sure that it is stable.
