PMIC (power management integrated circuit) supervisors are often used to monitor the behavior of low-power supplies and provide fault protection for the system. The CAX810JTBI-T3, a member of the XJ family of PMIC supervisors produced by Citek, is an example of one type of supervisor that is used in low power applications such as cell phones, battery powered devices, and digital cameras.

The CAX810JTBI-T3 is designed to provide a highly accurate and reliable power monitoring solution. It combines the functions of a voltage regulator, a power-on reset generator, a power-on reset detector, and a power-on shutoff comparator into a single integrated circuit. This PMIC supervisor is capable of monitoring and regulating multiple voltage rails in the system, including a core logic voltage rail, I/O supply voltages, and other logic and cell level inputs.

The CAX810JTBI-T3 features a wide operating voltage range from 0.9V to 8V, allowing it to be used for both high-voltage and low-voltage applications. It also includes an adjustable voltage regulator with an output voltage range of 0.8V to 8V. The voltage regulator can be programmed to provide a wide variety of output voltages, making it an ideal choice for battery-powered systems.

The CAX810JTBI-T3 also features an adjustable power-on reset Threshold and Window, allowing the user to set the system parameters as needed to ensure proper operation. The Power-on Reset Threshold detects when a voltage output drops below a specified level, while the Window circuitry serves as a backup protective mechanism to ensure power is maintained within a given operational range.

The PMIC supervisor also includes a power-on shutoff comparator, which is designed to provide an interlock between the system shutdown line and a voltage output. This ensures that the output voltage stays within the specified limit, and will prevent the system from exceeding the maximum power dissipation or current flow value.

In addition to its power management functions, the CAX810JTBI-T3 provides comprehensive monitoring and reporting of system health. The supervisor includes an alarm output, which is activated when a voltage output falls outside of its acceptable range. The supervisor can also be used to implement a power-down detection system, which monitors and reports any power-down events, providing a primary system shutoff that is activated when a drop in voltage is detected.

The CAX810JTBI-T3 offers a number of features and benefits that make it an ideal solution for low-power applications. It allows users to monitor and regulate multiple power supplies and provides an efficient way to manage system power. The PMIC supervisor is also an ideal choice for battery-operated systems, as it includes an adjustable voltage regulator and power-on reset Window, allowing users to achieve the necessary voltage levels for optimal performance. In addition, its comprehensive monitoring and reporting functions help users to monitor and report on system health.
