PMIC - Supervisors

Power Management Integrated Circuits (PMIC) are one of the most influential and pervasive devices that used in any microcontroller unit. PMICs are responsible for preventing unsafe power operations in electronic systems. Supervisors are specific types of PMICs designed for monitoring the state of a powered microcontroller, providing reset signals to system components, and protecting the system from above/below supply voltage and/or bias current levels.

The CAT1025WI-25-GT3 is a unique type of PMIC that is engineered to provide high-performance voltage and current supervision for a variety of applications. This device is composed of three parts: a low-power microcontroller unit (MCU), Voltage Supervisor (VS) with adjustable monitoring thresholds, and Current Supervisor (CS) with adjustable current limits. The MCU is designed to monitor the state of multiple power rails and other system parameters, while the VS and CS provide over-current and over-voltage protection to the device.

Applications

The CAT1025WI-25-GT3 is widely used in a broad range of applications including industrial, military, and automotive systems. In industrial automation and digital control systems, the device is used to monitor voltage and current levels, as well as other system parameters, to ensure safe operation of the power supply. In military and aerospace fields, the device is used to monitor high-power loads to prevent over-current or over-voltage failures. In automotive systems, the device is used to monitor the condition of the automobile battery, providing necessary protection to prevent over-current and over-voltage from occurring.

Working Principle

The CAT1025WI-25-GT3 is designed to monitor the current and voltage levels present on the power rails it is attached to. The device’s MCU is designed to continuously scan the system’s power rails and check for any abnormal current or voltage levels. If any abnormal levels are detected, the device executes an appropriate reset response according to its predetermined settings. The device also provides voltage and current monitoring thresholds that can be adjusted to meet specific application requirements.

The CAT1025WI-25-GT3 also features current limiting circuitry that is designed to prevent over-current in the system. The device continuously monitors the system’s current, and if the output current exceeds the predetermined threshold, it automatically shuts down the power supply or reduces the current until the device is back within the safe current range. This feature helps to protect the system’s components from over-current and over-voltage.

Overall, the CAT1025WI-25-GT3 is an extremely robust and innovative circuit for voltage and current supervision with adjustable monitoring thresholds and current limiting circuitry. The device is designed to provide secure and reliable operation in any electronic system.
