PMIC (Power Management Integrated Circuits) are a range of power controllers that are placed in electronic devices to manage the power flow of electricity and distribute it to the various components of electronic products. Supervisors are circuits that are used to monitor the stability of voltage and current supply to electronic products. The MAX16125WTCS16+T is a power monitor and supervisor IC which is being used in a wide range of PMIC applications.

The MAX16125WTCS16+T is an integrated circuit supervisor with built-in high combination of accuracy and resolution for monitoring the power supply. It has an adjustable voltage and current threshold of 1.25V and 16mA respectively with an accuracy of 0.2%. It incorporates a dual-channel comparator for detection of under-and over-voltage conditions and can shut down the system in case of abnormal conditions like short circuit or over-temperature. It has an integrated temperature sensor to protect against thermal events.

The MAX16125WTCS16+T has two voltage and current pins for monitoring, two general-purpose inputs for additional fault-conditions monitoring and one output pin for driving the alerts and reset. It also has a 2-wire serial interface to allow reading of monitoring and configuration register values. The MAX16125WTCS16+T includes a built-in 5ms timer to allow system reset after a fault condition has been met. The MAX16125WTCS16+T is available in a 16-pin SSOP package.

The MAX16125WTCS16+T is an ideal solution for applications such as power management systems, power supply supervision, and power over Ethernet systems. It can also be used for testing and monitoring of the power supply of consumer electronics, industrial equipment, and automotive applications. The MAX16125WTCS16+T provides accurate, comprehensive, and cost-effective monitoring of the power supply monitoring.

The working principle of MAX16125WTCS16+T is based on voltage and current threshold monitoring. It has two voltage monitor pins that monitor the input and output voltages. Likewise, it has two current monitor pins that measure the input and output currents. The sensors on the MAX16125WTCS16+T sample the input and output voltages and currents and compare them against the programmed threshold values. When the measured voltages and currents exceed the programmed thresholds, the MAX16125WTCS16+T automatically shuts down the system in order to protect the electronic components.

The MAX16125WTCS16+T also has two general-purpose inputs that can monitor additional fault conditions such as over-temperature and short-circuits. The MAX16125WTCS16+T has a 2-wire serial interface which can be used to read the monitoring and configuration register values. The integrated temperature sensor monitors the temperature of the system and triggers system shutdown if it exceeds the maximum temperature threshold.

The MAX16125WTCS16+T has a built-in 5 MHz oscillator for providing a clock for communication interface. It also has an integrated watchdog timer to ensure the system is reset after a fault condition is met. In addition, the MAX16125WTCS16+T has a non-volatile memory which stores the registers and settings over power cycle. The MAX16125WTCS16+T can be programmed for one-shot or periodic measurements, enabling continuous monitoring of power supply.

In summary, the MAX16125WTCS16+T is a power monitor and supervisor IC that provides accurate monitoring of the power supply and protection against under-and over-voltage faults. It has integrated temperature sensing, general-purpose inputs and 5ms timer to prevent the system from resetting during fault conditions. The MAX16125WTCS16+T is an ideal solution for a wide range of PMIC applications.
