PMIC (Power Management Integrated Circuit), also known as power supply IC, is a device used to manage the power supply in electronic systems. Supervisory PMICs are used to monitor and control the operating parameters of the power supply, such as voltage, current, temperature, frequency, and power levels. The MIC803-26D4VM3-TR is an example of a supervisor PMIC, and is widely used in commercial, industrial, and consumer applications.

The MIC803-26D4VM3-TR is a high-performance, low-power supervision IC that is designed to protect the power supply system from faults such as overvoltage and overcurrent. It is ideal for 3.3V, 5V, 12.5V, 15V and 24V power supplies, and offers a wide range of options for its output voltages. It has a wide input power range of 5V to 25V, and can be used for both step down and step up regulation.

The IC incorporates a programmable watchdog timer (WDT), clock generator, and over-temperature protection. The WDT monitors the power supply system for any fault conditions, and can be programmed for a wide range of timeout time intervals. The onboard clock generator ensures that the device is synchronized with other system components, and the over-temperature protection prevents the chip from overheating. Additionally, the MIC803-26D4VM3-TR also includes several protection features such as undervoltage lockout and overvoltage lockout.

The MIC803-26D4VM3-TR is widely used in applications such as servers, networking equipment, home automation and industrial control systems, where it is used to protect against power supply faults. It is also used in consumer electronics, such as audio amplifiers, televisions, and gaming consoles. In addition to providing protection against power supply faults, the MIC803-26D4VM3-TR can also be used to provide a stable output voltage and current for the circuit.

The MIC803-26D4VM3-TR works by detecting any fault condition on the power supply and then either resetting the system or triggering the over-temperature protection circuit. When the IC detects an overvoltage condition, it will activate its overvoltage detection circuit and immediately shutdown the power supply. Similarly, when an overcurrent condition is detected, the IC will shut down the power supply to prevent the system from being damaged. Additionally, when an undervoltage or over-temperature condition is detected, the IC will activate its respective protection circuit to prevent system damage.

Overall, the MIC803-26D4VM3-TR is an ideal solution for protecting and monitoring the power supply system from voltage, current, and temperature faults. Its wide range of options and protection features make it a popular choice for commercial, industrial, and consumer applications.
