PMIC – Supervisors are a special class of Integrated Circuit (IC) which is primarily used to enforce multiple output voltage rails in order to maintain optimum performance of the microprocessor integrated circuits. They can also be used to monitor the voltage levels on the microprocessor, detect faults in the system, and provide protection against overvoltage, inrush current, too-high temperatures, and other fault conditions. The MIC803-41D3VC3-TR Power Management Integrated Circuit (PMIC)is a part of this class of ICs and is used for a wide range of applications.

Specifically, the MIC803-41D3VC3-TR IC is commonly used for Programmable System on Chip (SoC) designs, general-purpose monitoring and protective applications. Its main features are low power reset/supervisor functions, an adjustable reset threshold, and a monitor & comparator functions with adjustable voltage thresholds. The MIC803-41D3VC3-TR IC is ideal for use with a wide range of 3.3 V & 5V processor operating manufactures due to its low power reset/supervisor functions and multiple voltage threshold monitoring.

The MIC803-41D3VC3-TR IC’s typical application field includes SoC monitoring, power on reset and power fail sensing. In the case of SoC monitoring, the IC monitors the voltage in the processors, and can detect any voltage drop below the pre-defined thresholds. When the monitored voltage falls out of the pre-defined window, a reset signal is triggered, thereby resetting the processor and allowing it to function as normal. This prevent any erroneous system behavior and allows the processor to continue to operate within its normal parameters.

The power on reset is another application in which the MIC803-41D3VC3-TR IC is used. This feature allows the IC to detect when the supply voltage has been applied and reset the system so it can begin normal operation. The IC has a delay of up to 10 ms before the reset signal is triggered, allowing the processor to fully boot up without any interruption. This ensures a smooth start-up procedure for any system.

Finally, the MIC803-41D3VC3-TR IC also has a power fail sensing feature which is used for detecting sudden voltage drops below a certain preset threshold. If a power drop is detected, the IC immediately sends a reset signal so the processor can reset itself and perform the respective operations, such as closing open files, saving data and powering down peripherals.

The MIC803-41D3VC3-TR IC operates using two main main principles. The first is by detecting voltage differences between the minimum and maximum threshold levels which have been configured on the device. When the monitored voltage deviates from these set thresholds, a reset signal is triggered. The second principle is by continuously monitoring the supply voltage while the system is on and providing a reset signal when any drop in voltage is detected. This reset signal is triggered regardless of whether the voltage change is within the configured threshold or not.

The MIC803-41D3VC3-TR IC is a low power, highly integrated PMIC which offers excellent performance and cost effectiveness. Its various features make the IC suitable for applications which require monitoring and protection functions. Its configurable reset and monitoring thresholds which can be adjusted to suit the required voltage levels and varying power rail requirements makes it perfect for use in a wide range of SoC designs and general-purpose monitoring and protection applications.
