PMIC - Supervisors are specially designed devices which are used to ensure the correct operation of a microcontroller and prevent it from entering an indeterminable state which occurs due to power supply problems, system faults or non-optimal settings of the microcontroller.

The MIC1810-5U-TR is one of the most commonly used devices on the market for this purpose. It is a small and low-cost 5V supervisor that monitors power and provide a highly reliable system reset if power drops below the defined threshold. The device is upgraded to the chipMIC1810-5U-TL variant, which includes additional features such as adjustable reset active period, selectable reset active voltage(s) and an optional active reset output.

As one of the most popular supervisors among embedded system designers and engineers, the MIC1810-5U-TR device has some unique features that make it more functional and useful in a variety of applications. It features a very low quiescent current of only 2 μA, which makes the device suitable for the most power-sensitive systems. As well as the MIC1810-5U-TR also has a very low start-up current of typically 7 μA which helps to ensure that the system will start in expected time.

The MIC1810-5U-TR provides an active reset output that is asserted if the system does not recover from a detected fault event within a certain period of time. This is done to prevent damage or undesired behaviour in the system. The reset period is adjustable from 5ms to 32s so the designer can choose the best configuration for the target system. Additionally the device has an adjustable reset active voltage from 1.8V to 5.0V, so users can optimize the device to achieve the best reset timing.

The MIC1810-5U-TR is also very reliable, due to its redundant reset system. Even if one of the reset circuits fails, the other circuitry is capable of keeping the system stable and operational. This feature significantly improves the long-term stability of the system and allows it to operate efficiently for years.

In summary, the MIC1810-5U-TR is a flexible and reliable low cost 5V supervisor which is suitable for a wide range of applications. It has a variety of features such as low-quiescent current, low start-up current, adjustable reset active period and voltage, and redundant reset system. This makes the device particularly useful for embedded systems required to operate in a wide range of power supply conditions.
