MIC810JUY-TR

The MIC810JUY-TR is part of a family of supervisor chips designed and manufactured by Micrel Semiconductor. This particular device is a low-voltage supervisor chip intended for use in embedded systems, with an adjustable reset threshold and a built-in delay timer. This integrated circuit has many applications and is commonly used for computer system clocks and a reset input for switching power supplies.

The MIC810JUY-TR belongs to the family of PMIC (power management integrated circuits). PMICs are used to manage power on-board devices to reduce their overall power consumption and provide reliable power supply to their respective components. By eliminating the potentials for short circuits, excessive losses and circuit failures, PMICs ensure the stability, reliability and protection for the system. Supervisors are similar, acting as a "watchdog" that monitors system activity and restarts the system in case of failure or other problems. Supervisors use a clock signal to provide an accurate reference point for data synchronization and system, providing automatic fault detection, reset and/or shutdown in case of errors or system malfunctions, thus further improving system reliability.

The MIC810JUY-TR specifically has an adjustable reset threshold, with the threshold voltage ranging from 2.5V to 5V. It also has a built-in timer to provide a hysteresis margin to prevent latch-up and reduce false trips due to noise glitches. In addition, this supervisor IC also features a low dropout regulator (LDO), which allows it to draw as little as 0.3µA of current in standby mode, making it extremely power efficient. It can be used in a wide variety of systems and applications, including embedded systems, computer clocks, and power supplies.

In terms of its working principle, the MIC810JUY-TR is designed to monitor the voltage level of a system’s power supplies. When the voltage of the power supply reaches a specified threshold (2.5V to 5V), the MIC810JUY-TR will activate a reset signal and inform other components or peripheral devices in the system to enter a safe operating state or to start a process before they reach critical levels. In addition, this supervisory chip can also detect excessive power losses or surges, leading to a safe shut down of the system before further damage to any components can occur.

In summary, the MIC810JUY-TR is a low-voltage supervisor chip intended for use in embedded systems, with an adjustable reset threshold, a built-in delay timer, and an LDO (low dropout) regulator. It belongs to the family of PMICs (power management integrated circuits) and is designed to provide correct system operations, improved protection and power savings. This IC can be used in a variety of applications such as computer clocks and switching power supplies, with its reset signal and automatic fault detection and resetting mechanism providing a reliable and efficient system protection.
