PMIC - Supervisors

The MIC706SM-TR is a supervisor device that combines a microprocessor-reset and supply monitor device. It is an integrated circuit that is used to protect a microprocessor from unwanted activity, and is typically used in personal computers and other electronic equipment. Its primary function is to monitor the supply voltage and detect any conditions that could be harmful to the microprocessor and other components.

The MIC706SM-TR\'s application field includes computers, gaming consoles, digital home entertainment systems, automotive switching systems, telecom lines, and medical instruments. It is also suited for use in networking and storage systems, power supplies, and industrial control applications. The MIC706SM-TR has the capability to detect under-voltage and over-voltage events, detect open and shorted supplies, add auto-reset (after a specified time), detect manual-reset events, and perform brown-out and power-fail events.

Working Principle of MIC706SM-TR

The MIC706SM-TR is an external monitoring supervisor device, which monitors the power-supply voltage and executes the necessary functions if a fault is detected. It monitors the power-supply voltage by measuring the voltage level at predetermined intervals and triggering an interrupt if the voltage drops below or rises above the preset levels. The MIC706SM-TR also detects overload conditions, such as current spikes, transients, or overloads that could damage the microprocessor.

The MIC706SM-TR contains several pins that help to control and monitor the system functions. These include a reset input, which can be activated by the processor to reset the system when the voltage drops below or rises above the preset levels; a VCC supply voltage input, which is used to monitor the voltage level of the processor supply voltage; and two output pins, which report the status of the system either to the processor or to other components in the system.

The MIC706SM-TR also includes a reset timer, which can be programmed to delay the reset if the voltage drops below or rises above the preset levels. This is important as it provides a margin of time for the system to respond before the reset occurs. This timer can also be used to provide a timeout period in case the processor is stuck in a certain state.

The MIC706SM-TR is a versatile device that can be used to detect various scenarios involving power-supply voltage and voltage-related issues. It can be used to provide a safe and reliable power-supply environment, to protect against current-sourcing or overloads, or to detect open or shorted supplies. Additionally, it can be used to detect manual-reset events and to report the status of the system.
