Power management integrated circuits (PMICs) are electronic devices used to manage the power supply of electronic components. They can boost the voltage, reduce the voltage, regulate the current, manage power on-off, or manage temperature. PMICs are made up of many components such as transistors, capacitors, and op-amps, which are responsible for managing the power supply. Apart from PMICs, Supervisors belong to the same class of device and they provide some additional functions, such as protecting the power supply from voltage surges. This article will discuss the application field and working principle of the MIC2772-S2S3YML-TR, a supervisor IC.

The MIC2772-S2S3YML-TR is a two-channel supervisor IC, with single output supply. It features an overshoot protection, as well as active low open drain reset and watchdog output. The reset and watchdog functions are controlled by two independent input signals, and the reset and watchdog thresholds can be programmed using the onboard EEPROM. The IC is designed to operate supply voltages from 1.7V to 5.5V, with a static current consumption of less than 1μA. The IC also features active low open drain reset output, active low reset delay, and active low watchdog output.

The MIC2772-S2S3YML-TR has a wide range of applications in the field of power management and security. It can be used in automotive applications, where overshoot protection is required, and in industrial and medical applications, where accurate monitoring of power supply and temperature is necessary. The IC can also be used in battery-powered systems, where reset and watchdog functions are necessary to ensure reliability, or in high-end computing systems, where overshoot protection and preventative maintenance are required.

The working principle of the MIC2772-S2S3YML-TR is based on two main components: an EEPROM and a voltage monitor. The EEPROM is responsible for storing the reset and watchdog thresholds, and can be programmed using an external programming device. The voltage monitor is then used to detect when the threshold is reached and can trigger the reset, watchdog, or overshoot protection functions. The reset and watchdog outputs are configured using the EEPROM, and the overshoot protection is configured using the external supply voltage.

In conclusion, the MIC2772-S2S3YML-TR is a two-channel supervisor IC, with single output supply. It is used in a range of applications, including automotive and industrial, and is capable of providing reset, watchdog, and overshoot protection. The working principle of the IC is based on the EEPROM and voltage monitor components and is used in a range of applications to ensure reliability and preventative maintenance.
