ADM692SQ is a low-voltage supervisor designed to monitor system conditions of three-terminal regulators and other tRACtive supplies. It is a PMIC (Power Management Integrated Circuit) Supervisors device and provides effective protection to other system components, like memory and microprocessor, by monitoring and responding to power supply faults.

The basic function of the ADM692SQ is to monitor power supply voltages and control a reset circuit to reset the system if under and over-voltage conditions occur. It is typically used in applications where there is variable power supply circuitry, or where it\'s necessary to protect from destructive over-current conditions, like printing systems, motor drives, and recorders.

ADM692SQ features an on-board voltage reference which allows for a precise voltage threshold for reset and a wide operating temperature range of -40℃ to +85℃. It also features an active-low reset output, an open-drain output, and an active low CMOS active-low power-on reset (POR) output to provide signals to an external reset circuit.

At the heart of the ADM692SQ is its on-board comparator, which constantly monitors the system supply voltage and compares it to the reference voltage generated by the on-board voltage reference. When the device senses an overvoltage condition, the reset signal is pulled down and the external reset circuit is activated. When the voltage reaches a stable condition again, the reset output is released and the device will remain in normal operation.

The ADM692SQ is an efficient and reliable PMIC Supervisor for a wide range of applications. It can be used in an automotive environment or in industrial control applications. It is available in a 5-pin SOT-23 package and provides effective protection for system components. It is a precision monitoring device and it is programmable using an external resistor to adjust the voltage threshold.

In summary, the ADM692SQ is a fast, versatile and accurate PMIC Supervisor device designed to protect other components from voltage over-voltage and under-voltage conditions. Its on-board voltage reference provide precise voltage monitoring, while its wide operating temperature range and active-low reset outputs make it suitable for a wide range of applications.
