MAX809SQ293T1G General Description

The MAX809SQ293T1G is a microprocessor supervisory circuit manufactured by ON Semiconductor. It is designed to monitor the power supply voltage of microcontrollers, microprocessors, and other digital systems to ensure their proper operation.This device has a voltage detection threshold of 2.93V, which means it will trigger a reset signal when the supply voltage drops below this level. This helps prevent the system from operating incorrectly or crashing due to insufficient power supply.The MAX809SQ293T1G features a low quiescent current of only 4μA, making it suitable for power-sensitive applications where energy efficiency is a priority. Its small form factor and low power consumption also make it ideal for battery-powered devices.In addition, this supervisory circuit has a manual reset input that allows for external control of the reset signal. This feature can be useful for testing and debugging purposes.
