Overview
The MAX809SN160T1 is a microprocessor reset monitor produced by ON Semiconductor. It is part of the MAX809 series, designed to monitor the supply voltage (VCC) in digital systems and provide a reset signal to the host processor when necessary. This device is particularly suited for battery-powered applications due to its very low supply current of 0.5 μA at VCC = 3.2 V. The MAX809SN160T1 features an active-low RESET output and is available in a compact SOT-23 package.
