The MAX6328UR31+T from Analog Devices (formerly Maxim Integrated) is a microprocessor (µP) supervisory circuit that monitors power supply voltages in µP and digital systems. It provides reliable power supply monitoring by asserting a reset signal when the VCC supply voltage drops below a preset threshold, maintaining the reset for at least 100ms after VCC rises above the threshold.
Key features include an ultra-low supply current of 1µA (max) for the MAX6326/MAX6327/MAX6328 series, making it suitable for portable equipment. The device offers precision monitoring of 2.5V, 3V, 3.3V, and 5V power-supply voltages, with reset thresholds available from 2.2V to 4.63V. It is fully specified over temperature and provides power-supply transient immunity without requiring external components.
This supervisory circuit is available in space-saving SC70 and SOT23 packages. The MAX6328 series features an open-drain, active-low reset output. All devices are guaranteed to be in the correct state for VCC down to 1V. The reset comparator is designed to ignore fast transients on VCC.
