The MAX6327XR23+T is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2V to 5.5V and features an active-high, push-pull reset output. The device monitors one input with a fixed threshold voltage of 2.32V. It consumes a maximum operating supply current of 1µA. The reset delay time is specified at 100ms minimum. The component is housed in a SC-70-3 package and supports surface mount installation. It functions reliably across an industrial temperature range from -40°C to +85°C.
Verify the specific suffix designation against official manufacturer documentation to confirm exact threshold voltage and package variant. Confirm RoHS compliance status through certified datasheets. Check current availability as distribution channels may list limited stock or end-of-life statuses. Ensure the ordering part number matches the required electrical characteristics for your specific application design.
Select this component when an active-high reset signal is required for systems powered by 2.5V, 3V, 3.3V, or 5V rails. The fixed 2.32V threshold makes it suitable for specific low-voltage monitoring needs. Consider the SC-70-3 footprint for space-constrained designs. Verify that the active-high output polarity aligns with the receiving logic interface requirements of the target microprocessor or digital system.
This device belongs to the MAX6327X series of ultra-low-power reset circuits. It shares architectural similarities with the MAX6326 and MAX6328 but differs in output polarity and drive type. The series is designed to eliminate external components in microprocessor systems. It provides reliable supervision for digital circuits without requiring manual reset inputs or watchdog timers.
Public confirmed substitute part numbers: MAX6327XR23+TCT, MAX6327XR23+TDKR.
