MAX6328UR25+T

Supervisors Overview

The MAX6328UR25+T is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features a fixed threshold voltage of 2.5 V for monitoring a single input channel. The device provides an active low, open-drain output with a reset delay time of 185 ms. It functions reliably across an operating temperature range from -40°C to +85°C. Key electrical characteristics include a power supply accuracy of 1.5% and a typical operating current of 500 nA. The component is housed in a SOT-23-3 surface-mount package.

Supervisors Feature Summary

• Ultra-low-power consumption suitable for battery-operated applications

Supervisors Procurement Notes

Verify the complete part number including suffixes such as UR25+T against official manufacturer documentation to ensure correct threshold voltage and packaging specifications. Confirm RoHS compliance status through certified datasheets or manufacturer certificates prior to procurement. Cross-reference with authorized distributors to validate authenticity and traceability. Ensure the selected variant matches the required operating temperature range and output type for the specific design implementation.

Supervisors Selection Notes

Select this component when a fixed 2.5 V threshold is required for single-channel voltage monitoring. Consider the open-drain output capability if level shifting or wired-OR configurations are necessary. Evaluate the 500 nA quiescent current against system power budgets. Verify that the SOT-23-3 package dimensions fit the available PCB space. Compare reset delay times with other variants in the MAX6328 family if timing constraints differ.

Supervisors Part Context

This component belongs to the MAX6328U series of ultra-low-power reset circuits. The series offers various fixed threshold voltages to accommodate different supply rails. These devices are designed to provide reliable power management in compact form factors. The MAX6328 family is widely used in consumer electronics and industrial systems where power efficiency and small footprint are critical design parameters.

Supervisors Replacement Considerations

Check for MAX6328 variants with different threshold suffixes (e.g., UR22, UR30) if voltage levels differ. Verify pinout compatibility with alternative supervisors in the same package family.
