MAX6328UR26+T

Overview

The MAX6328UR26+T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and features a fixed threshold voltage of 2.63 V for monitoring a single input channel. The device provides an active low, open-drain reset output with a typical reset delay time of 185 ms. It exhibits high accuracy of 1.5% and consumes a maximum operating supply current of 500 nA. The component is designed for surface mount installation in a SC-70-3 package and functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Ultra-low-power consumption suitable for battery-operated systems
• Fixed threshold voltage ensures precise power monitoring without external components
• Compact SC-70-3 surface-mount packaging for space-constrained designs

Applications

• Portable electronic devices requiring efficient power management
• Battery-powered instrumentation and sensors
• Embedded systems needing reliable voltage supervision

Procurement Notes

Verify the specific suffix UR26 to confirm the 2.63 V threshold and SC-70-3 package configuration. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm RoHS compliance status if required by regulatory standards. Check manufacturer documentation for any recent product change notices or lifecycle updates that may affect long-term availability.

Selection Notes

Select this component when a fixed 2.63 V threshold is required for single-channel voltage monitoring. Consider the ultra-low quiescent current for applications where power efficiency is critical. Verify that the open-drain output interface matches the logic levels of the connected microcontroller or system controller. Ensure the operating temperature range meets the environmental conditions of the intended application.

Part Context

This part belongs to the MAX6328X series of ultra-low-power reset circuits. The series offers various threshold voltages and package options to suit different design needs. The MAX6328 family is designed to provide reliable supervision for digital systems, ensuring proper initialization and operation under varying power conditions.

Replacement Considerations

Cross-reference tools may identify parts like the NCP803SN263T1G as parametrically similar due to matching threshold voltage and package type. Verify functional equivalence regarding reset delay times and output configurations before substitution.
