MAX6328XR30+T

Overview

The MAX6328XR30+T is a single-channel 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 3 V with an accuracy of 1.5%. The device provides an active-low, open-drain reset output with a minimum reset timeout of 100 ms. Designed for surface-mount installation in SOT-23-3 packages, it consumes a typical operating current of 500 nA. The component supports a wide operating temperature range from -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Fixed 3V threshold ensures precise monitoring of system voltages
• Open-drain output allows flexible interfacing with various logic families

Applications

• Portable electronic devices requiring extended battery life
• Microprocessor and microcontroller system supervision
• Battery-powered instrumentation and measurement equipment

Procurement Notes

Verify the specific suffix 'R30' corresponds to the required 3V threshold and 100ms timeout during procurement. Confirm package availability in SOT-23-3 format matches design constraints. Ensure compliance with RoHS3 directives if applicable to your region. Cross-reference manufacturer datasheets for any recent pinout or electrical specification updates before finalizing orders.

Selection Notes

Select this component when a low-power, single-supervisor solution is needed for 3V rails. Consider the open-drain output requirement for pull-up resistor integration. Evaluate thermal performance within the specified -40°C to +85°C range. Compare against alternatives if manual reset or watchdog functionality is required, as this model lacks those features.

Part Context

Part of the MAX6328U series of ultra-low-power reset circuits. Designed for applications where power conservation is critical. Shares family characteristics with other MAX6328 variants differing primarily in threshold voltages and timeout periods. Manufactured using advanced CMOS technology for high reliability and low standby current.

Replacement Considerations

Check MAX6328XR30+ without the trailing T for tape-and-reel variations. Verify MAX6328UR30+T for identical electrical specifications in alternative packaging. Consult official substitution guides for pin-compatible upgrades with enhanced features like manual reset inputs.
