MAX6328XR29+T

Overview

The MAX6328XR29+T is a single-channel voltage supervisor IC manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.6V to 5.5V and features a fixed reset threshold of 2.93V. The device provides an active-low open-drain or open-collector reset output with a minimum timeout period of 100ms. Designed for surface-mount installation, it is housed in a compact SOT-23-3 package. The component supports a wide operating temperature range from -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Provides simple reset and power-on-reset functionality for monitoring a single voltage rail
• Features an active-low open-drain or open-collector output compatible with various logic families
• Ensures reliable system recovery through a guaranteed minimum reset timeout duration

Applications

• Embedded systems requiring precise power management supervision
• Microcontroller-based designs needing stable power-on reset sequences
• Portable electronic devices utilizing low-voltage battery supplies

Procurement Notes

Verify the specific suffix 'R29' corresponds to the required 2.93V threshold during procurement. Confirm that the SOT-23-3 package dimensions align with the target PCB footprint. Ensure the selected supplier provides components with valid traceability documentation. Check for any recent product change notices regarding manufacturing site transfers. Validate compliance requirements against the latest RoHS3 specifications before finalizing orders.

Selection Notes

Select this component when a fixed 2.93V threshold is appropriate for the monitored circuit. Consider the open-drain output configuration for compatibility with external pull-up resistors. Evaluate the 100ms minimum timeout against the system's startup timing requirements. Assess the SOT-23-3 package size constraints relative to available board space. Verify that the operating temperature range meets the environmental conditions of the intended application.
