MAX6327XR29-T

Overview

The MAX6327XR29-T is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for voltage monitoring applications. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed threshold voltage of 2.93 V. The device utilizes an SC-70-3 package with surface-mount installation. It provides an active high, push-pull output signal without manual reset or watchdog timer capabilities. The component supports a reset delay time of 280 ms and maintains low power consumption with a working supply current of 500 nA. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides precise voltage supervision with a fixed 2.93 V threshold
• Features ultra-low power consumption suitable for battery-operated systems
• Delivers active high push-pull output for direct logic interfacing
• Utilizes compact SC-70-3 packaging for space-constrained designs

Applications

• Portable electronic devices requiring efficient power management
• Microcontroller system reset circuits
• Battery-powered instrumentation
• Embedded systems voltage monitoring

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm that the part number corresponds to the 2.93 V threshold variant within the MAX6327X series. Ensure compatibility with SC-70-3 footprint requirements in the target design. Check availability status as distribution may be limited or subject to factory orders. Validate RoHS compliance documentation if required for regulatory standards.

Selection Notes

Select this component when a fixed 2.93 V reset threshold is required for single-input voltage monitoring. Choose the active high push-pull output type for direct connection to digital logic inputs without external pull-up resistors. Consider the 500 nA quiescent current for applications prioritizing minimal standby power drain. Opt for the SC-70-3 package when board space is limited compared to larger SOT-23 alternatives.

Part Context

This part belongs to the MAX6327X series of uPower Reset Circuits from Maxim Integrated. The series offers various threshold voltages including 2.5 V, 3 V, 3.3 V, and 5 V options. The MAX6327XR29-T specifically denotes the 2.93 V threshold variant with reel packaging. It shares common family features such as low power operation and compact packaging but differs in specific electrical parameters like threshold voltage and output polarity compared to other series members.

Replacement Considerations

MAX6327XR29+T serves as a lead-free equivalent variant within the same series.
