MAX6327XR23+

Overview

The MAX6327XR23+ is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single input voltage with a threshold of 2.3 V. The device features an active high, push-pull output and includes a reset delay time of 280 ms. It operates within a supply voltage range up to 5.5 V and consumes 500 nA of working power current. The component supports surface mount installation in an SC-70-3 package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Provides precise voltage supervision for single-channel monitoring applications
• Delivers active high push-pull output signals for direct logic interfacing
• Ensures system stability through a fixed 280 ms reset delay timer
• Maintains ultra-low power consumption suitable for battery-operated devices

Applications

• Microcontroller unit (MCU) power-on reset circuits
• Battery-powered embedded systems requiring low quiescent current
• Portable electronic devices needing compact surface-mount supervision
• Industrial control systems operating in extended temperature ranges

Procurement Notes

Verify the specific suffix 'R23' to confirm the 2.3 V threshold voltage, as the MAX6327X series offers multiple threshold options. Confirm the SC-70-3 package compatibility with your PCB footprint. Check current availability status, as supply constraints may affect lead times. Ensure RoHS compliance documentation is obtained for regulatory requirements. Validate that the active high output polarity matches your system design logic.

Selection Notes

Select this component when a fixed 2.3 V threshold is required for voltage monitoring. Choose the SC-70-3 package for space-constrained designs. Opt for the active high push-pull output if direct interface with digital logic is needed without external pull-up resistors. Consider the 500 nA current consumption for energy-sensitive applications. Verify that the 280 ms delay meets the startup timing requirements of the monitored system.

Part Context

The MAX6327XR23+ belongs to the MAX6327X family of uPower Reset Circuits from Maxim Integrated. This series is designed for low-power applications requiring reliable voltage supervision. The device integrates essential monitoring functions into a minimal footprint, making it suitable for portable and industrial electronics where size and power efficiency are critical design parameters.

Replacement Considerations

Cross-reference other MAX6327X variants with different threshold voltages if the 2.3 V level is not suitable. Verify pinout compatibility with alternative supervisor ICs in the SC-70-3 package. Ensure that replacement parts maintain similar reset delay characteristics and output drive capabilities.
