MAX6326XR23+

Supervisors Overview

The MAX6326XR23+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single power supply with a fixed reset threshold of 2.30V. The device features a push-pull active-low output and provides a minimum reset timeout of 100ms to ensure stable system initialization. Designed for surface-mount applications, it utilizes an SC-70-3 package. The component operates within a temperature range of -40°C to +85°C and supports supply voltages up to its threshold limit.

Supervisors Feature Summary

• Provides reliable system reset generation upon detection of undervoltage conditions
• Features a dedicated manual reset input for external control capability
• Delivers a defined reset pulse duration to prevent premature processor activation

Supervisors Applications

• Embedded controller systems requiring precise voltage supervision
• Portable battery-powered devices needing low-power monitoring
• Industrial equipment operating in extended temperature environments

Supervisors Procurement Notes

Verify the specific suffix 'R23' corresponds to the 2.30V threshold variant when sourcing. Confirm that the '+T' designation indicates tape-and-reel packaging if automated assembly is required. Ensure compatibility with SC-70-3 footprints during PCB layout validation. Cross-reference manufacturer documentation for any recent product change notices affecting pinout or electrical characteristics.

Supervisors Selection Notes

Select this component when a fixed 2.30V threshold is required for single-supply monitoring. Consider the SC-70-3 package size constraints against available board space. Evaluate the 100ms minimum timeout requirement against system startup timing needs. Verify that the active-low push-pull output interface matches the target microprocessor reset pin logic requirements.

Supervisors Part Context

This part belongs to the MAX6326 family of ultra-low-power reset circuits. The family offers various fixed thresholds and adjustable options across different package types. The XR23 variant specifically targets applications requiring a 2.30V trip point. It complements other Maxim Integrated supervisors designed for portable and industrial electronics.

Supervisors Replacement Considerations

Direct substitutes include other MAX6326 variants with identical SC-70-3 packaging but different voltage thresholds, such as the MAX6326XR24+T for 2.40V applications. Ensure functional equivalence regarding reset timeout and output drive capability when considering cross-family alternatives.
