MAX6326XR28+T

Supervisors Overview

The MAX6326XR28+T is a supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within an ambient temperature range of -40°C to +85°C and utilizes a SC-70-3 package. The device features a fixed overvoltage threshold of 2.842 V and supports push-pull or totem pole output configurations for a single channel. Power dissipation is rated at 174 mW, and it does not include power fail detection capabilities.

Supervisors Feature Summary

• Provides hardware reset signal generation based on monitored supply voltage levels
• Utilizes ultra-low-power architecture suitable for battery-operated systems
• Offers compact surface-mount packaging for space-constrained designs

Supervisors Applications

• Microprocessor reset circuits in embedded systems
• Battery-powered portable devices requiring low quiescent current
• Industrial instrumentation control logic supervision

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm lot traceability and RoHS compliance status (+ suffix indicates lead-free). Ensure storage conditions adhere to moisture sensitivity level requirements prior to reflow soldering. Validate part marking against official datasheet specifications to prevent counterfeit substitution.

Supervisors Selection Notes

Select this component when a fixed 2.842 V threshold is required for system supervision. Consider the SC-70-3 package constraints for PCB layout. Evaluate if push-pull output drive strength meets load requirements. Verify that the absence of power-fail detection aligns with system safety needs.

Supervisors Part Context

This part belongs to the MAX6326 family of microprocessor supervisors. These circuits are designed to monitor voltage rails and assert reset signals upon fault detection. The XR28 variant specifically denotes the 2.842 V threshold option within the series, differentiated by other suffixes indicating different voltage thresholds.

Supervisors Replacement Considerations

Cross-reference with MAX6326XR28-T for identical functionality without lead-free certification. Check MAX6326UR38+T for SOT-23 package compatibility with similar electrical characteristics. Verify pinout and threshold voltage matches before substituting.
