MAX6465XR23+T

Supervisors Overview

The MAX6465XR23+T is a single-channel ultra-low-power voltage monitor from the MAX6465 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.6V to 6V and features an active-high push-pull output. The device provides a precise threshold voltage of 2.3V with 2.5% accuracy and includes internal hysteresis. It consumes only 3.5µA of quiescent current and offers a reset timeout delay of 260ms. The component is housed in a compact SC-70-3 surface-mount package and supports operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Internal precision bandgap reference and comparator for reliable monitoring
• Fixed trip thresholds with built-in 5% hysteresis to prevent false triggering
• Active-high push-pull output configuration for direct microprocessor interfacing

Supervisors Applications

• Monitoring battery voltages in portable electronic devices
• Supervising power-supply rails in embedded systems
• Providing reset signals for microprocessors and digital logic circuits

Supervisors Procurement Notes

Verify the specific suffix 'XR23' to confirm the 2.3V threshold and SC-70-3 package variant. Confirm RoHS compliance status through official manufacturer documentation. Check for obsolescence notices or lifecycle changes as availability may be restricted. Ensure the active-high output polarity matches the target system design requirements before procurement.

Supervisors Selection Notes

Select this component when a fixed 2.3V supervision level is required with low standby current. The active-high output distinguishes it from active-low variants in the same series. Verify that the 260ms reset delay meets the system startup timing constraints. Consider the SC-70-3 footprint for space-constrained PCB layouts compared to larger packages.

Supervisors Part Context

This part belongs to the MAX6461–MAX6466 family of voltage detectors and µP supervisory circuits. These devices eliminate external components by integrating trimmed resistor networks and comparators. The family covers various threshold voltages and output polarities to support nominal system voltages from 1.6V to 5.5V, ensuring circuit reliability without adjustments.

Supervisors Replacement Considerations

Cross-reference with other MAX6465 series parts for different threshold voltages or output polarities. Verify pinout compatibility if substituting with similar SC-70-3 supervisors from other manufacturers.
