MAX6466XR26+T

Overview

The MAX6466XR26+T is a single-channel ultra-low-power voltage detector manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.2 V to 6 V and features an active low, open-drain output. The device monitors input voltage against a fixed threshold of 2.6 V with a reset delay time of 150 ms. It exhibits a quiescent current of 3.5 µA and maintains a threshold accuracy of 2.5%. The component is housed in a compact SC-70-3 surface-mount package and supports an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Ultra-low power consumption with 3.5 µA operating current for battery-sensitive applications
• Fixed internal threshold voltage eliminates external resistor networks
• Active low open-drain output simplifies interface with microprocessors
• Compact SC-70-3 package suitable for space-constrained designs

Applications

• Portable electronic devices requiring efficient power monitoring
• Battery-operated systems needing low standby current
• Microprocessor supervisory circuits in embedded systems

Procurement Notes

Verify the specific suffix 'XR' confirms the SC-70-3 package and tape-and-reel delivery format. Confirm RoHS compliance status through official documentation. Check current lifecycle status as availability may vary. Ensure the 2.6 V threshold matches system requirements before procurement.

Selection Notes

Select this component when a fixed 2.6 V threshold is required for single-supply monitoring. The SC-70-3 package offers a small footprint compared to SOT-23 alternatives. Consider the 150 ms reset delay for timing constraints. Verify that the open-drain output configuration aligns with the pull-up requirements of the connected logic circuitry.

Part Context

This part belongs to the MAX6466 family of voltage supervisors. The series provides various fixed threshold options ranging from 1.6 V to 5.5 V. All members share similar electrical characteristics including low quiescent current and high accuracy. The family is designed for reliable operation in harsh industrial environments.

Replacement Considerations

Other MAX6466 variants with different thresholds (e.g., XR22, XR35) serve as functional substitutes if voltage levels differ. Cross-reference pinouts to ensure compatibility with existing PCB layouts.
