MAX6466XR22+T

Overview

The MAX6466XR22+T is a single-channel ultra-low-power voltage monitor manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.2 V to 6 V and features an active low, open-drain output. The device provides a reset threshold of 2.2 V with a typical accuracy of 2.5%. It includes a fixed reset delay time of 150 ms and consumes only 3.5 µA of quiescent current. The component is housed in a compact SC-70-3 surface-mount package and supports an industrial temperature range from -40°C to +125°C.

Feature Summary

• Ultra-low power consumption for extended battery life
• Compact SC-70-3 surface-mount packaging
• Active low open-drain reset output configuration

Applications

• Portable electronic devices requiring power supervision
• Battery-operated systems with limited power budgets
• Embedded microcontroller reset circuits

Procurement Notes

Verify the specific suffix 'XR' confirms the SC-70-3 package and '+T' indicates tape-and-reel delivery. Confirm RoHS compliance status through official documentation. Check current availability as distribution may be restricted or limited. Ensure the selected threshold voltage matches the target system rail requirements precisely.

Selection Notes

Select this component when a single voltage channel with low quiescent current is required. The 150 ms reset delay suits applications tolerant of short startup times. Verify that the open-drain output interface is compatible with the downstream logic levels. Consider the SC-70-3 footprint constraints during PCB layout design.
