MAX6466XR34+T

Overview

The MAX6466XR34+T is a single-channel ultra-low-power voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 6 V and features an active low, open-drain output. The device monitors input voltages with a threshold of 3.4 V and provides a reset delay time of 260 ms. It is housed in a compact SC-70-3 surface-mount package and maintains accuracy within 2.5%. The component supports an operating temperature range from -40°C to +125°C and draws a typical quiescent current of 3.5 µA.

Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Integrated precision bandgap reference and comparator
• Internal 5% threshold hysteresis for noise immunity
• Microprocessor supervisory function with defined timeout period

Applications

• Battery-powered portable electronics monitoring
• Embedded system voltage supervision
• Consumer device power management
• Industrial control system voltage detection

Procurement Notes

Verify the specific suffix 'XR34' against official manufacturer documentation to confirm the exact threshold voltage and package variant. Confirm RoHS compliance status through the latest datasheet revision. Check for obsolescence notices or lifecycle changes directly from Analog Devices. Ensure the open-drain output configuration matches the target circuit design requirements before procurement.

Selection Notes

Select this component when a microprocessor supervisory circuit with a fixed 260 ms timeout is required. The open-drain output necessitates an external pull-up resistor. Verify that the 3.4 V threshold aligns with the monitored rail voltage. Consider the SC-70-3 package size constraints during PCB layout. Ensure the 3.5 µA quiescent current meets the system's power budget requirements.

Part Context

This part belongs to the MAX6461–MAX6466 family of ultra-low-power voltage detectors and microprocessor supervisory circuits. The MAX646x series distinguishes itself by offering various threshold options and output configurations. The MAX6466 specifically provides supervisory functions with longer reset timeouts compared to the faster MAX6461–MAX6463 voltage detectors.
