MAX6847KASD3-T

Overview

The MAX6847KASD3+T is a low-power, adjustable battery monitor with hysteresis and an integrated microprocessor reset circuit. It operates within a supply voltage range of 1.6 V to 5.5 V. The device is housed in an SOT-23-8 package and supports industrial operating temperatures from -40°C to +85°C. Designed for battery management applications, it combines voltage monitoring and system reset functions into a single compact component.

Feature Summary

• Integrates adjustable battery monitoring with built-in hysteresis to prevent output chatter during threshold crossings.
• Includes an on-chip microprocessor reset generator to ensure reliable system initialization and recovery.
• Operates efficiently at ultra-low supply voltages starting from 1.6 V, suitable for portable power-constrained designs.

Applications

• Battery-powered portable electronic devices requiring precise voltage supervision
• Microprocessor and digital systems needing combined power-on reset and brown-out detection
• Low-voltage battery management circuits in consumer electronics

Procurement Notes

Verify the exact suffix configuration against the manufacturer's current datasheet, as ordering codes may vary. Confirm availability status directly with authorized distributors, as this specific part number may be subject to limited stock or discontinuation notices. Ensure the package type matches your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a single IC solution is required for both battery level monitoring and system reset generation. The adjustable threshold feature allows customization for specific battery chemistries. Verify that the SOT-23-8 package dimensions fit the design constraints and that the 1.6 V minimum operating voltage aligns with the target power supply rails.

Part Context

This part belongs to the MAX6847 family of low-power supervisory circuits from Analog Devices/Maxim Integrated. The family focuses on providing essential power management functions in minimal space. The KASD3 suffix typically denotes specific threshold adjustments and packaging details within this product line.

Replacement Considerations

Consult the official MAX6847 datasheet for pin-compatible alternatives within the same family. Cross-reference with other Maxim Integrated voltage supervisors if specific threshold values differ. No direct public substitute part numbers are confirmed in the provided documentation.
