MAX6849KAVD7-T

Overview

The MAX6849KAVD7-T is a low-power, adjustable battery monitor featuring dual outputs and an integrated microprocessor supervisor. Designed for single-cell applications, it supports multiple chemistries including lithium-ion, nickel-based, and lead-acid batteries. The device provides precise voltage monitoring with hysteresis to prevent false triggering. It includes a push-pull reset output compatible with various logic families. The component operates within a wide supply voltage range and offers configurable thresholds for under-voltage and over-voltage detection.

Feature Summary

• Dual-output architecture for independent monitoring of distinct voltage thresholds
• Integrated microprocessor supervisor with push-pull reset capability
• Adjustable threshold settings supporting multiple battery chemistries
• Built-in hysteresis to ensure stable operation during voltage transitions

Applications

• Portable electronic devices requiring reliable battery level monitoring
• Laptop and notebook computer power management systems
• Handheld instruments utilizing rechargeable battery packs
• Medical equipment dependent on stable power supply supervision

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm the manufacturer designation as Analog Devices Inc. or Maxim Integrated to ensure authenticity. Check for RoHS compliance markings if environmental regulations apply to your assembly process. Ensure the SOT23-8 package type matches your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when dual independent voltage monitoring is required alongside system reset functionality. It is suitable for designs needing adjustable thresholds rather than fixed reference voltages. Consider its low quiescent current for battery-operated applications where power efficiency is critical. Verify that the operating temperature range meets your specific environmental constraints.

Part Context

This part belongs to the MAX684x family of battery monitors from Maxim Integrated. These devices are engineered for portable electronics requiring robust power management. The series typically integrates monitoring and reset functions into a compact package. This specific model focuses on dual-channel capability for enhanced system reliability.

Replacement Considerations

Check for MAX6846 variants if single-channel monitoring suffices for your design. Verify pin compatibility with MAX6849+T versions if lead-free specifications differ in your region. Consult official substitution guides for updated equivalents from Analog Devices.
