MAX6441KAEISD3-T

Overview

The MAX6441KAEISD3-T is a low-power, single/dual-level battery monitor with hysteresis and an integrated microprocessor reset supervisor. It operates within a supply voltage range of 1 V to 5.5 V and features an active-low reset output triggered at a threshold of 2.925 V. The device provides dual low-battery outputs with factory-trimmed thresholds set at 3.5 V (high) and 3.0 V (low). Packaged in an SOT-23-8 surface-mount case, it supports operation from -40°C to +85°C.

Feature Summary

• Integrates microprocessor supervision with manual reset capability via push-button
• Provides dual low-battery outputs for system status signaling across three states
• Includes hysteresis on battery thresholds to prevent output chattering
• Requires no external components for basic operation

Applications

• Single-cell lithium-ion battery monitoring systems
• Multicell alkaline or NiCd/NiMH battery management
• Microprocessor reset timing in portable electronics
• Low-power system operation alerts

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status as datasheets may list leaded variants alongside lead-free versions. Ensure the manufacturer source is Analog Devices or Maxim Integrated to guarantee authenticity. Check for any obsolescence notices or limited availability warnings associated with this specific part number revision.

Selection Notes

Select this component when dual-stage battery warning signals are required alongside processor reset functionality. The fixed 2.925 V reset threshold and specific 3.5 V/3.0 V battery thresholds suit applications needing precise voltage monitoring without external trimming. Consider the SOT-23-8 package for space-constrained designs requiring surface-mount integration.

Part Context

This device belongs to the MAX6439–MAX6442 family of ultra-low-power battery monitors. While the MAX6441 offers dual low-battery outputs, other family members provide single-output options. All variants share the integrated µP supervisor and manual reset features, differing primarily in their factory-trimmed voltage thresholds and package configurations.

Replacement Considerations

Cross-reference with MAX6441KACJTD3-T or MAX6441KADGZD3+T for similar dual-output functionality. Verify that alternative parts match the 2.925 V reset threshold and 3.5 V/3.0 V battery limits. Ensure package compatibility and operating temperature ranges align with design requirements before substitution.
