MAX6441KAKQVD3-T

Overview

The MAX6441KAKQVD3-T is a low-power, single-level battery monitor with hysteresis and an integrated microprocessor reset supervisor. It operates from a supply voltage of 1 V to 5.5 V in an SOT-23-8 package. The device provides factory-trimmed thresholds for detecting low-battery conditions and includes an active-low reset output for the microprocessor. It supports manual reset via a push-button and requires no external components.

Feature Summary

• Integrates a single low-battery monitor with hysteresis to prevent output chattering during voltage transitions.
• Includes an independent microprocessor supervisor that monitors VCC and provides an active-low reset signal.
• Supports manual system reset through a dedicated push-button input without requiring external components.

Applications

• Single-cell lithium-ion battery monitoring
• Multicell alkaline or NiCd/NiMH battery systems
• Microprocessor power management circuits

Procurement Notes

Verify the exact suffix configuration against the manufacturer datasheet to ensure correct threshold voltages and package type. Confirm RoHS compliance status and lead times directly with authorized distributors as availability varies. Ensure the specific variant matches the required operating temperature range and electrical specifications for the target application.

Selection Notes

Select this component when a compact solution is needed for monitoring single-cell batteries with integrated reset functionality. The fixed factory-trimmed thresholds simplify design by eliminating the need for external resistor dividers. Consider the SOT-23-8 package size constraints and the requirement for an active-low reset signal compatible with the target microprocessor.

Part Context

This part belongs to the MAX6439–MAX6442 family of ultra-low-power battery monitors. These devices are designed for portable applications where minimizing quiescent current is critical. The family offers various threshold combinations and output configurations to suit different battery chemistries and system requirements.

Replacement Considerations

Check for other variants within the MAX6441 series that may offer different threshold voltages or dual-output options. Verify pin compatibility if substituting with similar battery monitors from Analog Devices or Maxim Integrated.
