MAX6442KAKQSD3

Overview

The MAX6442KAKQSD3 is a low-power, single/dual-level battery monitor with an integrated microprocessor reset supervisor. It operates within a supply voltage range of 1 V to 5.5 V and is housed in an SOT-23-8 surface-mount package. The device supports an operating temperature range from -40°C to +85°C. It provides factory-trimmed thresholds for detecting low-battery conditions and includes manual reset functionality without requiring external components.

Feature Summary

• Integrates ultra-low-power battery monitoring with independent microprocessor supervision
• Offers factory-trimmed threshold combinations for various battery chemistries
• Provides active-low reset output with manual push-button reset capability

Applications

• Single-cell lithium-ion battery systems
• Multicell alkaline or NiCd/NiMH battery applications
• Portable electronics requiring real-time battery monitoring

Procurement Notes

Verify component authenticity through authorized distributors due to potential availability constraints. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure the ordering suffix matches the required threshold configuration and packaging format. Check current lifecycle status as some variants may be discontinued or limited supply.

Selection Notes

Select this variant based on the specific factory-trimmed low-battery threshold combination required for the target battery chemistry. Verify that the SOT-23-8 package fits the PCB layout constraints. Ensure the operating voltage range aligns with the system's power supply specifications. Consider the thermal performance within the specified -40°C to +85°C range for the intended environment.

Part Context

Part of the MAX6439–MAX6442 family of battery monitors. Designed for portable devices needing reliable power management. Integrates monitoring and reset functions to reduce component count. Manufactured by Analog Devices Inc./Maxim Integrated.

Replacement Considerations

Check MAX6442 variants with different suffixes for identical electrical characteristics but different thresholds or packages. Verify compatibility with existing firmware if reset timing parameters differ slightly between sub-models.
