MAX6440UTFJTD7-T

Overview

The MAX6440UTFJTD7-T is a single battery monitor IC from the MAX6439–MAX6442 family, designed for ultra-low-power applications. It operates within a supply voltage range of 1 V to 5.5 V and features an integrated microprocessor supervisor with an active-low reset output. The device provides dual low-battery outputs to signal battery status levels. It utilizes a SOT-23-6 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates microprocessor supervisor with manual reset capability
• Provides dual low-battery output options for system status signaling
• Factory-trimmed thresholds optimized for specific battery chemistries

Applications

• Single-cell lithium-ion battery monitoring
• Multicell alkaline or NiCd/NiMH battery systems
• Low-power embedded system power management

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as specific variants may differ. Ensure the ordering suffix matches the required threshold specifications. Check current availability as supply constraints may affect lead times. Validate package integrity upon receipt.

Selection Notes

Select this variant based on its specific factory-trimmed high and low battery thresholds. Verify compatibility with the target microprocessor reset timing requirements. Ensure the SOT-23-6 package fits the design footprint. Confirm that the operating voltage range aligns with the system's power supply rails.

Part Context

This component belongs to the MAX6439–MAX6442 family of battery monitors. These devices are engineered to replace external discrete components by integrating monitoring and supervision functions into a single chip. The family offers various threshold combinations to suit different battery types without requiring external resistors.

Replacement Considerations

Substitute parts must match the SOT-23-6 package and functional pinout. Verify equivalent threshold voltages and reset timing characteristics. Ensure the replacement supports the same operating temperature range and supply voltage limits.
