Frequently Asked Questions
How many monitoring functions does the MAX6441KACISD3+T provide, and what do they do?
The MAX6441KACISD3+T integrates 2 monitoring functions: a low-battery voltage detector and a manual reset input. The voltage supervisor continuously checks the cell voltage against a fixed internal reference, asserting a logic-level output when the battery drops below the preset threshold. This dual functionality eliminates the need for a separate reset IC in many single-cell designs.
What package does the MAX6441KACISD3+T use, and how does it affect PCB layout space?
The device comes in an 8-pin SOT23 package (TSSOP8, 0.1-inch pitch equivalent), which occupies roughly 3 mm x 3 mm of board area. This compact footprint allows placement next to a coin cell or AA battery connector without consuming significant PCB real estate, making it a strong choice for wearable and handheld product designs requiring less than 10 mm² component area.
Which battery chemistries and cell configurations is the MAX6441KACISD3+T designed to monitor?
The MAX6441KACISD3+T is optimized for single-cell lithium-ion, lithium-polymer, and alkaline battery monitoring applications where the nominal cell voltage ranges from approximately 1.5 V to 4.2 V. It is not intended for multi-cell series stacks without external scaling resistors. The fixed internal threshold reference makes it particularly efficient in single-cell designs requiring minimal external component count.
Is the MAX6441KACISD3+T supplied in tape-and-reel format, and what does that mean for procurement?
Yes, the '+T' suffix in the MAX6441KACISD3+T part number confirms tape-and-reel packaging, which is standard for automated pick-and-place SMT assembly. Tape-and-reel reels typically hold 3,000 units per reel, enabling efficient high-volume procurement and reducing per-unit handling cost. This format is directly compatible with standard IPC-7711 feeder systems used in contract manufacturing.
