AT1002-X

Battery Management Overview

The AT1002-X is a high-precision protection integrated circuit designed for single-cell lithium-ion and lithium-polymer rechargeable batteries. It provides comprehensive fault protection including overcharge, overdischarge, and short-circuit conditions. The device features an open-drain status output to indicate the battery's health state. It operates within a specified voltage range with low quiescent current consumption to minimize standby power loss in portable applications.

Battery Management Feature Summary

• Integrated protection against overcharge, overdischarge, and short-circuit events for single-cell Li-ion/Li-Po batteries
• Open-drain status output pin indicating battery operational state
• Low quiescent current design to preserve battery life during storage or standby modes

Battery Management Applications

• Single-cell lithium-ion battery packs in portable electronics
• Lithium-polymer battery protection in consumer devices
• Power management systems requiring compact battery safety solutions

Battery Management Procurement Notes

Verify the specific suffix variant (e.g., -X) matches the required overvoltage trip point, as the AT1002 series offers multiple voltage options. Confirm package type and RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the selected part supports the specific cell chemistry and capacity of the target application.

Battery Management Selection Notes

Select the AT1002-X when a dedicated, low-component-count solution for single-cell battery protection is required. Compare its fixed trip points against other variants in the AT1002 series to ensure compatibility with the specific battery cell voltage characteristics. Consider the package size constraints and thermal requirements of the final assembly.

Battery Management Part Context

The AT1002-X belongs to the AT1002 series from Analog Technologies, Inc., which focuses on battery management ICs. This series includes various models tailored for different cell counts and protection levels. The AT1002-X specifically targets single-cell applications, distinguishing it from multi-cell protection controllers in the broader portfolio.

Battery Management Replacement Considerations

Direct substitutes may include other AT1002 series variants with adjusted voltage thresholds. Cross-referencing with similar single-cell protection ICs from manufacturers like Texas Instruments or ON Semiconductor requires verifying matching trip voltages and package dimensions.
