AP9211S-DD-HAC-7

Battery Management Overview

The AP9211S-DD-HAC-7 is a single-chip protection solution designed for one-cell lithium-ion or lithium-polymer rechargeable battery packs. It integrates comprehensive fault protection mechanisms, including overcharge current/voltage, overdischarge current/voltage, and short-circuit safeguards. The device operates within an ambient temperature range of -40°C to 85°C and utilizes a surface-mount 6-UDFN package with an exposed pad.

Battery Management Feature Summary

• Integrates complete protection logic for single-cell Li-ion and Li-polymer batteries
• Provides active monitoring for overcharge, overdischarge, and short-circuit conditions
• Designed for compact surface-mount applications with thermal exposure capabilities

Battery Management Applications

• Protection circuits for portable electronic devices
• Safety management in consumer electronics battery packs
• Power management systems for mobile communication hardware

Battery Management Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors. Confirm the specific suffix DD-HAC-7 matches design requirements. Check for obsolescence notifications as this series may be scheduled for discontinuation. Ensure ESD handling protocols are followed during assembly due to the sensitive nature of integrated circuit protection components.

Battery Management Selection Notes

Select this component when a unified solution for single-cell battery protection is required. It eliminates the need for discrete protection components by integrating all necessary sensing and switching functions. Consider the UDFN package size for space-constrained designs. Verify that the operating voltage and current limits align with the target battery cell specifications before integration into the final product architecture.
