AP9211SA-AJ-HAC-7

Battery Management Overview

The AP9211SA-AJ-HAC-7 is a single-chip protection IC designed for one-cell lithium-ion or lithium-polymer rechargeable battery packs. It integrates high-side and low-side N-channel MOSFET drivers with comprehensive protection features including overcharge, overdischarge, overcurrent, and short-circuit safeguards. The device operates within a supply voltage range of 1.5 V to 5.5 V and utilizes a U-DFN2030-6 surface-mount package. It supports automatic wake-up functionality and includes a dedicated charge control pin for managing charging cycles.

Battery Management Feature Summary

• Integrates dual N-channel MOSFET drivers for high-side and low-side switching applications
• Provides multi-stage protection against overvoltage, undervoltage, and excessive current conditions
• Supports automatic system wake-up from deep discharge states

Battery Management Applications

• Single-cell lithium-ion battery pack protection
• Lithium-polymer rechargeable battery management systems
• Portable electronic devices requiring integrated cell protection

Battery Management Procurement Notes

Verify the specific suffix AJ-HAC-7 against the manufacturer's official datasheet to confirm pinout compatibility and functional specifications. Confirm availability status as product lifecycles may change. Ensure the ordering part number matches the exact package and tape/reel configuration required for your assembly process. Cross-reference with Diodes Incorporated documentation for any recent design changes or obsolescence notices.

Battery Management Selection Notes

Select this component when a compact, single-chip solution is required for protecting single-cell Li-ion or Li-Po batteries. It is suitable for designs needing integrated power switches without external MOSFETs. Consider the U-DFN2030-6 package size constraints and operating temperature range. Verify that the automatic wake-up feature aligns with the system's power management requirements.

Battery Management Part Context

This part belongs to the AP9211 series of battery protection ICs from Diodes Incorporated. The series focuses on providing complete protection solutions for portable electronics by combining monitoring logic with power switching capabilities in a minimal footprint. It serves as an alternative to discrete protection circuits, simplifying PCB layout and reducing component count.

Battery Management Replacement Considerations
