AP9221SA-AS-HAC-7

Battery Management Overview

The AP9221SA-AS-HAC-7 is a single-chip battery protection solution designed for one-cell lithium-ion or lithium-polymer battery packs. It integrates high-side and low-side N-channel MOSFETs with dedicated control circuitry to provide comprehensive protection against overcharge, over-discharge, overcurrent, and short-circuit conditions. 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 features an auto-wake function to minimize standby current consumption while maintaining rapid response times for fault detection.

Battery Management Feature Summary

• Integrates dual N-channel MOSFETs for high-side and low-side switching in a compact footprint
• Provides automatic wake-up capability to reduce quiescent current during sleep states
• Delivers multi-layer protection including overcharge, over-discharge, and short-circuit safeguards

Battery Management Applications

• Protection circuits for single-cell lithium-ion portable electronic devices
• Battery management systems in consumer electronics such as smartphones and tablets
• Power protection modules for wearable technology and IoT devices

Battery Management Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors. Confirm the specific suffix AS-HAC-7 matches design requirements. Check for end-of-life notifications as some variants face discontinuation. Ensure ESD handling protocols are followed due to sensitive internal MOSFET structures. Validate package compatibility with PCB footprints prior to procurement.

Battery Management Selection Notes

Select this component when designing for single-cell Li-ion/Li-Po protection with minimal board space constraints. The integrated MOSFET structure eliminates external switch requirements. Consider the U-DFN2030-6 package dimensions for layout optimization. Verify that the operating voltage range aligns with the target system's power supply specifications. Evaluate thermal performance requirements based on expected load currents.
