AP9211S-AE-HAC-7

AP9211S-AE-HAC-7 is a 1S Li‑ion/Li‑polymer battery protection IC from the AP family. It provides safe protection for a single-cell pack by controlling external MOSFETs to disconnect the cell during fault conditions.
Key protections:
- Overcharge protection (OCV cutoff)
- Overdischarge protection (UVLO)
- Overcurrent/short-circuit protection (fast trip)
- Optional/typical overtemperature protection
- Auto-retry after fault conditions clear
How it works:
- Monitors cell voltage and pack current via an external current path.
- Drives an external pair of MOSFETs to open/close the discharge/charge path.
- Latches off on fault and auto-recovers when normal conditions return.
packaging and use:
- “AE-HAC-7” denotes a specific package/variant of the AP9211S.
- Requires external MOSFETs and a sense resistor; typical 1S pack layouts place FETs between B− (battery negative) and P− (pack negative).
- Commonly used in 1S battery packs for mobile devices, power banks, and small electronics.
For exact electrical specs, pinout, and recommended application circuits, consult the official AP9211S data sheet.

Here are the typical features of AP9211S-AE-HAC-7 (single‑cell Li‑ion protection IC) in brief:

HAC-7 package — a 7-pin HAC/SOP‑style surface-mount package used for the AP9211S-AE-HAC-7.

AP9211S-AE-HAC-7 is a 7-pin Li-ion battery protection IC in HAC-7 package.
- Pin count: 7 pins.
- Function: Single-cell Li‑ion/Li‑polymer protection IC that monitors cell voltage and current and drives dual MOSFETs to protect against overcharge, overdischarge, overcurrent/short-circuit. It provides separate charge and discharge control outputs to the FETs (COUT and DOUT) and interfaces to the battery terminals for sensing and power.
Typical connections (pin roles; exact pin names vary by package): VDD (battery positive supply), VSS (ground), S (sense), COUT (charge FET gate drive), DOUT (discharge FET gate drive), B− (battery negative), P− (pack negative).

- Manufacturer: Anpec Electronics Corporation (Anpec).
- Company type: A Taiwan-based fabless semiconductor company that designs and markets analog, power-management, and battery-management ICs.
