AP9211S-AE-HAC-7

AP9211S-AE-HAC-7 is a single‑cell Li‑ion/Li‑polymer battery protection IC (AP9211S family) designed to work with two external MOSFETs. It provides essential protection: overcharge, overdischarge, short‑circuit/overcurrent, and over‑temperature, plus fault indication and auto‑retry. The device monitors cell voltage and temperature (via a thermistor) and drives the charge/discharge FETs to isolate the cell when a fault occurs. The HAC‑7 suffix denotes a specific RoHS‑compliant package variant. It is commonly used in compact battery packs for consumer electronics, wearables, and portable tools. For exact electrical specs, thresholds, current limits, and pinout, consult the latest AP9211S datasheet.

AP9211S-AE-HAC-7 is a 1-cell Li-ion/Li-polymer battery protection IC in a 7-pin HAC package. Key features:
- Dual MOSFET control for both charge and discharge paths.
- Overcharge protection with disconnect when Vbat reaches the upper threshold.
- Overdischarge protection with reconnect when voltage recovers above the lower threshold.
- Overcurrent/short-circuit protection with fast response (both charging and discharging directions).
- Overtemperature protection with shutdown at high temperature.
- Auto-recovery after fault is cleared (safe state restored automatically).
- Low quiescent current for extended standby life in portable applications.
- Suitable for single-cell battery packs with simple PCB integration; compact 7-pin package.
Note: For exact electrical thresholds, timing, and package details, please refer to the official datasheet.

- Pin count: 7 pins (SC-70/7-pin HAC package).
- Function: AP9211S-AE-HAC-7 is a single-cell Li-ion/Li-polymer battery protection IC. It monitors cell voltage and current and drives external MOSFETs to disconnect the cell under fault conditions, providing overvoltage, undervoltage, overcurrent/short-circuit protections (with auto-recovery).
