BQ79616PAPR

BQ79616PAPR is Texas Instruments’ automotive-grade, 16‑cell battery management IC (BMS) in a PAPR package. It combines cell-voltage sensing, pack current/temperature monitoring, protection logic, and gate-drive outputs for external MOSFETs, all in one device.
Key points:
- Monitors up to 16 series cells (high-voltage Li‑ion/LiFePO4 packs)
- Inputs for multiple cell voltages, pack current sense, and temperature
- Protection: UV/OV, OT, short‑circuit, overcurrent, and fault latch with safe‑start sequencing
- Drives external protection/balance FETs and provides cell-balancing control (typical passive balancing)
- Internal control logic and a host MCU interface (serial/SCI-like) for status, configuration, and fault reporting
- Automotive-grade, with robustness for EMI/ESD and fault management
- Packaging variant PAPR; check datasheet for exact pinout, voltage ranges, and balancing specifics
Common uses: EV/HEV battery packs, energy storage systems, and other high-cell-count Li‑ion packs. For exact features and limits, consult the BQ79616PAPR datasheet.

Here are the typical features of TI bq79616PAPR (16‑channel Pack Protector):
- 16 cell‑voltage sense channels for high‑voltage battery packs (up to ~68V pack)
- Pack current sensing and protection for charge/discharge paths
- Per‑cell undervoltage/overvoltage protection and pack‑level OV/UV protection
- Fast overcurrent/short‑circuit protection (discharge and charge paths)
- Temperature monitoring (NTC input) with overtemperature protection
- Precharge/control of external MOSFETs with safe ramp/soft‑start
- External N‑MOSFET gate drivers for full series FET stack protection
- Fault latch with status outputs and auto‑retry/restart behavior
- Diagnostics and host communication interface (SMBus/I2C‑like or SPI‑style)
- Programmable thresholds, timing, and protection parameters
- Low quiescent power and standby modes
- Automotive qualification and ESD protection (industrial/auto temp range)
Note: exact interface, packaging, and parameter values can vary by revision; consult the TI datasheet for the precise PAPR variant.
