BQ2947
Overview
The BQ2947 family is an overvoltage monitor and protector for Li-Ion battery pack systems. Each cell is monitored independently for an overvoltage condition.
- 2-, 3-, and 4-series cell overvoltage protection
- External capacitor-programmed delay timer
- Factory programmed OVP threshold (threshold range 3.85 V to 4.6 V)
- Output options: active high or open drain active low
- High-accuracy overvoltage protection: ±10 mV
- Low power consumption ICC ≈ 1 µA (VCELL(ALL) < VPROTECT)
- Low leakage current per cell input < 100 nA
- Small package footprint - 8-pin WSON (2.00 mm x 2.00 mm)
