If one cell reaches an • Low Power Consumption I CC < 2 µA overvoltage condition, the protection sequence [VCELL(ALL) < V(PROTECT)] begins. The bq2941x device starts charging an • Fixed High Accuracy Overvoltage Protection external capacitor through the CD pin. When the CD Threshold pin voltage reaches 1.2 V, the OUT pin changes – bq29410 = 4.35 V from a low level to a high level. – bq29411 = 4.40 V – bq29412 = 4.45 V – bq29413 = 4.50 V – bq29414 = 4.55 V – bq29415 = 4.60 V – bq29419 = 4.30 V • Programmable Delay Time of Detection • High Power Supply Ripple Rejection • Stable During Pulse Charge Operation • 2nd-Level Overvoltage Protection in Li-Ion Battery Packs in: – Notebook Computers – Portable Instrumentation – Portable Equipment The bq2941x is a secondary overvoltage protection IC for 2-, 3-, or 4-cell lithium-ion battery packs that incorporates a high-accuracy precision overvoltage detection circuit. It includes a programmable delay circuit for overvoltage detection time.
