XB7608AJ lithium battery protection IC CPC5

Description

XB7608AJ lithium battery protection IC CPC5 Product Description The XB7608AJ is a highly integrated single-cell lithium-ion / lithium-polymer battery protection IC. It includes internal MOSFET switches and built-in detection logic to protect the cell from overcharge, overdischarge, overcurrent, short circuit, and reverse connection conditions. Only one external capacitor is generally required, which makes it suitable for compact battery packs. It uses the CPC5 (compact) package to minimize space usage in battery modules. Key Specifications & Features These are the typical and guaranteed values at 25 °C, unless otherwise noted: Protection & Detection Voltages Overcharge detection voltage (VCU): ~ 4.25 V to 4.35 V Overcharge release voltage (VCL): ~ 4.05 V to 4.15 V Overdischarge detection voltage (VDL): ~ 2.30 V to 2.50 V Overdischarge release voltage (VDR): ~ 2.90 V to 3.10 V Current Protections & Limits Overcurrent / discharge detection current (IOV1): ~ 9 A Load short-circuit detection (Ishort): typically higher current threshold (very fast) On-Resistance & Internal MOSFETs Equivalent FET on-resistance, RSS(on): ~ 15.5 mΩ (typical) Quiescent / Standby Currents Operating current (normal mode): ~ 3.5 μA typical Power-down / standby current: ~ 1.6 μA typical Package & Operating Conditions Package: CPC5 Operating ambient temperature: –40 °C to +85 °C Maximum junction temperature: 125 °C Storage temperature: –55 °C to +150 °C Maximum VDD pin voltage: –0.3 V to 6 V (absolute max)
