PQ5617E

High Accuracy 1 Cell Li-ion/Li-polymer Battery Protector with Control Pin

PQ5617 series are single cell Li-ion battery primary protection IC. It monitors the battery voltage and current, provide accurate protection and recovery threshold and control the external CHG and DSG FET to provide full array protection. The current is monitored via the voltage across the external sense resistor. For better system thermal performance, PQ5617 could enable the use of low sense resistor to reduce the power dissipations. PQ5617 is available in DFN6L and DFN8L package. The host can control the device to enter different modes by tuning the control pin voltage. Host control functions include: - Function Set A: Secondary UV mode + Ship mode + Shutoff mode - Function Set B: Charging off mode
