CXPR7160A CXPR7160B CXPR7160C提供完整的锂离子充电器保护，防止输入过电压、电池过电压和充电电流限制。当输入OVP或电池OVP超过阈值时，IC通过关闭内部开关来切断充电系统的电源。当通过内部开关的电流超过电流极限阈值时，电流将被钳制在一个恒定的水平，以提供恒定的电流供电池充电使用。所有保护装置也有防电压尖峰或电流瞬变引起误触发的脱胶时间。CXPR7160A/B/C集成了P-MOSFET和体二极管反向保护，以取代Infineon ULC2手机充电器功能的外部功率双极晶体管和肖特基二极管。当CHG_DET电压降至VBAT+20mV以下时，内部电源选择电路将反转主体二极管的端子，以防止反向电流从电池流回到CHG_DET引脚。CXPR7160A/B/C为英飞凌ULC2手机提供了完整的锂离子充电器保护，并为其保存了外部MOSFET和肖特基二极管。以上特点和小包装使CXPR7160A/B/C成为手机应用的理想部件

产品概述 返回TOP
The CXPR7160A CXPR7160B CXPR7160C provides complete Li+ charger protection against Input over-voltage, battery over-voltage, and the charge current limit. When the input OVP or the battery OVP is over the threshold, the IC removes the power from the charging system by turning off an internal switch. When the current via the internal switch surpasses the current limit threshold, the current will be clamped in a constant level to provide a constant current for battery charging usage. All protections also have deglitch time against false triggering due to voltage spikes or current transients. The CXPR7160A/B/C integrates a P-MOSFET with the body diode reverse protection to replace the external power bipolar transistor and Schottky diode for charger function of the Infineon ULC2 mobile phones. When the CHG_DET voltage drops below VBAT+20mV, the internal power select circuit will reverse the body diode’s terminal to prevent a reverse current flowing from the battery back to the CHG_DET pin. The CXPR7160A/B/C provides complete Li+ charger protections and save the external MOSFET and Schottky diode for the Infineon ULC2 mobile phones. The above features and small package make the CXPR7160A/B/C an ideal part for cell phones applications
