  • 充电过程 IP2365通过检测FB引脚的电压,来确定充电状态: 如FB电压VFB <1.5V,进入预充电状态,以100mA左右电流对电池进行涓流充电; 如FB电压1.0V<VFB <2.1V,进入恒流充电状态,以设定的恒流充电电流充电; 如FB电压VFB >2.075V,进入恒压充电状态,IP2365会每隔30秒,停止充电(充电电流降为0) ,然后 检测FB电压,如VFB >2.075V,则认为电池已充满,结束充电。否则,继续充电。 如电池充满后,检测到FB电压VFB <2.
  • 充电电流 IP2365可以通过外接电阻来调整恒流充电时的充电电流; IP2365可以通过外接电阻,来分别设臵电池端或输入端的充电电流; IP2365可以通过在ICHG引脚(第3脚)上,接不同阻值的电阻RICHG, 来设臵恒流充电电池端电流ICC_BAT (精度± 10%),关系如下: ICHG RICHG RICHG设置恒流充电 电池端电流 ICC_BAT=75K / RICHG RICHG ICC_BAT 25K 3.0A 37.5K 2.0A 50K 1.5A 75K.
  • 电效率会降低,需要适当降低充电电流设臵; 充电 NTC IP2365支持NTC保护功能,通过NTC引脚检测电池温度高低,当检测温度超过设定的温度时,停止充 20uA R2 RNTC VL=1.44v VH=0.38vNTC MT比较 器 如果测量到 NTC pin上电压高于1.44v,则表示电池温度过低 如果测量到NTC pin上电压低于0.38v,则表示电池温度过高 HT LT 如果测量到 NTC pin上电压低于0.56v,则表示电池温度偏高 VM=0.56v 当 NT.
  • VINSEN 引脚可以作为使能引脚,接大于1.5V 的信号,正常工作;小于1.3V 的信号,停止 充电,进入standby; VINSEN IP2365 RVS2 RVS1 VIN RVS1、RVS2设置输入欠压值 VVIN-CV=1.5V X(1+RVS2/RVS1) 保护功能 IP2365 具有输入过压保护功能: 当VIN 上升超过27V,IP2365 检测到输入过压,停止充电; 当 VIN 再次下降到25V,IP2365 才认为输入正常,重新开始充电。 通过定制,输入.

Engineering review checklist

  • Verify forward current and voltage, optical bin, wavelength or color coordinates and viewing geometry.
  • Derate light output and lifetime for junction temperature and the actual PCB thermal path.
  • Confirm polarity, footprint, reflow profile and moisture-sensitivity handling before production.

Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
