一,产品概述(General Description)      jNA嘉泰姆
jNA嘉泰姆
      The CXLB7341CS is a complete, cost effective, high- efficient solution for Li-Ion Battery Powered Mobile Supply.jNA嘉泰姆

VBAT is a complete constant-current/constant voltage linear charger for one cell lithium-ion battery. The chargejNA嘉泰姆

current of pre-charging and constant–current charging is adjustable and it can be programmed to 1A. An external sensejNA嘉泰姆
resistor sets the charge current with high accuracy.VOUT5 (5V) is a step-up DC/DC converter with internal power MOSFETs.jNA嘉泰姆
It achieves 2A (with 2318 NMOSFET) continuous output current over a wide input supply range with excellent load and linejNA嘉泰姆
regulation. In addition, the CXLB7341CS can be used as a flashlight.jNA嘉泰姆

The CXLB7341SC is available in a low profile TSSOP-16L package and The CXLB7341CSS is available in a low profilejNA嘉泰姆
