0 描述一个微型电池充电器5V 800mA 它使用 MCP7386 (U4) 为电池充电，使用 LTC3402EMS (U2) 将电压转换为高达 5V。我决定将它用于使用树莓派零的小型凸轮记录器。该连接器提供以下电压： 1：+Vbat，电池正极 2：SW1，外部开关端子，用于将电池与升压转换器分离，从而关闭电源。它连接到与 Vbat 相同的终端。 3：SW2，外部开关的另一端。 4：+5V升压转换器的输出电压 5：地 6：接地二极管 D1、D2、D5 用于显示电池的状态。连接器 J4 是一个微型 USB 连接器，用于提供电压和为电池充电。物料清单如下： "RefDes","值","模式" "C19","100nF","CAP_0603" "C20","470nF","CAP_0603" "C21","100nF","CAP_0603" "C22","10uF","CAP_1206" "C23","100u","CAPAE-5.3x5.3h7" "C24","100nF","CAP_0603" "C25","100nF","CAP_0603" "C27","100u","CAPAE-5.3x5.3h7" "C28","100nF","CAP_0603" "D1","","DIO_0603" "D2","","DIO_0603" "D3","","SMB" "D4","","DIO_0603" "D5","","DIO_0603" "D6","","SMB" "D7","","SMB" "J4","","934" "J5","","HDR-1x6T/2.54/15x2" "L1","","SRP7030F" "Q1","","SOT23" "R13","6.19k","RES_0603" "R14","7.3k","RES_0603" "R15","10k","RES_0603" "R16","6.19k","RES_0603" "R23","6.19k","RES_0603" "R24","2.2k","RES_0603" "R25","1.19k","RES_0603" "R26","0R","RES_0603" "R27","10k","RES_0603" "R30","10k","RES_0603" "R31","6.19k","RES_0603" "R32","6.19k","RES_0603" "R33","6.19k","RES_0603" "R34","6.19k","RES_0603" "TP1","","测试点" "TP2","","测试点" "TP3","","测试点" "U4","","SOJ-16/8.65x1.27" "U5","","MSOP-10" PCB+原理图 0 一个微型电池充电器 5V 800mA-gerber.zip 56.59 KB , 下载次数: 0
