【附图说明】
图1是本发明的手机的优选实施例的电路图。
【具体实施方式】
参阅图1,图1是本发明的手机的优选实施例的电路图。本发明的手机包括NFC芯片P、第一电容C1、第二电容C2、第一开关元件Q1、第二开关元件Q2、第一电阻R1、第二电阻R2、第一光源L1以及第二光源L2。
NFC芯片P包括控制引脚K、第一引脚VHDF以及第二引脚TVDD。当手机要靠近读卡器以作为卡使用时,NFC芯片P则要实现卡模拟功能。此时读卡器会发出一个磁场,一般该磁场匹配的频率为13.56MHZ。靠近读卡器的NFC芯片P就会通过手机的NFC天线(未图示)感应到这个磁场,从而在第一引脚VDHF上会输出第一电压。当手机作为读卡器使用时,即手机打开NFC芯片P的读卡器功能时,通过控制引脚K使NFC芯片P的第二引脚TVDD产生第二电压。并且,NFC芯片P作为读卡器功能使用时需要发出一个磁场,一般该磁场匹配的频率为13.56MHZ。第二电压同时为NFC芯片P实现卡模拟功能时的发射磁场的部分供电。一般的,NFC芯片P使用PN544芯片或PN65N芯片。
第一开关元件Q1的第一端连接第一引脚VDHF,第二端接地,第三端连接第一电阻R1的第一端。第一电阻R1的第二端连接第一光源L1的一端,即第一光源L1的一端通过第一电阻R1连接到第一开关元件Q1的第三端。第一光源L1的另一端连接第三电压。第二开关元件Q2的第一端连接第二引脚TVDD,第二端接地,第三端连接第二电阻R2的第一端。第二电阻R2的第二端连接第二光源L2的一端,即第二光源L2的一端通过第二电阻R2连接到第二开关元件Q2的第三端。第二光源L2的另一端连接第三电压。
第一电容C1的第一端接地,第二端连接于第一引脚VDHF与第一开关元件Q1的第一端之间。第二电容C2的第一端接地,第二端连接于第二引脚TVDD与第二开关元件Q2的第一端之间。第一电容C1与第二电容C2是第一引脚VDHF与第二引脚TVDD的旁路电容,保持第一引脚VDHF与第二引脚TVDD输出第一电压与第二电压时的稳定。
当NFC芯片P实现卡模拟功能时,第一引脚VDHF输出第一电压。第一开关元件Q1的第一端在第一电压的作用下导通其第二端与第三端,即使第一光源L1的一端通过第一电阻R1接地,另一端连接第三电压。在本实施例中,第三电压为手机电池VBAT的电压。因此,第一光源L1在第三电压与第二端与第三端被导通的第一开关元件Q1的作用下发光。
当NFC芯片P实现读卡器功能时,第二引脚TVDD输出第二电压。第二开关元件Q2的第一端在第二电压的作用下导通其第二端与第三端,即使第二光源L2的一端通过第二电阻R2接地,另一端连接第三电压。在本实施例中,第三电压为手机电池VBAT的电压。因此,第二光源L2在第三电压与第二端与第三端被导通的第二开关元件Q2的作用下发光。
在本实施例中,第一开关元件Q1与第二开关元件Q2为P型MOS管,第一开关元件Q1与第二开关元件Q2的第一端为栅极,第二端为源极,第三端为漏极。第一光源L1与第二光源L2为LED灯。第一光源L1的正极连接第三电压,第一光源L1的负极连接第一开关元件Q1的第三端(漏极)。第二光源L2的正极连接第三电压,第二光源L2的负极连接第二开关元件Q2的第三端(漏极)。并且,一般来说,第一电压为2.5V,第二电压为3V,第一开关元件Q1的导通门限小于2.5V,第二开关元件Q2的导通门限小于3V。
为了显示方便,可使用不同颜色的LED灯作为第一光源L1与第二光源L2,使其发光颜色不同。例如,第一光源L1为白光LED灯,第二光源L2为红光LED灯。这样,在使用时,指示灯为白光时用户便可得知此时的手机实现卡模拟功能,指示灯为红光时用户便可得知此时的手机实现读卡器功能。
通过上述方式,本发明的手机能够通过指示灯使用户轻易得知手机当前的NFC功能的类别。
以上所述仅为本发明的实施例,并非因此限制本发明的专利范围,凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
