Part Number:INA181
Please help to check the design for 19V@6.3A input . if 6m Ohm Rsense is ok for this design ?
it used to sense 19 input current ,and if system sinks current exceed about 6.1A,We will send warning message to system.
Thanks

您好,
看附的电路图,19V的负载应该是接在+AC_BAT_SYS1上,如果是这样的话,那么这属于高侧测量电流,为了使INA181输出为正电压,INA181的IN+和IN-需互调换:
其他地方没看出问题。
