I'm using a tps62736 and I want to use the VIN_OK to tell the MCU that the battery need to be charged or not. I'm using a LiPo (4.2v to 3.5v) and a Vout of 3V. The maximum high inout voltage on the MCU is Vdd+0.3 = 3.3V and only now I noticed I connected the VIN_OK to a MCU inout. I haven't used that particular MCU IO yet so I don't know if I blow it already or not but what should I do to connect it to MCU?
Is a voltage divider the only option? My circuit use 20uA when sleeping and it is most of the time, use a voltage divider will increase the consunption :s
