Comment (by Terry Su):
Actually,the TEMP sensor design for Battery TEMP compare isn't used to
detect system working temp. This is feeback the ambient temperature, so we
place in very clear place (near board border)on B2 M/B. Current battery
didn't need this TEMP parameter and we didn't get any placement change for
others TEMP measure, so it's too later cut in B3-stage, because we already
release Pre-B3 PCB gerber. If possible, please define this TEMP sensor for
which detect, we'll move to correct place for detect on B3 or B4 stage.
P.S. this sensor is very rough TEMP sensor, so can't be used to accurate
measurement, it's used thermistor and sence voltage to EC AD calculate.
