Part Number: BQ24072T Hi
I am evaluating a device to charge a single lipo cell and BQ24072T is my favorite by now. My Question: If no load is connected (i_load approx. 1uA) and there is no source at IN, how much current does the BQ24072T draw from the…
Part Number: BQ24072T Hi,
I have a questions about the BQ24072T :
I don't have output = Vbat + 225mV as datasheet say.
Actually, with a Vout = Vbat
If I only put the Vin, (no battery) Vout is approx 600mV, If I put a battery and remove the…
Part Number: BQ24072T Hi,
I want the BQ24072T to charge between 5°C and 40°C.
According to the sensor datasheet, R_Cold is 22.02kOhm and R_Hot is 5.827kOhm. I have calculated the following values:
R6: 31,7k (Used value is 31.6k)
R7: 20.3k
R8=…
