Hi, my name is David. It's my first time using the BQ25010RHLR.
I use the Nordic's nRF52832-QFAA MCU. VOUT is expected to be 3V and this will be fed to the MCU.
The MCU has 13k Ohm internal pull-up resistor. I connected the STAT1 and 2 to the MCU.
The numbers inside the brackets are the size metric (1.0mm x 0.5mm 1005, etc).
I wish the DC-DC converter to activate regardless of the USB power input. I want it to work even if the battery isn't charge via USB.
I only use the USB charge. So I tie the AC pin with a pull-down resistor.
V_USB will range to 4.2~5V. It's the power pin of a Micro-B USB pin.
I will create a Test Point to check PG.
I use a Li-ion 3.7~4.2V battery. V_BAT is connected to the positive side of the Li-ion battery.
So my questions are,
0) Is it fine to connect the battery pin to the EN(DCDC enable) pin?
1) Does my resistor/cap configuration for getting 3V as output is correct?
2) The VOUT will be 3V. Is the STAT1 and 2 pin is also 3V when it is high?
