Part Number: BQ25015 Other Parts Discussed in Thread: CC85XXDK-HEADSET-RD Hi,
I'm using the BQ25015 in a simple charge/supply application, where it is powering a small MCU (3.3V nominal) and charging a 250mAh LiPo pouch cell.
I'm wondering about how…
Part Number: BQ25015 Other Parts Discussed in Thread: BQ25120A , BQ25155 Hello,
is it possible to obtain the battery level from the BQ25015 device? If yes, can you please explain how the the pins shall be connected to an external MCU?

Part Number: BQ25015 Hello Guys,
Good day.
Just like to confirm the following regarding the DC-DC converter of BQ25015:
1) If I connect the input to a 5V USB source, then the charge process will be enabled. I´d like to know what happens with the…
Hello,
Your "Vout" ripple voltage will vary based on the components you select. The equation can be found in "DC-DC CONVERTER OUTPUT CAPACITOR SELECTION" section of the datasheet. It is equation 14.
Thanks,
Ricardo
你好，
您的 “Vout” 涟波电压将根据您选择的组件而有所不同…

Dear all,
The DC/DC output is enabled through the EN pin. I have an MCU connected to the output of the DC/DC so obviously if EN isn't high, then the MCU has no power.
My idea to implement "pushbutton" enabling of the entire…
Just bumping this as I need to understand how these two enable pins interact (CE and EN). The datasheet is not clear.
I would like it to be the case that if the charging function is disabled the LDO could still operate.
Many thanks!
Part Number: BQ25015 Hello, customer evaluates the BQ25015. He measures for more than two hours the charge current is below I(TAMPER) so the tamper timer should have been expired by know and report a charge done state. Unfortunately it isn’t. The charge…
Other Parts Discussed in Thread: BQ25015 Hi,
My customer has a issue. BQ25015 stops charging before I(term) which is set by customer. It is not time out. Stat1 and 2 pin indicate "Charging done". Why does BQ25015 stop charging before I(term) which is…
Other Parts Discussed in Thread: BQ25015 , BQ24072 , BQ24040 , BQ25100 , BQ24232 , BQ25101 Hello,
I would like to charge a Lipo of 400 mAh with the BQ25015.
For this Lipo, the recommended max charging current is 400 mA.
If I set the ISET2 to high…
Other Parts Discussed in Thread: BQ25015 Hello All,
I am using the BQ25015 in our system to charge a li-ion battery and power up our board. The Rset resistor (R34 in the attached schematics) is originally
a 2.2K resistor and that worked fine but…
