    LDO crash when Lipo reaches full charge with USB still powering.

    Hello, I'm just now getting into creating PCB's as a hobby, and created a little board that simply consists of a BLE module powered by a tiny Lithium polymer battery (40mah). Since the max operating voltage of the module is 3.6V, I also have an LDO that will drop the voltage down to 3.3V...

    Need help finding BMS for this lipo battery.

    Hi, I'm going to get this 4S 7AH lipo battery for an RC project. I need a BMS for it that prevents short circuits and overdischarge. All of the BMSs I can find have a cutoff voltage of 2.5V! This doesn't seem good, as isn't it supposed to cut off at 3V to be safe and maintain its capacity!? So...

    Charging & Powering Board Design

    Hi, I am looking to power a attiny85 with a LiPo battery, but I would like to have the ability to charge it through the same board. At the moment I am looking at the TP4056 with the FS312F-G and FS8250. So my question is, can I connect the battery to the attiny85 through the battery charger...

    Designing power bank circuit with BQ24195.

    I want to design a power bank control board for a single-cell lipo battery. The IC I have selected is BQ24195 by texas instruments. I think it is perfect for what I need. It comes with charge control, boost, voltage protection, I2C control, and many other features. But I have some doubts about...
