Dear Sir, I have mentioned my problems below Please reply me soon in easy description as I am from Software background and have sound knowledge of circuits.
Dear Sir, I have bought this module,
And want to power it with 3.7v lipo battery. But in the Datasheet, I have some problems to discuss with you. I am attaching two snapshots from the datasheet below.
- There is not any voltage rating of the capacitors CA , CB , 33PF , 10PF in the datasheet. So what would be the voltage rating of these 4 capacitors to choose ?
- According to the first snapshot , which one is the correct power ciruit shown below ?
- Datasheet shows CA is Tantalam capacitor. Can i use a non SMD capacitor (eg. An electrolytic capacitor) at the place of Tantalam capacitor.
- Is VBAT pin is Vcc pin, here ?
- Second snapshot states that -
“Total impedence between battery and VBAT pins shoud be less than 150mOhm”
Sir, does this power circuit follows this statement or this statement is not of much importance.
