I am considering this part bq24075 for my load 5V with 1.2A peak. The Vin is 5V with 1.5A peak.
I want to have the battery charging and 5V output at the same time, when there is a 5V Vin. But I need to have a switch to control the Vout ON/OFF, when there is no input.
I have a question here as:
1. If there is no input, the Li-ion battery can only output ~3.7V? Do I need to add a boost circuit to boost 3.7V to 5V for my load?
2. For the question 1, if there is much better parts for this application?
3. Can I use the pin SYSOFF of the bq24075 for the switch control the ON/OFF
4. If bq24075 support battery over dis-charge protection? If no, any parts support this function?
