Part Number: BQ2980 Other Parts Discussed in Thread: BQ2982 Hello E2E Experts,
Good day.
I have two questions:
1. For BQ2980/ BQ2982 the OVP triggers at 4.475V. For the LiFePO4 battery, the nominal voltage being 3.6V, will this IC be able to protect…
Part Number: BQ2980 Hi Team,
I want to use the BQ298000RUGR to protect my 3.7V lipo battery, but I don't understand the schematic on the datasheet.
If you can you tell me, what the value of RSNS should be and what "Scale RC values for system reset…
