Part Number: BQ2980 I want to use the BQ298015 as a system-side protector in a product with a replaceable 18650 Li-Ion cell.
The product should be able to turn on after inserting a full battery cell, even if there is no charger attached.
According to…
Part Number: BQ2980 I have trouble understanding the Host-controlled Shutdown function. I calculated the RC as mentioned in the Datasheet, to be above 3.6s, but even if I apply a voltage of 3.8V for longer than 10seconds, the battery protection will not…
Part Number: BQ2980 Other Parts Discussed in Thread: BQ25175 , Hi Team,
customer is looking for a protection IC with following specs. Could you please recommend a suitable solution?
Overcharge detection voltage: >4.393 (max value of BQ25175)

Part Number: BQ2980 Hi Team,
My customer is studying our BQ2980 but we found that the dimension look like doesn't match each other as below picture shown.
Could you please check whether the length of Y-axis is 1.85mm or 1.86mm(0.58 x 2 + 0.7)?
Best…
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 the…
Part Number: BQ2980 Other Parts Discussed in Thread: BQ2982 I am looking for a single-cell Li-ion protector with overtemperature protection, and have found the BQ2980/BQ2982 series devices. After looking at the datasheet, I am a bit confused about what…
Part Number: BQ2980 I've seen several places where it said that this part may not be suitable for stacking but no definitive explanation on the forum or in the datasheet.
Can this part be stacked? If not, why, and is there a workaround?
I need a 2S…
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…
Part Number: BQ2980 Hi team,
I'd like to confirm if it is fine to ground CTR pin B- if we don't need this function?
Besides, a 0.1uF filter C6 should be appropriate between pack for ESD protection?

Hi,
Below is a diagram of the question: the circuit is exactly the same as what datasheet suggest, just there are other pull down circuit (red and orange N-MOSFETs) – when other protection in the system triggers, these MOSFETs will…
