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?
BR,
Steven

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…

Hello E2E Experts,
Good day.
I am developing a new product that will have a plug-pack (wall-wart) as the main power supply and internal battery backup. My main DC bus will be 5V which will be used to run the unit and charge the internal…
Part Number: BQ2980 Hi
I am trying to select a ptc thermistor which protects the circuitry over 80 degrees. Our input voltage is 3.5V But I couldn't see the exactly calculation method in the datasheet. Can you please help with that?
I calculated some…
Part Number: BQ2980 I need a protection circuit for a single LiIon rechargeable coin cell, with the following requirements:
* OVP: 4.3V to 4.4V
* UVP: 2.8V to 3.0V
* OCC, OCD: target draw is under 25mA. Cell needs about 50mA max cut-off for charge and…
Part Number: BQ2980 I'm using a BQ298018RUGR in a design and seeing unexpected results. Our circuit follows the EVK design, however when our design is connected to power the protection chip draws ~130mA current, almost all of it through the BAT pin…

Hi Team,
Good day!
Our customer is designing battery protection circuitry for a single-cell 130mAh Li-Po battery. Due to its small capacity, the cell has a very low (130mA) maximum discharge current.
With this in mind, I have cal…
Part Number: BQ2980 I would like to use a push button for a reset functionality but want to ensure the device does not get into SHUTDOWN.
I was thinking about connecting CTR (with a pull down to PACK-) via a push button to PACK+. So if the button is…
