Part Number: BQ2970 Other Parts Discussed in Thread: TPS63900 , TMP303 Tool/software: Hello,
We need to certify our design as intrinsic safe design. Battery will not be charged
Can you please review the flow, so we can proceed with schematics?
Requir…
Part Number: BQ2970 Tool/software: I am working on a design that is going to use two single cells in parallel with just a positive and negative terminal connection. I want to use some kind of protection so I thought about using the BQ29703DSER. In theory…
Hello Southern Engineer,
Southern Engineering said: 1) When one IC enters over-discharge status, is it a risk that this pull of that IC's V- pin to BAT can trigger discharge overcurrent status for the other IC, by pulling the V- pin of that other IC high…

Hello TI Community,
I am using the BQ29700 single-cell lithium-ion battery protector IC in a tag device that can enter a dormant state for several months. During this time, the battery voltage may drop below 2.8V . However…
Part Number: BQ2970 Tool/software: Hi,
The pin descriptions in chapter 5.1.4 and 5.1.5 of the BQ2970 datasheet the following is stated:
"A 5 MOhm high impedance resistor is connected from DOUT (COUT) to VSS for gate capacitance discharge when the…
Part Number: BQ2970 Tool/software: Hi TI,
I have a question about the page 16 note about shorting the V- and VSS pins together to enable the discharge circuit:
How low a resistance of a short is required and how long must it be applied? Is this something…
Part Number: BQ2970 Tool/software: I am using LTC4124 as wireless charging IC. And 40mAH Lithium-ion battery. Charging voltage is set at 4.2V and Charging current is fixed at 10mA. the issue i was facing was there was no undervoltage protection for battery…
Tool/software: I am hoping to find a battery protector IC for a single 3.2V LiFePO4 cell, but looking at the single cell battery protection ICs here , none seem appropriate.
For a single 3.2V LiFePO4 cell, these parameters are appropriate...
Over-charge…
