Part Number: BQ2973 Hi,
We are considering to use BQ29737DSER in an existing design, but the main track would currently ground the pin that is defined as "NC" for the BQ29737DSER. The BQ29737DSER datasheet states "No Connection (electrically open, do not…

Part Number: BQ2973 Other Parts Discussed in Thread: BQ24040 Hi Team,
Can you please help check the schematic for two BQ29737 in parallel below?
The target system has got two Li-Ion Batteries. Each battery is protected with a single BQ29737. The batteries…
Part Number: BQ2973 I am developing a board using BQ29733 battery protection IC in standard configuration (as in datasheet, with the only difference that I added a 5Mohm resistor between GS of each MOSFET).
When connecting battery for the first time,…
Part Number: BQ2973 Other Parts Discussed in Thread: CSD85301Q2 Hello Expert,
Our customer have a plan to use BQ29728 or BQ29737.
As you know, there is lead time issue recently.
So our customer want to use CSD85301Q2 which is stock in TI.COM.
Below is their…
Part Number: BQ2973 Other Parts Discussed in Thread: CSD16406Q3 Hello,
I would like to run my protective circuitry design by you. I am using a 3P Grepow 704230 (835mAh) configuration that can charge at a maximum of 2505 mA (1C) and discharge at a max rate…
Part Number: BQ2973 Other Parts Discussed in Thread: BQ25175 , CSD13381F4 , Hi,
I'm using a BQ29733 (-100mV / 120mV for Vocc / Vocd) to protect a VARTA CP1654 li-ion 155mAh cell battery. The system use a 150mA charging current, and system need only 10mA…
Part Number: BQ2973 Hello,
We are currently using an 18650 Lithium Ion battery with a built-in PCM for protection. In order to be single fault safe per UL standards, we are looking to add secondary protection on the system side. The BQ297XX series looks…
Part Number: BQ2973 Hi, I am working on the design with the BQ2973 and when reviewing the footprint noticed that the footprint doesn't cover the entire pads of the component. Looking at some older datasheets with the same footprint shows a different recommended…
Part Number: BQ2973 i’m designing a circuit to protect 3-6 Volts AA batteries when a short-circuit occurs. When the short-circuit happens, another circuit(LED blinking) must be triggered and the batteries must be protected. The goal is that the LED circuit…
