Hello Monica,
D2 is for positive transient protections, if you want transient protections, I'd recommend to add it. The PACK+ abs max voltage is actually 100-V.
Now, the purpose of D2 is a flyback diode, so it can protect against some negative transients…
Other Parts Discussed in Thread: BQ76200 Hello Support Team ,
Currently I found issue in my Hardware , Issue is regarding Getting Voltage Between Pack+ and Pack- in totally off condition of BMS (like without Cell taping and ESP off ) ,
in resolving process…
Part Number: BQ76200 Other Parts Discussed in Thread: BQ76930 , BQ76942 Hi team,
Below is the customer schematic. They have encountered BQ76200 breakdowns recently. And the BAT,PACK.DSG,CHG pin short circuit to ground.
Customers use pre-charged MOS for pre…
Hi Hasan,
Regarding the bq76200, measuring the gate to ground could be pulling down the voltage at the gate. The charge pump is not very strong, and we've seen cases where a probe can pull the voltage down. It would be better to measure the gate to source…
Part Number: BQ76200 Dear,
I am designing a BMS with a high side driver and I am currently reading on reverse voltage protections.
Figure 4 of this application: bq76200 Reverse Voltage Considerations , suggests to add a depletion mode mosfet (Q5) to protect…
Part Number: BQ76200 Hi Team,
How should customer connect DSG_EN pin to ground if they do not use, should they connect through 10Kohm resistor to ground or should they connect DSG_EN pin directly to ground? Thanks a lot for your suppport to check.
Best…
Part Number: BQ76200 hi Sir
We have a question about t he delay time when the chg_en and dsg_en of BQ76200 are simultaneously turned on . What is the delay time?
Because the interval time is too small, it leads to the issue of MOSFET toggling when turned…
Part Number: BQ76200 Other Parts Discussed in Thread: BQ76952 Hi team,
Q: Is Rfilter or Cfilter value changeable if RC constant is saved?
D/S Table2 mentions as below. But can we change Rfilter: 100ohm to 1kohm and Cfilter: 0.01uF to 1nF without any problem…
Part Number: BQ76200 Hi
I have a query need your help.
What is the current limit of the DSG_EN pin. I do not find this value from the datasheet.
Thanks
