Part Number: BQ76200 Tool/software: Apologies for a maybe simple question.
What is the purpose of C1 and C2 (and also C3 and C4 while I'm asking) in the EVM schematic. These also appear in a bunch of other reference designs.
How are the values derived…
Part Number: BQ76200 Good morning, I have a question about the BQ76200 driver. I'm using it for a two wire system to control the charging and discharging of a battery. I separeted the two charging and discharging paths, placing two power mosfets connected…
Hello Hasan,
I understand. Yeah, we have to understand what could be pulling these pins down. Do you have any waveforms of these two pins with respect to the short-circuit?
You could increasing the capacitance on the BAT pin, for example make it 10-uF…
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…
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…
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 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…
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…
