Part Number: BQ76200 Tool/software: In this High side N-Channel FET Driver IC, I am experiencing one issue. The Pin 16 (CHG) is showing to be internally shorted to Pin 2 (BAT). Want to understand how can this happen, under what conditions?
Part Number: BQ76200 Tool/software: Can you confirm the chg/discharge/pchg FET can be enabled at the same time ?
I'd like to enable pchg FET for precharging capacitive load and subsequtenly enable the chg+dischg FETs simultaneously (without explicitly…
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 ) ,

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…
