Part Number: BQ76920 Other Parts Discussed in Thread: BQ78350 Tool/software: Hello,
I have a few questions regarding a BMS design in which we use a BQ76920 AFE. It shall also be used in conjunction with the BQ78350 Controller in one design and without…
Part Number: BQ76920 the Gain and Offset values of the BQ7692003 AFE controller, Are configured at the factory is expected to remain unchanged throughout the device's lifespan? or not?
Is it any chance of changing during run time?
Part Number: BQ76920 Hello Expert,
We have a requirement to battery NTC which is connected to BQ76920 to also be parallel read by Host controller ADC interface.
we have connected NTC to TS1 pin of BQ76920 and same is also connected to ADC of host MCU…
Thank you Verboncoeur.
"The companion MCU completely controls the cell balancing."
So when using the BQ76920 with it's companion MCU, from which interface should I read battery info (SOC etc) from? From the bq76920's I2C or the companion MCU…
Part Number: BQ76920 Tool/software: When using the formula from the datasheet:
V25 = 1.200 V (nominal) VTSX = (ADC in Decimal) x 382 μV/LSB TEMPDIE = 25° – ((VTSX – V25) ÷ 0.0042)
The value isn't inside the expected range. An…
Part Number: BQ76920 Other Parts Discussed in Thread: BQ76942 Our design has a hardware watchdog to reset the main CPU in case the software is not responsive. This watchdog also asserts the ALERT pin to make sure the BQ switches off the FETs, which is…
Part Number: BQ76920 Hi I have some questions about BQ76920. 1. Is it possible to change Q2 from MOSFET to Transistor? (To reduce Charger voltage from VBATT + VGSth(2.5V) to VBATT + VBE(0.7V)). 2. Any effects if I change according to No.1?
Best Regard Watchaphong…
Part Number: BQ76920 In building a Cypress PSoC project, our entire project uses a 'Gnd' in many places.
In adding a BQ76920 and LiFePO4 4 cell battery pack is presenting problems.
Namely, the TI part (BQ76920) simplified schematic indicates 'Gnd…
Part Number: BQ76920 Hi
The customer design with BQ76920. The voltage of the first two cells is very small in one cell and very large in the other cell. They used an oscilloscope to see that the collected voltage has stabilized.
But the AFE collect the…
Part Number: BQ76920 Other Parts Discussed in Thread: BQSTUDIO , BQ76952 Hi
The customer design with BQ76920, BQ76920 battery voltage will drop when the load is connected, but the voltage read by BQStudio cannot collect this.
The waveform as below:
There…
