The LDO should be fine to use in theory. It may be that the external supply is initializing too slow or too late.
XREADY indicates that the device is not initializing properly and the supply not powering the pin in time could explain the fault…
Part Number: BQ76930 Other Parts Discussed in Thread: BQ78350-R1A , , MSP430FR6989 Hi,
I am considering to use the BQ76930 cell battery monitor for a configuration of parallel cells, I want to use it with the BQ78350-R1A to form a complete BMS.
Part Number: BQ76930
The customer design with two BQ76930 cascaded for 20S, t he 6th and 7th series may be damaged during the process of plugging and unplugging cables.
The failure screen as below:
Plug in and out the cables of J2 and J3 at the icon…
I would imagine that you would need to calculate an offset. To calculate an offset you would need to take the voltage at two known voltage references. Then calculate the slope and see what is the offset.
This is assuming that the error in…
Part Number: BQ76930 Other Parts Discussed in Thread: SN65HVD1050 , BQ78350 Hi
My customer has questions as below.
1. BQ76930 doesn't seem to support CAN communication. Do I have to use a separate receiver to communicate with CAN?
How about using…
I take the measurement from Cell8 connection using ammeter this pin also source of the power of the PCBA.
The power consumption on the other pins(Cell1...cell7) was ignored.
Part Number: BQ76930 I am using this IC for my BMS and found an uncertain behavior at -20 deg.C. When I am using my BMS at -20deg. C I see a jump in my NTC from -20deg. to -6degC when I change my supply voltage from 48V to 42V.
