Part Number: BQ76920 Here is my schematic so I know how the cells are arranged.
Here is what I'm setting up:
Overvoltage to 4.2V
CELLBAL1 to 0b00010111
My issue is that right when I hit the 4.2V mark on one of my cells, the overvoltage fault kicks…
Hello Luis. Thanks for your reply.
Luis H. S. said: The TIDA-01093 has some discussion and circuits showing how load/charger detection can be achieved using this configuration. These circuits however interface with a host MCU to make decisions. If only…
Part Number: BQ76920 Hi, Need verfiication. I will be using BQ7692006PWR battery monitor to fullfill following of my requirements:
Will be designingr BMS for 3S1P 18650 Battery Pack 11.1V.
The board will have over charging protection, balance charging, over…
Part Number: BQ76920 Other Parts Discussed in Thread: BQ40Z50 Hi Team,
I'd like to ask you about the battery monitor and fuel gauge. Considering BMS design of the battery monitor and fuel gauge for battery pack(18650 cell size, 4S/1P configuration)…
Part Number: BQ76920 Hi,
We are considering BQ76920 as AFE for our BMS application .
We need to control (ON/OFF) load current above 300A (100 to 600A) for which we are using low side back to back connector MOSFET in parallel combinations .
Total MOSFET…
Part Number: BQ76920 Using the BQ7692006PWR configured for an over current trip point of 8.25A in 8mS I can not get the fault to occur. The BQ7692006PWR is returning a current measurement of -9.79A over I2C. The circuit is driving a PWM'd resistive load…
Part Number: BQ76920 Other Parts Discussed in Thread: EV2400 Trying to talk to this device over I2C, getting NACK. The full part number is BQ7692006PWR, so the address should be 0x18 with no CRC.
Any ideas?
