Hi Many,
I am afraid 6 MOSFETs can't handle 200A load because large MOSFET conduction loss. You need to add more MOSFETs to achieve this(maybe ten pairs - 20 MOSFETs and above). You also need to optimize the driver circuit for stronger driving capability…

Hello experts, I want to allow the MCU to both shutdown and wake up the AFE using the GPIOs of the MCU. Please tell me if the below circuits (taken from different ref…
OK thanks, so let's short them. Our design is quite similar to this TIDA: https://www.ti.com/tool/TIDA-010247 This design has an added balancing circuitry compared to EVM. Can it also be shorted externally at the terminal blocks?
Hello Pooja, The BQ76952 is stackable as well. Please refer to this application note, Design Considerations of Stacked BQ769x2 With High-Side N-MOSFET , with the TIDA-010247 reference design. Best Regards, Alexis
Hello Dimple, As mentioned in the diagram, you would want to change the resistor out to adapt to different PACK voltages. Section 3.3 Test Setup, Section 3.4 Test Results, and Figure 3-17. 120V On-PACK Port – Bottom AFE Maximum Voltage in the Design Guide…
Hi Alexis, I disable PREDISCHARGE as you suggested in it resolved my problem.
I have however follow up question in this context: Our final design will be similar to TIDA-010247, with parallel FET setup. The TRM says the PREDISCHARGE FETs are not useful…
Hello Dimple, We have this Design Considerations of Stacked BQ769x2 with High-Side NFETs application note that references the TIDA-010247 reference design that could help. We also have this How to Stack Battery Monitors for High-Cell-Count Industrial…
Part Number: BQ76952 Other Parts Discussed in Thread: BQ76942 Tool/software: In reference to TIDA- 010247 we are implementing a design with 6 Charge and 6 Discharge FETs of total gate capacitance 51.6nF but after implementing the reference Multiple FETs…
Hello Fairuz, This device is built with integrated high-side FET drivers; however, our device can also be configured to drive low-side FETs as well. We have some resources here that may help with your decision:

Part Number: BQ76942 Other Parts Discussed in Thread: TIDA-010247 Hi,
According to TIDA-010247 ref design REGIN input received voltage from B+ (the topmost battery) through transistor-based voltage converter circuit.
Why not to take voltage from…
