Thank you for your reply. My usage scenario is that the tps61289 operates in boost mode, with an input of 3V and an output of 17V at a current of 5A. In this extreme case, the peak current of the built-in current-limiting MOSFET in the chip will exceed…
Part Number: BQ24072 I am currently designing a product and facing a compliance challenge. During testing, we are required to short the input and output to bypass the BQ24072, resulting in current levels that exceed the specified limits. Could you please…

7.3.2 Programmable Current Limit A high-accuracy current limit allows higher reliability, which protects the power supply during short circuit or power up. Also, it can save system costs by reducing PCB traces, connector size, and the capacity of the…
Part Number: AFE5832LPEVM Other Parts Discussed in Thread: TX7332 Hi,
We are currently using the Swroop board to transmit multi-channel signals. When following the testing steps outlined in the Swroop user manual, we can observe the “Sync signal,” but we…
Thanks for the schematics. I am also not 100% sure why 7V would appear but have following suspicions for which I have some suggestions for you to implement and check
VCC/VISO Supply Decaps:
I don't see any supply decaps in the schematics - At least…
1. 2. Can you provide the load profile for me to evaluate?
3. Can you provide the load profile for me to evaluate?
4. It is ok to directly short ISP and ISN to Vout if not used.
5.
TPS55289 and TPS55287 are pin-to-pin. The only difference is TPS55289 has…
Can you provide a register dump?
Do you have a system load? Do you see this issues without a system load?
What is the battery voltage and charge current?
Do you have a current limit on the input supply?
Is this for the gate driver? You can check the supply current whether its supply current exceeds HV start-up current out of VDD, the typical value is 250uA. The gate driver VCC sink current is too large to limit the VDD rising up.
You can refer to the…
