Part Number: TPS53681 Tool/software: The TPS53681 is used in 4+2 configuration.
The pins APWM5, APWM6 and ACSP6 are floating, ACSP5 is connected to V3P3. Please confirm if that's correct.
Have attached a screen shot of the same.
Thanks,

Hi Jiaolong,
It sounds like one of the powerstages may have been damaged in testing. The temperature output pins are also the fault reporting pins, so not connecting them will not allow the controller to turn them off when there is a fault. Having a fault…
Part Number: TPS53681TPS53681RSBR pins ATSEN and BTSEN, 36, 35 are marked as output pin on page 5 table; other data/statements in the datasheet lead to viewing this pins as Inputs. Can the pin time be confirmed.
Hi Yihe,
Please accept my apologies, you can close this ticket. We've found a bug in our smbus block write implementation, I thought this had been checked but it seems this was not the case. NVM writes are working successfully now.

Part Number: TPS53681 Dear Team,
customer is using TPS53681 for Radio design, and they found TPS53681 can not work at -40C.
at -40C, Vin12V, and Vout 5.35V is ok and Vout 0.85V can not work.
if TI has any solution ready to resove the issue for low temperature…
Part Number: TPS53681 Hi team,
What command will be returned if FAULT is cleared to TPS53681 through PMBUS?
After writing the 03 command on the customer's board, NACK is returned. Is it because 53681 did not receive the 03 command?
In addition, does…
Part Number: TPS53681 What is the voltage threshold for the TPS53681 AVR_EN, BVR_EN, and Reset pins? The datasheet only has recommended operating conditions of -0.1V to 3.5V.
