I am designing the BEC power of an ESC for a drone application.
Design parameters are as follows:

Input voltage: 3S-6S LiPO (11,1V-22,2V)

BEC (switch- mode): 5V-8V Adjustable (Step: 0.1V), 7A/18A Cont./Peak.

Does Infineon have a solution for BEC power? If so, please suggest me a solution that meets the above parameters.

Hi Infineon

When MCU（-TC397） stop feed watch dog, ROT will high->low，and ss1 will low after 5us.

In my design I need SS1 go low earlier than ROT（1us is enough） If any ways can adjust ROT and SS1 timing? 

Can I use RC circuit make ROT  delay 1us? Is there any bad effect? 

Does the Infineon TLE935xB series comply with the following items?

• CiA-601-4
• Passed C&S group GmbH IOP test

Also, for the TLE937x series, although CiA-601-4 compliance is mentioned in the datasheet, has it passed the C&S group GmbH IOP test?

Hi,

I came across Current transition rise/fall time parameter in one of the Infineon Buck regulator IC datasheet(TLE8366).

Can you explain what exactly it mentions?

Hello Team,

We are using TLF35585 IC with TC36xx microcontroller. And we are reprograming the Application from the boot loader.

As we understood from the PMIC user guide, to reprogram we need to enable MPS feature through SPI command, so that PMIC would ignore the WWD and error monitoring pulse.  once flashing done successfully, we disabled the MPS, and initiated the soft reset on microcontroller (PMIC is not reset).

Once after the new Application starts running on microcontroller, we are observing some errors in status flag of PMIC related to WWD and error monitoring, we were not expecting this errors as we already disabled the MPS from bootloader after flashing.

After the hard reset (reseting micro + PMIC) we are not observing any error related to wwd and error monitoring.

Could you please confirm is this expected behavior. and also please let us know if there is any way we can reset the PMIC through microcontroller (either through SPI command or PIN)...?
