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)...?
Regards,
Manjanna B

Dear Sir/Madam,
We would like to understand more about ICE3PCS01G - VB_OK, VBTHL_EN, and VREF pins.
Can you please share a design guide with formulas that talks about how to set up external components that may be required?.

Hi All,
Im unsure if Im doing this right. I am looking for a product that replaces/is compatible with TLE6288R. As I understand , this product is discontinued right?
Thanks,
Regards.
Denis.
Show LessHello
Could you send the Gerber data for EVAL_TDA38740_3.3VOUT?
Best regards,
Hi Everyone,
We are looking to use IRPS5401 PMIC in our project. The supply voltage ratings are as below:
Input Voltage: 5V
Output1: 0.9V @ 3A
Output2: 1.5V @ 1.5A
Output3: 1.8V @ 1.5A
Output4: 3.3V @ 200mA
Kindly recommend the decoupling capacitors required for the input and output pins.
Looking forward to your quick response.

Show LessPlease provide the pspice model for the TLE4476D LDO regulator
MPS pin pulls high to 5v, configured to enter normal mode, no dog feed in normal mode, generates error back to init mode, generates reset, logic analyzer grab finds ROT pin has pull low, according to datasheet description no reset will be generated during return to init.

Show Lesshello (polite)
Recently, I was choosing a PMIC chip and found that both TLE7368E and TLF35584QVVS1 meet the conditions, but I encountered some questions about the use of both:
1. If the TLF7368E does not use LDO3, how are the FB_EXT and DRV_EXT pins connected; and if FB_EXT and DRV_EXT are shorted does it cause RO_2 to reset;
2.Can TLF35584 be used for MCU without SMU module, if so how to connect;
thanks

Show LessHello,
I have a question about a few CANbus transceivers, i am looking for a new IC to replace the TLE6251-2G with a newer IC I was looking at the TLE6251DXUMA2 but i don't fully understand the datasheet for it. The main thing that i need is a wakeup signal from the transceiver to and external MCU that can wake the MCU. the TLE6251-2G has the NERR pin but the TLE6251DXUMA2 does not. I have seen that the TLE6251DXUMA2 has the bus wakeup and i see that it does something with the STB pin but does this pin give a signal when a wake-up frame is detected?
Kind regards
