hi,
I'm having a problem debugging TLF35584
My configuration of the DEVCTRL register is shown below
The configuration of the DEVCTRLN register is shown in the following figure
The result now is:
QT2 has no current output
QT1 has no current output
QOC has current output
QVR has no current output
Currently in NORMAL
I don't understand why I only turned off the current output in QVR, but there is no current output in QT2 and QT1
Solved! Go to Solution.

Hi Xiaoxuan,
QVR is the voltage reference and QT1/2 are voltage trackers.
The trackers get their reference value from the reference voltage source (QVR). The output voltage of trackers 1 and 2 is following the reference voltage source Volt_Ref with a small drop.
If you disable QVR (switch off), then QT1/2 will be 0 V as well, which leads no current output.

hi,
Thank you very much for your reply.
I have another question for you,
NORMAL-state ->SLEEP-state
NORMAL-state ->STANDBY--state
Do both of the above state transitions require the MUC to enter low power mode?
If so, how to enter low power mode? (I use TC375 chip)

Hi,
go to SLEEP or STANDBY mode need to make sure ENA and WAK=0 firstly.
Then via SPI command "go to SLEEP" or " go to STANDBY" can the device go to corresponding mode.

hello,
How do the following conditions need to be met
There is also a question: how to determine the microcontroller current consumption below the selected LDO_µC current threshold

Hi,
You can configure it with a suitable value in DEVCFG2.CTHR, if your microcontroller current consumption is above LDO_µC current threshold in sleep mode.

Hi,
The current of my microcontroller is 144mA, and the maximum current set by DEVCFG2.CTHR is 100mA. What do I need to do to make the MCU current below 100mA?

Hi,
There are several methods to reduce MCU current consumption:
1. Go to low power mode
2. Switch off communication
3. dynamic reduce frequency
4. design suitable GPIO Pin circuit.
For further help, you can post a new topic on MCU board.
