Ryo,
If the pin is not used, then floating the pin or grounding the pin is acceptable. If the device is in triple-phase we do not want this pin to be forced to GND as the device will need to bias it at some point. If, however, it is know that SMPS457…

Part Number: TPS659037 Hi, I want to understand the input impedance of the ADC module, especially in GPADC_IN2.
From my experiment, it turns out the GPADC_IN2 channel input impedance is only around 50Kohm to ground. We have one 24.9Kohm resistor pull…
Part Number: TPS659037 Hi team,
My customer is using TPS6590379 in their design, while at power on, the LDO channels output voltage align with the default value, but the SMPS channels output voltage are all 3.3V, what could be causing this? thanks!

Hi team,
My customer wants to get the data from GPADC_IN2 continuously. The datasheet explains the instruction, which step we should loop to read the data continuously for example looping step 6-7 from the second conversion?
If…

Hi,
Please tell me when the IC of silicon revision 1.4 of TPS659037 was released.
Also is there any way to check silicon revision other than reading the DESIGNREV register?
Thanks,
Koki
Part Number: TPS659037 Hi experts,
My customer wants to change the output voltage of PMIC's LDO2. They changed the VSEL of the PMIC to 000001b ~ 111111b (0.9V ~ 3.3V), but 3.3V is always output.
Does anyone know why the LDO2 output voltage is only…
