Hi team,
I have a question on EN signal type with device TPS56221.
The external circuitry below looks okay, but should I guide the customer on what type of EN_0.925V_KAL_VDDA_GSER signal should be?
As per my understanding, the device won't operate if the enable signal is connected with puhs-pull type I/O, because it only operates with floating.
Please correct me if any misunderstanding here, and please leave a comment to guide the customer regarding EN signal. Thanks so much!
The en/ss is used for calibration during startup, so a pull push will interfere. Use an open drain output with a resistor in series.
