Hi,
I have one question for connection for TSP65218 and AM335x.
According to the Figure 1 in Application Note " Powering the Am335x/AM437x with TPS65218", AC_DET pin is connected to system power(5.5V).
But, according to the 7.3.1.1 Power-Up Sequencing in the TPS65218 datasheet, it is wrriten in the below.
From the OFF state:
– The push-button is pressed (falling edge on PB) OR
– The AC_DET pin is pulled low OR
– The PWR_EN is asserted (driven to high-level) OR
– The main power is connected (IN_BIAS) and AC_DET is grounded AND
– The device is not in undervoltage lockout (UVLO) or overtemperature shutdown (OTS).
As to the above comment, AC_DET pin is grounded.
Which is correct? Please let me know correct handling of AC_DET pin.
I appreciate your quick reply.
Best regards,
Michi
