Hello.
I designed AM3359 board using TPS65910 and AM3359.
And, I have some mistakes (use TPS65910 not TPS65910A), so I will change TPS65910A.
In this case, AM3359 may not be work correctly, but PMIC itself must work correctly. Isn't it ?
But, TPS65910 didn't go ACTIVE State. (I checked Vref is 0v)
And, I changed BOOT mode 10 to 00 and 01. In BOOT mode 00, TPS65910 goes ACTIVE State, but BOOT mode 10 or 01 didn't go ACTIVE State.
So, I have question.
What is minimum condition for TPS65910 going to ACTIVE State ? (I think it may be PWRHOLD signal is in 'H' state. Other Pin is N.C like AM3359ICE Board.)
I connect control signals connectd as follows. (I refer to AM3359ICE schematic)
VCC7 (28) : +5V
VRTC (29) : +1.8V Output
INT1 (45) : N.C.
SLEEP (37) : N.C.
PWRON (33) : N.C.
BOOT1 (19) : connect to VRTC(29)
BOOT0 (26) : connect to GND
PWRHOLD (1) : Connect to AM3359 PMIC_PWR_EN (C6)
Please help me,
Thank you,
