Part Number: AM3352
Other Parts Discussed in Thread: TPS65910
Hi
Our customer is considering to use AM3352 and TPS65910A31A1.
So they are referring SWCU093F to see connection and power sequence.
Their application operates without any low power mode and does not require RTC.
So they don't use internal RTC and OSC1.
Their configuration is following.
-There is no external power switch
-OSC0_IN is used for external clock (24MHz)
-OSC1 is not used
-The time information is obtained from external RTC IC
-RTC_KALDO_ENn is connected to VRTC (1.8V)
-RTC_PORz is connetected to GND
-EXT_WAKEUP is connected to GND
1.
In this case, could it be possible to release PWRHOLD by PMIC_PWR_EN to
start power sequence?
2.
Should we implement RTC feature (internal RTC or OSC1) on AM3352
to make correct power sequence from PMIC?
3.
Do you have solution to make power sequence for AM3352 and PMIC without
RTC?
BestRegards
