Other Parts Discussed in Thread: AM4378, , TPS65216
Hi,
Is there any problem with the connection below between PMIC TPS65218D0 and MPU AM4378?
[conditions]
・System Power USB5V
・No backup circuit is used
*Although the RTC timer is used, it does not operate in RTC-only mode.
- Do not attach a push button to the PMIC's PB terminal.
[PMIC:TPS65218D0]
①PB →5V pull-up
②AC_DET→GND connection
③CC→GND, IN_BU→GND connection
④PGGOOD_BU→OPEN
⑤DCDC5 (L5, FB5) → GND connection
⑥DCDC6 (L6, FB6) → GND connection
⑦nWAKEUP→OPEN
⑧PWR_EN → 5V pull-up (do not connect with MPU)
[MPU:AM4378]
⑨RTC_WAKEUP→GND
⑩RTC_PWRONRSTn→Input the signal converted from PMIC's PGOOD to 1.8V
⑪Connect CAP_VDD_RTC→VDD_CORE
⑫Connect VDDS_RTC→1.8V
⑬RTC_PMIC_EN→OPEN (Do not connect with PMIC)
I'm especially concerned about whether ② and ⑧ are correct.
Thanks,
Conor
