TIDEP-0092: Power Sequencing between AWR1642 & LP8752

Part Number:TIDEP-0092

Hi,

Per the TIDEP-0092, the AWR1642 receives all the 4 rails from PMIC (LP8752). But since PMIC is enabled by the the AWR1642 via I2C and enable signals from AWR1642, this implies AWR1642 has to be powered first before it can activate PMIC, which would not be possible since all the 4 rails going to AWR1642 originate from PMIC. Is this accurate?

Kindly clarify the power sequencing between PMIC and AWR1642. Specifically, which device come on first and on which rail?

Thanks,

John
