AWR2944EVM: AWR2944 power management

? ??

Part Number: AWR2944EVM
Other Parts Discussed in Thread: AWR2944, LP87745

Tool/software:

e used LP87745 with AWR2944, and the current test found that the timing of the power supply is inconsistent with the 2944 specification. The current test found that the 1.8V voltage is before 1.2V, which is inconsistent with the specification. Please help confirm the impact of such use;Our design is also a reference to the development board design

Hi,

The part is in reset, until all power rails are good. So this timing should not be critical. I will check with PMIC team about this, and whether there is any timing control on the outputs of the PMIC.

Ali

Hi,

I have some feedback about any constraint regarding the power rails relative timing - this is not critical and the timing you shared is ok.

Ali
