AWRL6432: Power-on sequence

jiang ting

Part Number: AWRL6432

HI,

Could you please inform me if there are strict requirements for the power-up voltage sequencing of AWRL6432? The power supply manufacturer I am consulting with requires matching its power-up sequence. I have only seen a diagram illustrating the power-up sequence in the specification sheet; if possible, please mark the detailed information on the diagram.

Hi Jiang,
I apologize for the delayed response. Please refer to the e2e thread below, AWR1843: AWR1843 power supply sequence - Sensors forum - Sensors - TI E2E support forums. All power rails and SOP signals must be stable (and power rails at their respective high state) before NRST is released. As long as this requirement is met any voltage sequencing is fine.
