AWR2243: Power Sequencing

robert hoff

Part Number: AWR2243

Hello,

Does the AWR2243 have specific power sequencing requirements other than bringing up the power rails before reset is released? The datasheet shows the rails coming up sequentially, but no timing spec is given in regards to this.

Thanks,

Robert

Hello Robert,

All supplies come from the PMIC without any intervention from the device, so no specific sequence is required as such. As you already said, you just need to ensure all supplies are stable before NRST is deasserted.
