Hi,

There is no specific power-on sequence for the two supplies, 3.3V and 1.2V in HX3. However, the RESETN pin should be held low until both these supplies become stable.The minimum delay for RESETN pin is recommended as 5 ms.

Please also refer to the KBA- HX3 FAQs - KBA224063

Best Regards,
Sananya
