Hello!

Datasheet suggests the tPOR_H (Power-On Reset Wait Time) is 500 us but we're seeing 50 to 75 ms. Is this expected?

Any other settings you're curious for? Thanks!

Hi Cameron,

This spec means the wait time from UVLO disactive to device NORMAL, it should be lower than 500usec, Can you share us the waveform for the wait time that your captured?

BRs,

Leon
