No hidden pads, no centre pad — the board layout is straightforward. ## Active production, legacy RoHS status Note the RoHS status is non-compliant — this part carries a tin-lead (SnPb) finish, not pure tin. That is typical for legacy industrial parts and means it is exempt from RoHS restrictions for certain applications, but a RoHS-compliant BOM will need an alternative or an exemption letter.","metaTitle":"MAX791ESE Power Supply Monitor, Active Low Reset","metaDescription":"Analog Devices MAX791ESE Power Supply Monitor, active low reset, 4.65V threshold, 140ms timeout, 16-SOIC.
