The 140ms minimum reset timeout holds the system in reset long enough for the supply to stabilise after a brownout or power-up, which is the window a microcontroller's oscillator and PLL need to lock before the first instruction fetch. The supplier device package is listed as 16-SOIC, meaning the same mechanical outline serves both the PCB layout and the tape-and-reel or tube handling in production. ROHS3 compliant, which covers the full ten restricted substances including the four phthalates — no exemption paperwork needed for EU or California market shipments.","metaTitle":"MAX691AESE+ Analog Devices Battery Backup Circuit","metaDescription":"MAX691AESE+ supervisor IC from Analog Devices, active high/low reset, 140ms timeout, -40°C to 85°C, ROHS3 compliant.
