The 140 ms minimum timeout covers the startup time of most quartz oscillators and PLL-based clocks. The threshold voltage is set internally to 3.08 V, which suits 3.3 V logic systems. The part monitors a single voltage rail; for multi-rail supervision, multiple MAX803 devices or a multi-channel supervisor is needed. ## SC-70-3 package and surface-mount assembly Housed in a 3-lead SC-70 (SOT-323) package, the MAX803TEXR+T occupies minimal board area. Surface-mount mounting is specified, and the package is compatible with reflow soldering profiles typical for lead-free assemblies.","metaTitle":"MAX803TEXR+T Simple Reset/Power-On Reset, 3.08V Threshold","metaDescription":"Analog Devices MAX803TEXR+T supervisor IC, active-low open-drain reset, 140ms timeout, -40°C to +125°C, SC-70-3.
