2.63V threshold, 140 ms timeout — the supervisory baseline
The MAX6713REXS+T is a single-channel voltage supervisor from Analog Devices, monitoring a single rail at 2.63V and asserting a reset signal when the supply drops below that threshold. The reset output stays active for a minimum of 140 ms after the rail recovers, giving the downstream processor time to stabilize its clock and power rails before release. This output structure allows the supervisor to interface with multiple supply domains without level-shifting, as long as the pull-up voltage stays within the absolute maximum rating of the pin.
SC-70-4 footprint and temperature grade
Housed in a 4-lead SC-70-4 (SC-82A, SOT-343) package, the MAX6713REXS+T occupies minimal board area — roughly 2.0 mm × 2.1 mm — and suits dense mixed-signal designs where a dedicated supervisor IC is preferred over an internal brown-out detector. The operating temperature range spans -40°C to +125°C (TA), covering industrial and automotive ambient conditions. At the high end, the threshold accuracy and timeout period remain within datasheet limits — no derating needed for the supervisor itself, though the pull-up resistor's temperature coefficient should be considered for precise timing.
