What the 2.63V threshold and 140ms timeout mean for your rail
The MAX706PCPA+ is a single-voltage Power Supply Monitor from Analog Devices, watching a 2.63V threshold — that's a 3.3V rail under brownout, since the monitor triggers before the logic supply drops out of spec. The 140ms minimum reset timeout holds the microprocessor in reset long enough for the supply to settle after a fault clears — a 100ms glitch on the 3.3V bus won't cause a partial boot. Both Active High and Active Low reset outputs are available from the same device, so it drives either the reset pin of a microcontroller or the enable input of a downstream regulator without an inverter.
Package and temperature grade for the board
Housed in an 8-DIP (0.300", 7.62mm) through-hole package (supplier device package 8-PDIP), it plugs into a standard 0.100-inch pitch socket or solders directly into the PCB — no special footprint beyond the 0.300-inch row spacing.
