MAX706ESA+T

Analog Devices Inc Maxim Integrated · Supervisor And Reset ICs · SOIC-8

MAX706ESA+T from Analog Devices Inc Maxim Integrated, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 MR input Active-low manual-reset input that triggers a reset pulse when pulled below 0.8V, with an internal 250µA pullup, and is TTL/CMOS compatible.
2 VCC power_in +5V supply input; the datasheet's absolute maximum rating for VCC is -0.3V to 6.0V with respect to GND.
3 GND power_in 0V ground reference for all signals.
4 PFI input Power-fail voltage-monitor input whose threshold is 1.25V; PFO goes low when PFI is below 1.25V, and PFI should be connected to GND or VCC when not used.
5 PFO output Power-fail output that goes low and sinks current when PFI is below 1.25V, and otherwise stays high.
6 WDI input Watchdog input: if WDI remains high or low for 1.6s the watchdog timer times out and WDO goes low, while floating or three-stating WDI disables the watchdog; pulses as short as 50ns can be detected.
7 RESET output Active-low reset output that pulses low for 200ms when triggered and stays low whenever VCC is below the reset threshold (4.40V for the MAX706), remaining low for 200ms after VCC rises above the threshold or MR goes high.
8 WDO output Watchdog output that pulls low when the watchdog timer completes its 1.6s count and stays low until the watchdog is cleared, and also goes low during low-line conditions when VCC is below the reset threshold.
