MAX706ASESA+T

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

MAX706ASESA+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 resets the device when pulled below 0.6V, is TTL/CMOS compatible when VCC = 5V, is internally pulled up by a 70µA source, and should be connected to VCC or left unconnected if unused.
2 VCC power_in Supply voltage input; the Electrical Characteristics give a supply range of 1.2V to 5.5V for the E (-40°C to +85°C) grade, and the AS-suffix conditions are stated as VCC = 3.0V to 5.5V.
3 GND power_in Ground reference for the device.
4 PFI input Adjustable power-fail comparator input that is compared to an internal 1.25V threshold, where PFO goes low when PFI falls below 1.25V, and which should be connected to GND if not used.
5 PFO output Active-low power-fail comparator output that asserts (sinks current) when PFI is below the internal 1.25V threshold and should be left unconnected if not used.
6 WDI input Watchdog input where a falling or rising transition must occur within 1.6s to prevent WDO from asserting; on the AR/AS/AT versions the watchdog disables when WDI is left open or driven by a tri-state output in high impedance with leakage below 600nA.
7 RESET output Active-low reset output that remains low while VCC is below the reset threshold or MR is held low, and for 200ms after the reset conditions end.
8 WDO output Active-low watchdog output that goes low when WDI has no transition within 1.6s, also goes low when VCC falls below the reset threshold, and returns high as soon as VCC rises above the reset threshold.
