MAX706PCSA

MSKSEMI · Supervisor and Reset ICs · SOP-8

MAX706PCSA from MSKSEMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 !MR input Manual reset input, active-low. Internally pulled up to VCC through a nominal 20 kΩ resistor (10-40 kΩ). Pulling this pin low for at least tMR (150 ns @ VCC≥4.5V, 500 ns for P/R/S/T at low VCC) asserts the reset outputs.
2 VCC power_in Supply voltage input. Operating range 3.0V-5.5V for the P version (706P/R). Reset threshold is 2.63V (typ) with 40 mV hysteresis; ICC ≈ 75 µA typ (140 µA max).
3 GND power_in Ground reference for supply and all I/O.
4 PFI input Power-fail comparator inverting input. Referenced to the internal 1.25V bandgap (1.20V-1.30V). Input current ±25 nA max. Used with an external divider to monitor a battery or secondary rail; drives !PFO low when PFI falls below 1.25V.
5 !PFO output Power-fail comparator output, active-low push-pull. VOH ≥ VCC−1.5V @ 800 µA source; VOL ≤ 0.4V @ 1.2 mA sink (4.5V<VCC<5.5V).
6 WDI input Watchdog input. Must be toggled within tWD (1.6 s typ, 2.25 s max) or a reset is generated. Leave floating (high-Z) to disable the watchdog. Minimum pulse width tWP = 50 ns @ VCC≥4.5V; input current ±150 µA max.
7 RESET output Active-HIGH reset output (706P version outputs RESET, not !RESET). Asserted while VCC is below the 2.63V threshold and held high for tRS = 200 ms (typ) after VCC rises above threshold, or while !MR is low, or when a watchdog timeout occurs. Push-pull: VOH ≥ VCC−1.5V @ 800 µA source; VOL ≤ 0.4V @ 3.2 mA sink.
8 !WDO output Watchdog output, active-low. Pulses low when the watchdog timer expires (WDI not toggled within tWD). VOH ≥ VCC−1.5V @ 800 µA source; VOL ≤ 0.4V @ 1.2 mA sink (4.5V<VCC<5.5V).
