MAX811R

MSKSEMI · Supervisor and Reset ICs · SOT-143

MAX811R from MSKSEMI, in a SOT-143. 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 GND power_in Ground / power negative terminal. Connect to system ground.
2 RESET output Active-low reset output (open when VCC>Vth after Trp delay, low when VCC<Vth=2.63V or MR is low). VOL ≤ 0.5V at ISINK=3.2mA; VOH ≥ 0.8×VCC at ISOURCE=500µA.
3 MR input Active-low manual reset / enable control input. Pulling MR low forces RESET low; must be held low for at least tMR=10µs minimum pulse width. Logic thresholds: VMRH ≥ 0.7×VCC, VMRL ≤ 0.2×VCC.
4 VCC power_in Positive supply input, 1.0V to 6.0V operating range (6.5V absolute max). Monitored against Vth=2.63V (±2.5%) for the MAX811R variant. Quiescent current ICCH typ. 1µA (5µA max) with MR=VCC.
