MAX811RDB4RG

HANSCHIP semiconductor · Supervisor And Reset ICs · SOT-143

MAX811RDB4RG from HANSCHIP semiconductor, in a SOT-143. 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 GND power_in Negative supply terminal (ground) of the device; the datasheet gives no further electrical limits for this pin.
2 VRESET output Reset output that goes low when VCC is below the threshold Vth or when the enable input MR is low, and goes high after Trp (500 ms typical) once VCC rises above Vth or MR returns high; VOL is at most 0.5 V at 3.2 mA sink and VOH is at least 0.8 VCC at 500 µA source.
3 MR input Active-low enable control input; VIH is at least 0.7 VCC and VIL is at most 0.2 VCC, and the enable low pulse must be at least 10 µs (tMR).
4 VCC power_in Positive supply input with an operating range of 1.0 V to 6.0 V and an absolute maximum of 6.5 V.
