MAX6804US29D3+T

Maxim Integrated · Monitors & Reset Circuits · SOT-143-4

MAX6804US29D3+T from Maxim Integrated, in a SOT-143-4. 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 Ground reference for the supervisor.
2 RESET output Active-low reset output that is asserted while VCC is below the reset threshold or while MR is asserted, and remains asserted for the reset timeout period tRP after VCC rises above the threshold or MR is deasserted; on the MAX6804 this output is push/pull.
3 MR input Manual-reset input where a logic low asserts reset and reset stays asserted while MR is low and for tRP after MR goes high; leave unconnected or connect to VCC if not used.
4 VCC power_in Supply voltage input; the MAX6804 is guaranteed to be in the correct reset state down to VCC = 0.7V and the supply range is specified up to 5.5V over 0°C to +125°C.
