MAX6315US31D3+T

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

MAX6315US31D3+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 pin for the device.
2 RESET output Active-low open-drain output that must be connected to an external pullup resistor; it can be pulled up to a voltage higher than VCC but less than 6V.
3 MR input Manual reset input where a logic-low asserts reset and keeps it asserted while low and for the reset timeout period after release; connect to VCC if not used.
4 VCC power_in Supply voltage input that is also the reset threshold monitor; the operating voltage range is 1.0V to 5.5V.
