The active high, push-pull output drives the reset input of the processor directly — no external pull-up resistor needed. This output structure also eliminates the bus contention risk that open-drain outputs can create when multiple supervisors share a line. ## Package and temperature grade Housed in a SOT-143-4 package, the MAX812MEUS+T occupies a compact footprint on the PCB — the four-pin layout with a single ground, reset, VCC, and GND pin simplifies routing for a 2-layer board. ## Compliance and sourcing ROHS3 compliant, the part ships on tape and reel for automated assembly.","metaTitle":"MAX812MEUS+T Analog Devices Supervisor IC, 4.38V Threshold","metaDescription":"Active MAX812MEUS+T supervisor IC from Analog Devices.
