Supervisor for a single supply rail
The MAX6856UK23D3: The push-pull, totem-pole output drives the reset signal without needing an external pull-up resistor — it sources and sinks current directly, which simplifies the connection to the downstream processor's reset input. The 150ms minimum reset timeout holds the processor in reset long enough for the supply rail to stabilise after power-up or a brown-out event, preventing the core from starting execution on an unsteady rail.
Package and temperature grade
Housed in the SOT-23-5 package (SC-74A, SOT-753), this surface-mount supervisor fits into compact PCB layouts where board area is tight.
Sourcing and compliance reality
Note the RoHS non-compliant flag on this part number — if your BOM requires RoHS-10 or REACH conformance, verify the exemption or source the lead-free suffix variant.
