The push-pull output drives the reset line directly, no external pull-up needed. This is the part you drop onto a 1.8V or 1.5V core supply to sequence an MCU, FPGA, or SoC cleanly at power-up. ## 1.575V threshold — what it covers The 1.575V threshold sits between the 1.5V and 1.8V nominal supply rails common in low-voltage digital cores. If your monitored rail dips below that level — brownout, sag, or slow ramp — the reset asserts active low and stays asserted through the 150ms timeout after recovery. That timeout gives the supply and oscillator time to stabilise before the processor starts executing code. ## Package and temperature range Housed in a SOT-23-5 surface-mount package, it operates from -40°C to 85°C. ## Sourcing and lifecycle ROHS3 compliant. No direct pin-compatible second source is listed in the official cross-reference, but the SOT-23-5 supervisor market is dense — if you need a dual-source option, we can qualify a same-function sibling against your threshold and timeout requirements.","metaTitle":"MAX6866UK16D3S+T Simple Reset/Power-On Reset","metaDescription":"MAX6866UK16D3S+T active-low push-pull reset supervisor, 150ms timeout, -40°C to 85°C.
