1.58V threshold, 140 ms timeout — what it means for the BOM
The MAX6821VUK+T: The 140 ms minimum reset timeout ensures the downstream processor stays in reset long enough for the supply to stabilise after power-up — common for microcontrollers and SoCs that need a clean start before the bootloader runs.
Housed in a SOT-23-5 (SC-74A) surface-mount package, the part fits a standard 5-pin footprint with 0.95 mm pitch — no exotic pad geometry required.
