Housed in a SOT-23-5 package (also listed as SOT-753), this is a surface-mount part. The open-drain output requires an external pull-up resistor.
Pricing and availability are confirmed at quote time against an RFQ — no stock-count or price figures are published here, but a request for quote will return current market terms.
The reset timeout is a minimum of 140ms. This means the reset output stays asserted for at least 140ms after the monitored voltage rises above the threshold, giving the system power supply time to stabilise before the processor starts executing code.
The MAX6446UK46L+T is available in a SOT-23-5 surface-mount package, also described as SC-74A or SOT-753. The supplier device package is SOT-23-5.
It monitors a single voltage rail with a threshold of 4.625V. When the monitored voltage falls below this level, the reset output goes active low to hold the processor in reset.
