Product details

Package and environment

Housed in a SOT-23-5 package (also listed as SOT-753), this is a surface-mount part. The -40°C to 85°C operating temperature range covers industrial environments. The open-drain output requires an external pull-up resistor.

Lifecycle and sourcing

The MAX6446UK46L+T carries an Active lifecycle status and is ROHS3 compliant. 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.

Frequently asked questions

What is the reset timeout for MAX6446UK46L+T?

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.

What package is MAX6446UK46L+T available in?

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.

What does MAX6446UK46L+T monitor?

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.
