Product details

Temperature grade and environment

Rated for junction temperature from -40°C to 125°C, this part covers industrial control, outdoor telecom, and some under-hood automotive environments — basically any place where the electronics see heat soak or cold starts. The wide range means you don't need a separate industrial-grade variant for a motor drive or a base-station power supply.

Package and mounting

SC-70-3 is a tiny three-lead package. It's surface-mount and reworkable with hot air if the pad layout has decent thermal relief.

Lifecycle and sourcing

ROHS3 compliant.

Frequently asked questions

Is TLV803EB46DCKR active low or active high reset?

It is active-low reset. The output goes low when the supply drops below the threshold and stays low for the reset timeout period after recovery. Because it is open-drain, you need an external pull-up resistor to the logic supply.

What is the reset timeout of TLV803EB46DCKR?

The reset timeout is 40µs typical. That is the duration the reset output stays low after the supply rises above the threshold — short enough to avoid holding the system in reset through a normal power-up sequence, but fast enough to catch brief brown-outs.

Is TLV803EB46DCKR RoHS compliant?

Yes, it is ROHS3 compliant.
