Not qualified for automotive under-hood (that would require AEC-Q100, which this does not carry).
Maxim lists the DS1811-5+ as Active. Through-hole TO-92 parts tend to have longer production tails than their SMD equivalents, but the EconoReset series has been around for years — verify date codes if your QA requires fresh manufacture.
The DS1811-5+ has an active-low, open-drain output. It pulls low when VCC drops below the 4.62V threshold and releases after the 100ms timeout. Because it is open-drain, you can connect multiple reset outputs to a single pull-up resistor (wire-OR configuration).
Yes, the DS1811-5+ is ROHS3 compliant (fully lead-free, no exemptions). The '+' suffix on the order code indicates RoHS compliance in Maxim's part numbering.
