4.125V threshold supervisor for 5V rails
The DS1233D-15+: This trip point is designed for a nominal 5V supply — it holds the reset output asserted until the rail rises above the threshold and the 250ms minimum timeout elapses, ensuring the downstream processor or logic starts from a known state. An external pull-up resistor to the logic supply rail is required; the open-drain topology allows the output to be wire-ORed with other reset sources in the system. The through-hole TO-92-3 package (TO-226-3, TO-226AA) is a low-cost, hand-solderable form factor for single-board designs or retrofit into existing through-hole footprints.
Active production — ROHS3 compliance
The part is ROHS3 Compliant, confirming it meets the EU Restriction of Hazardous Substances directive for lead, mercury, cadmium, and other restricted substances — a requirement for shipping into European markets and many global OEM supply chains.
