Dallas Semiconductor DS1233D EconoReset Datasheet
The DS1233D EconoReset monitors a 5 V supply and forces a reset when the voltage goes out of tolerance. It holds the reset active for about 350 ms after the supply returns to the acceptable range, allowing the processor and power supply to stabilize.
The device is offered in a low‑cost TO‑92 package or a surface‑mount SOT‑223 package, includes an internal 5 kΩ pull‑up resistor, and operates from –40 °C to +85 °C. Electrical characteristics such as VCC trip points (5 %, 10 %, 15 %) and low operating current (≈50 µA) are provided for system designers.
