DS1233Z-15

Supervisors Overview

The DS1233Z-15+ is a voltage supervisory circuit from the DS1233Z series, designed for precise power monitoring in microprocessor systems. It features a threshold voltage of 4.125 V with an accuracy of 15%, and an overvoltage threshold of 4.24 V. The device operates within a supply voltage range up to 5.5 V and draws a working current of 50 uA. It provides a reset delay time of 350 ms and supports active low, open drain, and push-pull output types. Packaged in SOT-223-4 for surface mount installation, it functions within a temperature range of -40 C to +85 C.
