The ADM12914 is a four‑channel UV/OV positive/negative voltage monitor IC with ±0.8 % threshold accuracy and a 1 V buffered reference.
The ADM12914 is a four‑channel voltage‑monitoring IC designed to detect under‑voltage (UV) and over‑voltage (OV) conditions on both positive and negative supply rails. It offers high‑precision thresholds (±0.8 %), a 1 V buffered reference output, open‑drain UV/OV reset outputs, and an adjustable reset timeout.
Typical applications include server power monitoring, FPGA/DSP core and I/O voltage supervision, telecom equipment, and medical devices. The device is supplied in a 16‑pin QSOP package and operates from –40 °C to +125 °C. This manual is written in Chinese.
