The XC61H series is a highly accurate, low power consumption CMOS voltage detector with a delay circuit. Detect voltage is accurate with minimal temperature drift. Output configurations are available in both CMOS and N-channel open drain. Since the full delay circuit is built-in, an external delay-time capacitor is not necessary so that high density mounting is possible.
The XC61H Series is a highly accurate, low‑power CMOS voltage detector that includes an internal delay circuit, eliminating the need for an external delay capacitor. It is intended for use in microprocessor reset circuits, battery‑monitoring, power‑on‑reset, and power‑failure detection applications.
Key features include selectable CMOS or N‑channel open‑drain output, a built‑in release delay from 1 ms to 50 ms, and a compact SOT‑23 package. The datasheet details electrical characteristics, pin assignments, typical application circuits, and recommended usage guidelines. This manual is written in Chinese.
