XC6101~XC6105, XC6111~XC6117 series are groups of high-precision, low current consumption voltage detectors with manual reset input and watchdog functions incorporating CMOS process technology.
The XC6101‑XC6105 and XC6111‑XC6117 series are high‑precision, low‑current voltage detectors with manual reset and watchdog functions. They integrate a reference voltage source, delay circuit, comparator and output driver, providing two output types (VDFL low‑when‑detected and VDFH high‑when‑detected) without external components for delay.
The document details electrical characteristics, pin configurations for SOT‑25 and USP‑6C packages, timing charts, and marking rules. It also lists typical applications such as microprocessor reset circuits, memory battery backup, power‑on reset and power‑failure detection.
| Detect Voltage Range | 1.6 V ~ 5.0 V |
|---|---|
| Operating Voltage Range | 1.0 V ~ 6.0 V |
| Release Delay Time (typical) | 1.6 s, 400 ms, 200 ms, 100 ms, 50 ms, 25 ms, 3.13 ms |
| Watchdog Timeout Period (typical) | 1.6 s, 400 ms, 200 ms, 100 ms, 50 ms, 6.25 ms |
| Output Current (reset output) | 20 mA |
The manual reset pin is internally pulled up to the V_IN voltage level, so it can be left unconnected if unused; when driven low it asserts a reset.
Six watchdog timeout periods are available, ranging from 6.25 ms to 1.6 s.
Typical release delay times are 1.6 s, 400 ms, 200 ms, 100 ms, 50 ms, 25 ms, and 3.13 ms.
The detectors provide an N‑channel open‑drain output and a CMOS output, selectable as VDFL (low when detected) or VDFH (high when detected).
