The S-808xxC series is a series of high-precision voltage detectors developed using CMOS process.
The S-808xxC series from Seiko Instruments provides ultra‑small package voltage detectors with a fixed detection voltage accuracy of ±2.0 %. Two output forms are offered – N‑channel open‑drain and CMOS (both active‑low) – and the devices consume as little as 0.8 µA to 1.3 µA depending on the detection voltage.
The detectors are intended for battery checkers, power‑failure monitoring, portable equipment power monitoring, and reset functions in micro‑computers. Various package options (SC‑82AB, SOT‑23‑5, SOT‑89‑3, SNT‑4A, TO‑92) are available to suit different form‑factor requirements.
| Detection voltage accuracy | ±2.0 % |
|---|---|
| Ultra‑low current consumption | 1.3 µA typ (≤1.4 V detection, VDD=1.5 V) / 0.8 µA typ (≥1.5 V detection, VDD=3.5 V) |
| Operating voltage range | 0.65 V‑5.0 V (≤1.4 V detection) / 0.95 V‑10.0 V (≥1.5 V detection) |
| Hysteresis | 5 % typ. |
| Detection voltage range | 0.8 V‑6.0 V (0.1 V step) |
The series offers two output forms: N‑channel open‑drain and CMOS output, both active‑low.
Current consumption is as low as 1.3 µA typical at ≤1.4 V detection (VDD = 1.5 V) and 0.8 µA typical at ≥1.5 V detection (VDD = 3.5 V).
