This data sheet describes the features of the ADM6305/ADM6306 multi-input programmable supervisory ICs, including adjustable input threshold voltage options, pre-trimmed VCC threshold options, manual reset input, 4 factory programmed reset timeout delays, reset output stage, low power consumption, power supply glitch immunity, 5-lead SOT-23 package, and temperature range
The ADM6305 and ADM6306 are dual‑voltage supervisory ICs designed to monitor two supply rails and provide an active‑low reset signal to microprocessor‑based systems. Their low quiescent current and small SOT‑23 package make them suitable for portable and battery‑operated equipment.
The document provides electrical specifications, pin‑out tables, functional block diagrams, theory of operation, and ordering information. Key parameters such as operating voltage range, reset timeout options, and temperature limits are listed, along with typical performance curves and layout dimensions.
| Operating voltage range (VCC) | 0.9 V to 5.5 V |
|---|---|
| Input current | 5 pA min, 16 pA typical |
| Operating temperature range | ‑40 °C to +125 °C |
| Package | 5‑lead SOT‑23 (RJ‑5) |
The reset output is an active‑low, open‑drain signal that remains valid as long as VCC exceeds 0.9 V.
Four factory‑programmed reset timeout delays are provided: 1 ms, 20 ms, 140 ms, and 1.12 s.
Both devices are supplied in a 5‑lead SOT‑23 (RJ‑5) package.
