The MAX917-MAX920 series of nanopower comparators feature ultra-low supply current, making them ideal for 2-cell battery monitoring/management applications.
The MAX917–MAX920 family are nanopower comparators offered in a space‑saving SOT23 package. They provide Beyond‑the‑Rails™ inputs and operate down to +1.8 V, with optional on‑board 1.245 V reference for the MAX917/918 variants. The devices draw ultra‑low supply currents of 750 nA (with reference) or 380 nA (without reference) and support rail‑to‑rail output swings up to ±8 mA.
Typical applications include 2‑cell battery monitoring, ultra‑low‑power systems, and logic‑level translation. The datasheet includes detailed electrical characteristics, pin configurations, application circuits, and package information for designers.
