MAX917/MAX918/MAX919/MAX920 series nanopower comparators feature ultra-low supply current (only 380nA), guaranteed to operate down to +1.8V, and are ideal for all 2-cell battery applications, including monitoring/management, ultra-low-power systems, mobile communications, notebooks and PDAs, threshold detectors/discriminators, sensing at ground or supply line, telemetry and remote systems, medical instruments, etc.
The MAX917‑MAX920 family are nanopower comparators offered in a space‑saving 5‑pin SOT23 package. They feature Beyond‑the‑Rails inputs, operate down to +1.8 V, and are available with an on‑board 1.245 V reference (MAX917/MAX918) or without reference (MAX919/MAX920). Applications include 2‑cell battery monitoring, ultra‑low‑power systems, mobile communications, notebooks, PDAs, and medical instruments.
