The MAX9117-MAX9120 nanopower comparators in space-saving SC70 packages feature Beyond-the-Rails™ inputs and are guaranteed to operate down to +1.6V. The MAX9117/MAX9118 feature an on-board 1.252V ±1.75% reference and draw an ultra-low supply current of only 600nA, while the MAX9119/MAX9120 (without reference) require just 350nA of supply current. These features make the MAX9117-MAX9120 family of comparators ideal for all 2-cell battery-monitoring/management applications. The unique design of the output stage limits supply-current surges while switching, virtually eliminating the supply glitches typical of many other comparators. This design also minimizes overall power consumption under dynamic conditions. The MAX9117/MAX9119 have a push-pull output stage that sinks and sources current. Large internal-output drivers allow rail-to-rail output swing with loads up to 5mA. The MAX9118/MAX9120 have an open-drain output stage that makes them suitable for mixed-voltage system design. All devices are available in the ultra-small 5-pin SC70 package.
The MAX9117‑MAX9120 family are nanopower comparators offered in a 5‑pin SC70 package. They operate down to +1.6 V and feature ultra‑low supply currents (600 nA for reference versions, 350 nA for non‑reference versions) with rail‑to‑rail output swing up to ±5 mA.
These devices include an internal 1.252 V ±1.75 % reference (MAX9117/MAX9118) or an open‑drain output option (MAX9118/MAX9120) for flexible system designs. They are targeted at 2‑cell battery‑monitoring, ultra‑low‑power, and mobile applications, and are specified for –40 °C to +85 °C operation.
