MAX9015/MAX9016/MAX9017/MAX9018/MAX9019/MAX9020 are ultra-low power comparators from Texas Instruments, with ultra-low voltage supply range and ultra-low current consumption, which can be applied to battery monitoring and management systems.
The MAX9015–MAX9020 family comprises single and dual nanopower comparators offered in an 8‑pin SOT23 package. They feature Beyond‑the‑Rails™ inputs, operation down to 1.8 V, and ultra‑low supply currents ranging from 0.85 µA to 1.2 µA, making them suitable for 2‑cell battery monitoring and other low‑power applications.
The document provides absolute maximum ratings, detailed electrical characteristics, pin descriptions, and example circuits such as window detectors, zero‑crossing detectors, and logic‑level translators. Layout recommendations include a 0.1 µF bypass capacitor placed close to the VCC pin and minimizing trace lengths for optimal performance.
| Supply Current (typical) | 0.85 µA – 1.2 µA |
|---|---|
| Output Drive Capability | ±6 mA |
| Reference Voltage (A‑grade) | 1.236 V ±1 % |
| Operating Temperature Range | -40 °C to +85 °C |
| Package | 8‑pin SOT23 |
The input voltage range extends 200 mV beyond the supply rails.
A 0.1 µF capacitor placed as close as possible to the VCC pin is recommended.
