Description

The MAX9018BEKA is a linear comparator model in the electronic component category. It is a nanopower comparator with Beyond-the-Rails™ inputs, designed to operate down to 1.8V. It is available as a single MAX9015/MAX9016 or dual MAX9017–MAX9020 version. The A-grade packages feature an on-board 1.236V ±1% reference, while the B-grade packages feature a 1.24V ±1.75% reference. With an ultra-low supply current of 0.85µA (MAX9019/MAX9020), 1µA (MAX9015/MAX9016), or 1.2µA (MAX9017/MAX9018), it is well-suited for 2-cell battery monitoring/management applications.
