The ``MAX9611`` sensor platform allows you to use your MAX9611/MAX9612
(`datasheet <https://datasheets.maximintegrated.com/en/ds/MAX9611-MAX9612.pdf>`__)
High-side current, voltage and temperature sensors with ESPHome.
This sensor supports up to +60V DC common mode voltage, has a 1.8V to 3.3V logic range,
a 12-Bit integrated ADC with :ref:`I²C <i2c>`, and is meant to act as a high-side current sense amplifier.
The :ref:`I²C <i2c>` is
required to be set up in your configuration for this sensor to work.
