MAX9611/9612 High Side Current+Voltage+Temperature Sensor

The MAX9611 sensor platform allows you to use your MAX9611/MAX9612 (datasheet) 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 I²C, and is meant to act as a high-side current sense amplifier.

The I²C is required to be set up in your configuration for this sensor to work.
