Describe the problem you have/What new integration you would like

I request ESPHOME team to implement support for DS2438 1-Wire Battery Management Smart Battery Monitor with Temp Sensor.

Please describe your use case for this integration and alternatives you've tried:

The DS2438 is a Smart Battery Monitor and is used in its original function as a mobile phone battery monitor. For automation, especially in the smart home area, it is also used for other functions:

as voltage meter (supplies the bus voltage (VDD)
as thermometer - the temperature is measured
AD-Converter (VAD) - is used to measure humidity or brightness
Current input (XSENS) - freely available

Additional context

Type/designation | DS2438Z+ Housing | SOIC-8 (SMD) Supply voltage | 2.4 V to 10 V Function | Temperature sensor Analog Input 0-10VDC (VAD) Analog Input 0-250mV, +/- (Xsens) Measurement Operating voltage (VDD) Operating temperature | -40°C to +85°C Details | See data sheet DS2438.pdf DS2438 current.pdf grafik

Thank you very much for your great work!!!!!

I would like to announce also my interest in this feature. Would be great, if it would be easily supported :-)

This is great as many analog sensors (temp, hum, light,...) can be connected easily to 1w bus. There is already a product https://sedtronic.eu/en/unica-1wire/30-52-unica-1-wire-tvsl.html heavily used in Loxone home automation systems.
