1-Wire Battery Management Smart Battery Monitor with Temp Sensor
|Supply voltage||2.4 V to 10 V|
|Operating temperature||-40°C to +85°C|
|Details||See data sheet|
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
We recommend to connect a 0.1µF capacitor (ceramic) in parallel to the 1-Wire device, i.e. from 5V to GND. The capacitor should be placed as close as possible. This increases the stability of the entire 1-Wire network.
