Some applications require that multiple DS1859 devices — dual, temperature-controlled resistors with internally calibrated monitors — be connected on the same I2C address bus. This application note shows how to change the I2C slave address on one of the DS1859 devices when two are connected together on the same I2C bus. The process described can be extended and applied to any additional DS1859 devices added to that bus. The note also discusses how to access the device’s auxiliary slave address.
