APPLICATION NOTE 3889
Using the DS2746 to Identify a Battery-Pack Based on an
Identification Resistor

Abstract: The DS2746 has two auxiliary inputs to allow voltage sampling of resistor divider circuits; these
inputs are ideal for measuring thermistor or battery-pack identification resistors. This application note
describes how to calculate the resistance (in ohms) of the unknown resistor in order to properly identify a
battery pack based on an identification resistor.


Calculating Unknown Resistance

The VOUT pin drives a resistive divider formed by a known resistor and an unknown resistance that is to be
measured. The device repor……
