Using the DS2746 to Identify a Battery-Pack Based on an Identification Resistor
The DS2746 two-wire battery monitor 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.
