APPLICATION NOTE 231
Compensating for Sense Resistor Self Heating
Abstract: Many of Dallas Semiconductor’s battery monitors contain the option to include an internal sense
resistor to measure current. In certain applications, heat generated by the flow of current through the sense
resistor can introduce error into the on-chip temperature sensor reading performed by the battery monitor
device. This application note addresses the concern of self-heating, including the amount which can be
expected under varying circumstances and configurations. It then presents a step-by-step approach to easily
implement compensation alg……
