Abstract:
Current sensing with RDS ON  correction is disclosed. In an embodiment, a method comprises: measuring an approximate temperature of a MOS transistor switch by a temperature sensor to yield a measured temperature; calculating a corrected temperature from the measured temperature using a stored temperature sensor gain and offset correction function; measuring a gate drive voltage for the MOS transistor; calculating a voltage correction factor using a stored voltage correction function, wherein the stored voltage correction function is a function of the corrected temperature and the gate drive voltage; measuring a RDS ON  voltage drop across the MOS transistor switch to yield a measured RDS ON  voltage drop; and calculating the current using the measured RDS ON  drop and the voltage correction factor.

Claim (Index 10):
The current sensor of  claim 8 , wherein the processing device is configured to calculate the corrected temperature from the measured temperature signal by multiplying the measured temperature signal by a temperature gain factor to yield a product and adding a temperature offset factor to the product to yield the corrected temperature, wherein the temperature gain factor is determined using the stored temperature sensor gain and offset correction function and the measured temperature.
