LTC2943 is getting hot up to 46°C during Battery charging

I am using a 0.100-ohm Sense resistor to sense a 7.4V Li-ion battery. where sense-  is connected to Li-ion Battery polarity positive and sense + is connected to an LTC4120  wireless charger. The problem is during charging LTC2943 temperature is getting high up to 46°C. I don't know what is the reason?

Note: Pin SDA, SCL, ALCC are currently pulled up with 2.2K.  The I2C bus is not programmed.
