Note 1:
The sense trip levels are determined by an internal resistor divider network that provides a typical difference of 30mV from
SNSHI to SNSLO. Slight variation in this delta is seen if there is a resistor mismatch in the network.
Note 2:
Typical variations of Negative Delta Voltage and Thermistor Input Resolution parameters are less than ±4mV.
