Ratiometric temperature sensing

Other Parts Discussed in Thread: BQ76PL536-Q1

Hi,

I am using your bq76PL36 chip, and am trying to understand the connection between the overtemperature trip setpoints and temperature. In "Table1: Overtemperature Trip Setpoints" of the bq76PL536-Q1 datasheet, there are two columns labeled "Vts Ratio Set" and Vts Ratio Clear." I understand that Vts is the ratio of thermistor voltage to REG50 voltage, but what is the difference between "SET" and "CLEAR" Vts ratios?  Thanks!

    it shows the hysteresis in the Overtemp set points (set = set the flag, clear=clear the flag)

    For example, CONFIG_OT=1, an Overtemp flag is set when the voltage on the TS pin rises above 1V and the Overtemp flag is cleared when the voltage on the TS pin drops below 0.883V.
