One voltage reference exhibits a positive temperature coefficient (tempco), and the other voltage reference exhibits a negative tempco. The temperature at which both voltage references are equal determines the temperature trip point. The Functional Block Diagram shows the comparator, the NFET open-drain device connected to the OT pin, the positive tempco reference using the external RSET resistor, the negative tempco reference, and the hysteresis control. The voltage of the positive tempco reference is controlled by external resistor RSET. 7.2 Functional Block Diagram |
