7.1 Overview

The TMP390-Q1 ultra-low power, dual channel, resistor programmable temperature switches enable detection and protection of system thermal events over a wide temperature range. The TMP390-Q1 offers independent overtemperature (hot) and undertemperature (cold) detection. The trip temperatures and hysteresis options are programmed by two E96-series (1%) standard decade value resistors on the SETA and SETB pins. The TMP390-Q1 can enable a customer board-level manufacturing test through the trip test function that can force the SETA or SETB pins to logic high to activates the digital outputs.
