The device is part of a family of ultra-low power, dual channel, resistor programmable temperature switches that enable protection and detection of system thermal events from . The . The trip temperatures (T TRIP ) and thermal hysteresis (T HYST ) options are programmed by two E96-series resistors (1% tolerance) on the SETA and SETB pins. Channel A resistors can range from 1.05 KΩ to 909 KΩ, representing one of 48 unique values. Channel B resistors can range from 10.5 KΩ to 909 KΩ

The value of the resistor to ground on SETA input sets the T TRIP threshold of Channel A. The value of the resistor to ground on SETB input sets the T TRIP threshold of Channel B, as well as the T HYST options of 5°C, or 10°C for both channels, to prevent undesired digital output switching. When the SETB input is connected to ground, Channel A operates with 20°C hysteresis. Resistors accuracy has no impact to T TRIP accuracy.

To enable customer board-level manufacturing, the supports a trip test function where the digital outputs are activated by exercising the SETA or SETB pin.
