6.3 Feature Description

The TMP392 requires two resistors to set the two trip points and hysteresis, according to Table 6-1 and Table 6-2 for the hot and warm channel device. The output of the TMP392 is open-drain and requires two pullup resistors. TI recommends to use a pullup voltage supply that does not exceed VDD + 0.3V. The pullup resistors used in between the OUTA and OUTB pins and the pullup supply must be greater than 1kΩ. The device powers on when the supply voltage goes beyond 1.5V, and starts sampling the input resistors to set the two trip points and hysteresis value after power-on. These values remains the same until the device goes through a power cycle. After the device sets the trip points and hysteresis level, the device updates the output every half a second. The conversion time is typically 0.65ms when the temperature is checked against the trip points and the outputs are updated. The device remains in standby mode between conversions. If either channel is not used, the output can be grounded or left floating.
