This IC is a temperature switch IC that changes the IC output level from Low to High when the temperature
around the IC reaches the detection temperature. With the hysteresis function, IC output level returns to
Low when the ambient temperature drops to the hysteresis temperature selected after detection. Detection
temperature T
DET
can be selected in 1.0°C steps between the range of 60 to 90°C with rank expansion, with
detection temperature accuracy of ±2.0°C.
