*1. The minimum operation voltages are as follows under the operation ambient temperature over +100°C.
VDD = 2.3 V min. (Detection temperature = +55°C to +100°C)
VDD = 2.7 V min. (Detection temperature = +40°C to +54°C)
*2. The hysteresis temperature can be switched in 0°C, 2°C, 4°C, 10°C, and is set by the HYS1 pin and HYS2 pin.
