*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 set by the HYS1 pin.
These two types are selectable by option.
Hysteresis option A: 2°C of hysteresis temperature during HYS1 = "H",
10°C of hysteresis temperature during HYS1 = "L"
Hysteresis option B: 4°C of hysteresis temperature during HYS1 = "H",
10°C of hysteresis temperature during HYS1 = "L"
[Fahrenheit â Celsius Conversion equation]
°C = (°F â 32) à 5 / 9
°F = 32 + °C à 9 / 5
