*1.

The minimum operation voltages are as follows under the operation ambient temperature over

+100°C.

+55°C to +100°C)

+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.

°C = (°F − 32) × 5 / 9

°F = 32 + °C × 9 / 5
