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 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"

⇔ Celsius Conversion equation]

°C = (°F − 32) × 5 / 9

°F = 32 + °C × 9 / 5
