*1. In the S-5841 with SOT-23-5 package, 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 = high level,
10°C of hysteresis temperature during HYS1 = low level
Hysteresis option B : 4°C of hysteresis temperature during HYS1 = high level,
10°C of hysteresis temperature during HYS1 = low level
