*1. −V_DET: Actual detection voltage value, −V_DET(S): Set detection voltage value
*2. Hysteresis width is "unavailable", so release voltage = detection voltage.
*3. The current flowing through the SENSE pin resistance is not included.
*4. V_DS: Drain-to-source voltage of the output transistor
*5. The time period from when the pulse voltage of −V_DET(S) + 1.0 V → −V_DET(S) − 1.0 V is applied to the SENSE pin to
when V_OUT reaches V_DD / 2, after voltage of 16.0 V is applied to the VDD pin and the SENSE pin input voltage (V_SENSE)
reaches the release voltage once.
*6. The time period from when voltage of 16.0 V is applied to the VDD pin and the pulse voltage of −V_DET(S) − 1.0 V →
−V_DET(S) + 1.0 V is applied to the SENSE pin to when V_OUT reaches V_DD / 2.
