 Explanation of Terms
1. Detection voltage (−V_DET)
The detection voltage is a voltage at which the output in Figure 16 or Figure 17 turns to "L". The detection voltage
varies slightly among products of the same specification. The variation of detection voltage between the specified
minimum (−V_DET min.) and the maximum (−V_DET max.) is called the detection voltage range (Refer to Figure 14).
Example: In the S-19103C18, the detection voltage is either one in the range of 1.733 V ≤ −V_DET ≤ 1.867 V.
This means that some S-19103C18 have −V_DET = 1.733 V and some have −V_DET = 1.867 V.
2. Release voltage (+V_DET)
The release voltage is a voltage at which the output in Figure 16 or Figure 17 turns to "H". The release voltage
varies slightly among products of the same specification. The variation of release voltage between the specified
minimum (+V_DET min.) and the maximum (+V_DET max.) is called the release voltage range (Refer to Figure 15). The
release voltage (+V_DET) is the same value as the actual detection voltage (−V_DET) of a product.
Example: For the S-19103C18, the release voltage is either one in the range of 1.733 V ≤ +V_DET ≤ 1.867 V.
This means that some S-19103C18 have +V_DET = 1.733 V and some have +V_DET = 1.867 V.
