 Explanation of Terms
1. Detection voltage (−V_DET)
The detection voltage is a voltage at which the output in Figure 21 or Figure 22 turns to "L" (VDD detection
product: V_DD, SENSE detection product: V_SENSE). 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 17, Figure 19).
Example: In −V_DET = 5.0 V product, the detection voltage is either one in the range of 4.925 V ≤ −V_DET ≤ 5.075 V.
This means that some −V_DET = 5.0 V product have −V_DET = 4.925 V and some have −V_DET = 5.075 V.
2. Release voltage (+V_DET)
The release voltage is a voltage at which the output in Figure 21 or Figure 22 turns to "H" (VDD detection product:
V_DD, SENSE detection product: V_SENSE).
The difference of detection voltage and release voltage is 5.0% typ.
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 18, Figure 20). The range is calculated from the actual detection voltage (−V_DET) of a product.
In the S-1011 Series C / G / L / Q type, the release voltage (+V_DET) is the same value as the actual detection
voltage (−V_DET) of a product.
Example: In −V_DET = 6.0 V product, the release voltage is either one in the range of 6.0873 V ≤ +V_DET ≤ 6.5772 V.
This means that some −V_DET = 6.0 V product have +V_DET = 6.0873 V and some have +V_DET = 6.5772 V.
