Application Circuit
If the desired detection voltage range is other than those provided by the S-1701 Series, the detection voltage can be
changed by using a divided resistor or diode in the SENSE pin products (N/P/Q/R/S/T types) as shown in Figures 38 and
39.
In the case shown in Figure 38, the hysteresis width also changes at the same time.

Caution If Ra and Rb are larger, the hysteresis may be greater than the result of the above formula due to the
through current of the IC.
