*1. −VDETn: Actual detection voltage value, −VDETn(S): Set detection voltage
*2. VHYSn: Actual hysteresis width, −VHYSn(S): Set hysteresis width
*3. −VDETtotal: Total detection voltage
−VDETtotal = −VDET1(S) + −VDET2(S) + −VDET3(S)
*4. The Change in temperature of the detection voltage [mV/°C] is calculated by using the following equation.
Δ − VDETn

*1. Change in temperature of the detection voltage
*2. Set detection voltage
*3. Detection voltage temperature coefficient
*5. Since products are not screened at high and low temperature, the specification for this temperature range is
guaranteed by design, not tested in production.
