*1. Since products are not screened at high and low temperatures, the specification for this temperature range is
guaranteed by design, not tested in production.
*2. Even if overcurrent 1 detection voltage and overcurrent 2 detection voltage are in the same range, V_DIOV1 is lower than
V_DIOV2.
*3. It indicates that DO pin output logic is determined.
