7. Operational Description

7.1.

Over temperature protection

To prevent destruction due to temperature rise, the outputs are turned off when the junction temperature of this

product exceeds the overheat detection temperature (TSD). When the junction temperature falls below the

hysteresis set temperature (TSD-ΔTSD), the unit recovers to normal operation.

7.2.

Over current protection

When the output current exceeds the overcurrent detection value (IOC) due to a load short-circuit, etc., the output

is turned off for the overcurrent protection operation time (tOFF-DUTY). The output will then recover, but if the

overcurrent condition persists, the output will be turned off again for the overcurrent protective operation period

(tOFF-DUTY).
