Description of Protector Circuit

(1)

Overtemperature Protection

• The overheating detector circuits feature hysteresis. After overheating is detected, normal operation

is restored only when the junction temperature falls by the hysteresis amount (10°C typ.) in relation

to the overheating detection temperature.

(2)

Overcurrent Protection

• When overcurrent is detected, the overcurrent limiter function limits the output current. Normal

operation is restored when the load current drops below the overcurrent detection value.
