The circuit logic is such that, when any of the four detectors detects overheating, the circuit turns off the output of both its channels(for example, both channels 1 and 2). z 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 z 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.

As protection against reverse connection of batteries is not provided, take protective measures using external circuits. 2. As a negative bias protector circuit is not built into the output pins, if negative bias is applied to the output pins, be sure to connect a freewheel diode between OUT and GND.
