ZLED7002 Protection Features

2.5.1.

Over-Temperature Protection

The ZLED7002 includes protection from damage due to over-temperature conditions. The ZLED7002 automatically turns off if

its temperature is ≥160°C (typical). If the temperature returns to ≤140°C, the ZLED7002 turns on and continues normal

operation.

2.5.2.

Main LED Short-Circuit Protection

The ZLED7002 will detect a short-circuit on the MAIN LED. In this case, the ZLED7002 automatically turns off the MAIN LED

channel and activates the SUB LED channel.
