2.5.1.
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.
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.
