Hot-plugging Protection

This feature protects LEDs when connecting to a driver that is already powered on. This is disabled by default

and can be enabled through the Inventronics Programing software.

LED threshold voltage (Vth) is the minimum voltage required for

current to flow through the LED load. After this threshold is met, the

LED forward voltage (Vf) increases as the current increases.

Set Vth close to, but higher than the actual LED threshold voltage for

optimized performance. The greater the difference between the Vth

setting and the actual LED threshold voltage, the higher the overshoot

current will be. The Vth setting must be lower than Vf.

Please test, program, and tune this feature for each LED load design.

Parallel LED Protection

This feature helps protect parallel LEDs from a high, overcurrent condition by limiting the voltage. This is disabled

by default and can be enabled through the Inventronics Programing software.

Set V_overload close to, but higher than the maximum forward voltage

for optimized performance. The greater the difference between the

V_overload setting and the maximum forward voltage, the higher the

overload stress will be. The V_overload setting must be higher than

Vf.

Please test, program, and tune this feature for each LED load design.
