AMC7169WF ADDTEK [ADDtek Corp], AMC7169WF Datasheet - Page 3

• Manufacturer Part Number: AMC7169WF
• Description: 500mA LED PROTECTOR
• Manufacturer: ADDTEK [ADDtek Corp]

Monitoring Mode:
5.0V. All AMC7169 at monitoring mode would only sink ~uA current from the system.
Triggered Mode:
drop across adjacent AMC7169 starts to increase, and then AMC7169 will be trigged when the voltage drop reaches 5V.
The dropout voltage on AMC7169 will be around 1V and the LED current I
will work well except the abnormal LED bypassed.
Reverse Mode:
turned-on to bypass the current. Such that the reverse voltage on LEDs was reduced to prevent LED damage.

When the LED string was reversed connected to the driver, the AMC7169 build-in reverse protection diode was
The forward voltage drop (Vf) of all LEDs should be less than 4V, which is lower than AMC7169 trigger voltage
Any LED may become open circuit because of LED damage or wiring problem. When it happens, the voltage
