Wide Peng launched 2 pin LED protection IC AMC7169 and A716

Analog IC design manufacturers wide Peng Technology (ADDtek) introduced 2 pin LED protection IC - AMC7169 and A716, can solve the problem of LED series, and protect the LED from excessive current or reverse current damage. Peng Peng said that in the application of LED lighting and LED backlight, often require multiple LED Series in order to simplify the circuit and reduce costs. However, when a LED is damaged and the circuit is broken, the whole LED string will not work properly, which will affect the overall performance of the product.

The ADDtek LED protects the IC and connects the LED at both ends of the IC when the LED is working to protect it from entering the monitoring mode without affecting the system operation. When the LED is damaged and broken, causing both ends of the voltage rises to protect IC built-in voltage protection point, IC will enter the protected mode, the original should be the current through the LED guide through the protection of IC to the next LED, let LED on the rest of the LED can still work normally, when the voltage at both ends of the IC will be far more protection the forward voltage is lower than LED, in order to reduce the waste of energy.

In addition, when the assembly error will be connected to the LED module and the drive circuit module polarity reverse, the protection of the IC will enter the reverse mode, guide the reverse current flow through the protection of IC to avoid damage to LED. The use of 2mm x 2mm x DFN 0.8mm package AMC7169 (500mA), A716 (350mA) ESD protection capacity of up to HBM 2KV, to protect the power of less than 2W LED, wide Peng will be launched to protect 3W and 5W products.
