The AP3609 is an eight-channel constant current sink with current match used for °C driver. It uses an external resistor to set the current for eight °C strings with an accuracy of ±1.5%. The full scale °C current can be adjusted from 10mA to 100mA for each channel. The °C light can be adjusted by PWM dimming function. The device can keep working when °C opens without damage. It features under voltage lockout protection and over temperature protection. The AP3609 has two interface terminals (FB and FBX). They enable the device to be connected in parallel.
