tm TE CH Preliminary T6326A Low-Dropout, Constant-Current White LED with Channel Control FEATURES Up to 400mA LED Bias Current 3% LED Current Matching Simple LED Brightness Control www.DataSheet4U.com Low 0.05uA Shutdown Current 3V to 5.5V Supply Voltage Range MSOP-10L Package Output channel : MSOP-10L package for four channel LED1~4 Channels ON / OFF states: T6326A-AM with 16 channel states T6326A-BM with 5 channel states Build in Thermal Protect 140 °C GRNERAL DESCRIPTION The T6326A low-dropout bias supply for white LEDs is a high-performance alternative to the simple ballast resistors used in conventional white LED designs. The T6326A with internal channel on/off select function. The T6326A uses a single resistor to set the bias current for four LEDs, which are matched to 3%. The T6326A advantages over ballast resistors include significantly better LED to LED bias matching, much lower bias variation with supply voltage variation, significantly lower dropout voltage, and in some applications, significantly improved efficiency. The T6326A is available in MSOP-10L package.
