Catalyst listed 8 channel constant current drain type LED driver IC for large size LED display

America Catalyst semiconductor listed 8 channel constant current sink type LED driver IC "CAT4008" mainly for large size display billboard. The driver IC is equipped with a maximum clock frequency 25MHz 4 wire serial interface. Each channel can be controlled externally. LED current according to the external resistance, can be set between 2 ~ 100mA. The output voltage of LED is more than 0.4V. When the LED current is 30mA, the dropout voltage is 300mV. The driver IC is equipped with a control terminal for blanking. Therefore, regardless of how each channel is set, all channels are invalid. In addition, it is also equipped with overheating protection circuit, when the chip temperature exceeds the set range, the LED output is invalid. Package using 16 pin SOIC. 10 thousand bulk purchase price of $0.49. Supply is now available. After the start of production, after receiving the order delivery date is scheduled for 6 ~ 8 weeks.
