DATA SHEET www.onsemi.com 16-Channel Constant Current LED Driver CAT4016, CAV4016 TQFN24 TSSOP24 HV6 SUFFIX Y SUFFIX CASE 510AM Description CASE 948AR The CAT4016 is a 16 channel constant current driver for LED billboard and other general display applications. LED channel currents are programmed together via an external RSET resistor. Low output voltage operation on the LED channels as low as 0.4 V (for 2 to MARKING DIAGRAMS (Top Views) 100 mA LED current) allows for more power efficient designs. A high speed 4wire serial interface of up to 25 MHz clock TSSOP24 frequency controls each individual channel using a shift register and latch configuration. A serial output data pin (SOUT) allows multiple devices to be cascaded and programmed via one serial interface. The OAB CAT4016YO device also includes a blanking control pin (BLANK) that can be used 3YMXXX to disable all channels independently of the interface. Thermal shutdown protection is incorporated in the device to CAT4016Y = disable the LED outputs if the die temperature exceeds a set limit. CAT4016YT2 The device is available in the 24lead TSSOP and the compact TQFN24 TQFN 4 x 4 mm packages.
