DESCRIPTION
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 0.4V (for 2 to 100mA LED current ) allows for more power efficient designs. A high-speed 4-wire serial interface of up to 25MHz clock 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 device also includes a blanking control pin (BLANK) that can be used to disable all channels independently of the interface. Thermal shutdown protection is incorporated in the device to disable the LED outputs if the die temperature exceeds a set limit. The device is available in the 24-lead SOIC, TSSOP, QSOP and the compact TQFN 4 x 4mm packages.

Doc. No. MD-5028 Rev. B 8 © Catalyst Semiconductor, Inc. Characteristics subject to change without notice PIN DESCRIPTION Name Function GND Ground SIN Serial data input pin CLK Serial clock input pin LATCH Latch serial data to output registers LED1-LED16 LED channel 1 to 16 cathode terminals BLANK Enable / disable all channels SOUT Serial data output pin. RSET LED current set pin VDD Positive supply Voltage TAB (TQFN package only) Connect to GND on the PCB PIN FUNCTION GND is the ground reference pin for the device. This pin must be connected to the ground plane on the PCB. SIN is the serial data input. Data is loaded into the internal register on each rising edge of CLK. CLK is the serial clock input. On each rising CLK edge, data is transferred from SIN to the internal 16- bit serial shift register. LATCH is the latch data input. On the rising edge of LATCH, data is loaded from the 16-bit serial shift register into the output regi ster latch. On the falling edge, this data is latched in the output register and isolated from the state of the serial shift register. LED1 - LED16 are the LED current sink channels. These pins are connected to the LED cathodes. The current sinks drive the LEDs with a current equal to 50 times RSET pin current. For the LED sink to operate correctly, the voltage on the LED pin must be above 0.4V. BLANK is the LED channel enable and disable input pin. When low, LEDs are enabled according to the output latch register content. When high, all LEDs are off, while preserving the data in the output latch register. SOUT is the serial data output of the 16-bit serial shift register. This pin is used to cascade several devices on the serial bus. The SOUT pin is then connected to the SIN input of the next device on the serial bus to cascade. RSET is the LED current setting pin. A resistor is connected between this pin and ground. Each LED channel current is set to 50 times the current pulled out of the pin. The RSET pin voltage is regulated to 1.2V. VDD is the positive supply pin voltage for the entire device. A small 1µF ceramic is recommended close to pin.
