STP16C596 16-Bit, constant current LED sink driver Features ■ 16 constant current output channels ■ Adjustable output current through external resistor ■ Serial data IN/parallel data OUT ■ Serial out change state on the falling edges of clock ■ Output current: 15-120 ma ■ 25MHz clock frequency ■ Available in high thermal TSSOP exposed pad ■ Efficiency package DIP-24 SO-24 TSSOP24 TSSOP24 (exposed pad) c u d Description The STP16C596 is a monolithic, medium-voltage, low current power 16-bit shift register designed for LED panel displays. The STP16C596 contains a 16-bit serial-IN, parallel-OUT shift register that feeds a 16-bit, D-type storage register. In the output stage, sixteen regulated current sources are designed to provide 15-120mA constant current to drive the LEDs. ) s ( ct o r P Through an external resistor, users may adjust the STP16C596 output current, controlling in this way the light intensity of LEDs. o s b O - The serial output change state on the falling edges of clock, this special feature will provide an improved performance of the application when the clock signal is skewed because the daisy chain is too long. u d o e t le ) s t( The STP16C596 guarantees a 16V output driving capability, allowing users to connect more LEDs in series. The high clock frequency, 25MHz, also satisfies the system demand for high volume data transmission. Compared with a standard TSSOP package, the TSSOP exposed pad increases heat dissipation capability by a 2.5 factor. r P e t e l o s b O Order codes Part Number Package Packaging STP16C596B1R DIP-24 15 parts per tube STP16C596M SO-24 (Tube) 40 parts per tube STP16C596MTR SO-24 (Tape & Reel) 1000 parts per reel STP16C596TTR TSSOP24 (Tape & Reel) 2500 parts per reel STP16C596XTTR TSSOP24 Exposed-Pad (Tape & Reel) 2500 parts per reel July 2006 Rev 10 1/24 www.st.com 24 STP16C596 Contents Contents 1 2 Summary description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 1.1 Pin connection and description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 1.2 Equivalent circuit of inputs and outputs . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 1.3 Block diagram . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 1.4 Truth table . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 1.5 Timing diagrams . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 Maximum rating . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9 2.1 Thermal data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9 2.2 Recommended operating conditions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 c u d ) s t( 3 Electrical characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 11 4 Switching characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12 5 Test circuit . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 13 6 Typical characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 14 7 Package mechanical data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16 8 Revision history . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 23 e t le ) s ( ct u d o r P e t e l o s b O 2/24 o r P o s b O - STP16C596 1 Summary description Summary description Table 1.
