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) uc 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 ro P Through an external resistor, users may adjust the STP16C596 output current, controlling in this way the light intensity of LEDs. so Ob - 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. du o te 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.
