  • The STP16DPP05 is a monolithic, low voltage, low current power 16-bit shift register designed for LED panel displays. The device features 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 3 to 40 mA of constant current to drive the LEDs. The STP16DPP05 features open and short LED detection on the outputs. The detection circuit checks for 3 different conditions that can occur on the output line: short to GND, short to VO or open line. The data detection results are loaded in the shift registers and shifted out via the serial line output. The detection functionality is implemented without increasing the pin count, through a secondary function of the output enable and latch pin (DM1 and DM2 respectively). A dedicated logic sequence allows the device to enter or exit from detection mode. The STP16DPP05 output current can be adjusted through an external resistor to control the light intensity of the LEDs. LED brightness is adjustable from 0% to 100% via the OE/DM2 pin. The STP16DPP05 guarantees a 20 V output driving capability, allowing users to connect more LEDs in series. The high 30 MHz clock frequency makes the device suitable for high data rate transmission. The 3.3 V supply is well suited for applications which interface a 3.3 V MCU. Compared to a standard TSSOP package, the TSSOP with exposed pad increases heat dissipation capability by a factor of 2.5.
