STP16DPP05 Low voltage 16-bit constant current LED sink driver with output error detection Datasheet - production data 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 V or open line. The O 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 Features logic sequence allows the device to enter or exit from detection mode. The STP16DPP05 output Low voltage power supply down to 3 V current can be adjusted through an external 16 constant current output channels resistor to control the light intensity of the LEDs. Adjustable output current through external LED brightness is adjustable from 0% to 100% resistor via the OE/DM2 pin. The STP16DPP05 Short and open output error detection Serial data IN/parallel data OUT guarantees a 20 V output driving capability, 3.3 V MCU-driving capability allowing users to connect more LEDs in series. Output current: 3 to 40 mA The high 30 MHz clock frequency makes the 30 MHz clock frequency device suitable for high data rate transmission. Available in high thermal efficiency TSSOP The 3.3 V supply is well suited for applications which interface a 3.3 V MCU. Compared to a exposed pad standard TSSOP package, the TSSOP with ESD protection: 2 kV HBM, 200 V MM exposed pad increases heat dissipation capability by a factor of 2.5. Description 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 Table 1: Device summary Order code Package Packing STP16DPP05MTR SO-24 (tape and reel) 1000 parts per reel STP16DPP05TTR TSSOP24 (tape and reel) 2500 parts per reel STP16DPP05XTTR TSSOP24 exposed pad (tape and reel) 2500 parts per reel STP16DPP05PTR QSOP-24 2500 parts per reel April 2017 DocID16518 Rev 4 1/34 www.st.com This is information on a product in full production.
