STP16DP05PTR STMicroelectronics

STP16DP05 Low voltage 16-bit constant current LED sink driver with outputs error detection Datasheet - production data LED panel displays. The device 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 were designed to provide 5-100 mA constant current to drive the LEDs. The STP16DP05 features open and short LED detections on the outputs. The STP16DP05 is backward compatible with STP16C/L596. The detection circuit checks 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 register and shifted out via the serial line output. The detection functionality is implemented without increasing the pin count number, through Features a secondary function of the output enable and latch pin (DM1 and DM2 respectively), a Low voltage power supply down to 3 V dedicated logic sequence allows the device to 16 constant current output channels enter or leave from detection mode. Through an Adjustable output current through external external resistor, users can adjust the resistor STP16DP05 output current, controlling in this Short and open output error detection way the light intensity of LEDs, in addition, user Serial data IN/Parallel data OUT can adjust LEDs brightness intensity from 0 % to 3.3 V micro driver-able 100 % via OE/DM2 pin. The STP16DP05 Output current: 5-100 mA 30 MHz clock frequency guarantees a 20 V output driving capability, Available in high thermal efficiency TSSOP allowing users to connect more LEDs in series. exposed pad The high clock frequency, 30 MHz, makes the ESD protection 2.5 kV HBM, 200 V MM device suitable for high data rate transmission. The 3.3 V voltage supply is well useful for applications that interface any 3.3 V micro. Description Compared with a standard TSSOP package, the The STP16DP05 is a monolithic, low voltage, low TSSOP exposed pad increases heat dissipation current power 16-bit shift register designed for capability by a 2.5 factor.
