STP16DPS05 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 were designed to provide 5-100 mA constant current to drive the LEDs. The STP16DPS05 features open and short LED detections on the outputs. The STP16DPS05 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 V or open line. O The data detection results are loaded in the shift register and shifted out via the serial line output. The detection functionality is implemented Features without increasing the pin count number, through Low voltage power supply down to 3 V a secondary function of the LATCH and output 16 constant current output channels enable pin (DM1 and DM2 respectively), a Adjustable output current through external dedicated logic sequence allows the device to resistor enter or leave from detection mode. Through an Short and open output error detection external resistor, users can adjust the Serial data IN/parallel data OUT STP16DPS05 output current, controlling in this 3.3 V micro driver-able way the light intensity of LEDs, in addition, user can adjust LEDs brightness intensity from 0% to Output current: 20-100 mA 30 MHz clock frequency 100% via OE/DM2 pin. Available in high thermal efficiency TSSOP exposed pad The STP16DPS05 guarantees a 20 V output ESD protection: 2 kV HBM, 200 V MM driving capability, allowing users to connect more LEDs in series. The high clock frequency, 30 MHz, makes the device suitable for high data Description rate transmission. The 3.3 V voltage supply is The STP16DPS05 is a monolithic, low voltage, well useful for applications that interface any low current power 16-bit shift register designed 3.3 V micro. Compared with a standard TSSOP for LED panel displays. The device contains a package, the TSSOP exposed pad increases 16-bit serial-in, parallel-out shift register that heat dissipation capability by a 2.5 factor.
