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 a secondary function of the output enable and latch pin (DM1 and DM2 respectively), a dedicated logic sequence allows the device to enter or leave from detection mode. Through an external resistor, users can adjust the STP16DP05 output current, controlling in this way the light intensity of LEDs, in addition, user can adjust LED’s brightness intensity from 0% to 100% via OE/DM2 pin. The STP16DP05 guarantees a 20V output driving capability, allowing users to connect more LEDs in series. The high clock frequency, 30MHz, makes the device suitable for high data rate transmission. The 3.3V voltage supply is well useful for applications that interface any 3.3V micro. Compared with a standard TSSOP package, the TSSOP exposed pad increases heat dissipation capability by a 2.5 factor.
