STP08DP05 Low voltage 8-bit constant current LED sink with full outputs error detection Datasheet - production data serial-in, parallel-out shift register that feeds a 8- bitD-type storage register. In the output stage, eight regulated current sources were designed to provide 5-100 mA constant current to drive the LEDs. DIP-16 TSSOP16 The STP08DP05 is backward compatible in the (Exposed pad) functionality and footprint with STP8C/L596 and extends its functionality with open and short detection on the outputs. The detection circuit checks 3 different conditions that can occur on TSSOP16 the output line: short to GND, short to V or open O SO-16 line. The data detection results are loaded in the shift register and shifted out via the serial line Features output. The detection functionality is implemented without Low voltage power supply down to 3 V increasing the pin number, through a secondary 8 constant current output channels function of the output enable and latch pin (DM1 Adjustable output current through external and DM2 respectively), a dedicated logic resistor sequence allows the device to enter or leave from detection mode. Through an external resistor, Short and open output error detection users can adjust the STP08DP05 output current, Serial data IN/parallel data OUT controlling in this way the light intensity of LEDs, 3.3 V micro driver-able in addition, user can adjust LEDs brightness intensity from 0% to 100% via OE/DM2 pin. Output current: 5-100 mA 30 MHz clock frequency The STP08DP05 guarantees a 20 V output driving capability, allowing users to connect more Available in high thermal efficiency TSSOP LEDs in series. The high clock frequency, exposed pad 30 MHz, also satisfies the system requirement of ESD protection 2.5 kV HBM, 200 V MM high volume data transmission. The 3.3 V of voltage supply is well useful for applications that Description interface any micro from 3.3 V. Compared with a standard TSSOP package, the TSSOP exposed The STP08DP05 is a monolithic, low voltage, low pad increases heat dissipation capability by a 2.5 current power 8-bit shift register designed for LED factor. panel displays. The STP08DP05 contains a 8-bit Table 1.
