Product overview
概要
The STP16DPS05 is a monolithic, low voltage, low current power 16-bit shift register designed for 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 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 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 a secondary function of the LATCH and output enable 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 STP16DPS05 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 STP16DPS05 guarantees a 20 V output driving capability, allowing users to connect more LEDs in series. The high clock frequency, 30 MHz, makes the 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. Compared with a standard TSSOP package, the TSSOP exposed pad increases heat dissipation capability by a 2.5 factor.
