STAP16DPPS05:Low voltage 16-bit constant current LED sink driver with output error detection and auto power-saving for automotive applications

The STAP16DPPS05 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 are designed to provide 3 to 40 mA of constant current to drive the LEDs.

The STAP16DPPS05 features the open and short LED detection on the outputs. The detection circuit checks 3 different conditions which may 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 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 detection mode. Through an external resistor, users can adjust the output current of the STP16DPPS05 thus controlling the light intensity of the LEDs. In addition, the user can adjust the intensity of the brightness of the LED’s from 0% to 100% through the OE/DM2 pin. The auto power shutdown and auto power-ON feature allows the device to save power with no external intervention. The STAP16DPPS05 guarantees a 20 V output driving capability, allowing users to connect more LEDs in series. The high clock frequency, 30 MHz also satisfies the system requirement of high volume data transmission. The 3.3 V of voltage supply is very useful for applications interfacing any microcontroller from 3.3 V micro. Compared with a standard TSSOP package, the TSSOP exposed pad increases the capability of heat dissipation by a factor of 2.5.
