STAP16DPPS05

Low voltage 16-bit constant current LED sink driver with output error

detection and auto power-saving for automotive applications

Datasheet

production data

Description

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 V_O

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
