STP24DP05

24-bit constant current

LED sink driver with output error detection

Features

■ Low voltage power supply down to 3 V

■ 8 x 3 constant current output channels

■ Adjustable output current through external

resistors

■ Short and open output error detection

■ Serial data IN/Parallel data OUT

■ Shift register data flow registers control

■ Accepts 3.3 V and 5 V micro driver

■ Output current: 5-80 mA

TQFP48

The data detection results are loaded in the shift

registers and shifted out via the serial line output.

The detection functionality is activated with a

dedicated pin or as alternative, through a logic

sequence that allows the user to enter or exit from

detection mode.

■ 25 MHz clock frequency

■ High thermal efficiency package

Through three external resistors, users can adjust

the output current for each 8-channel group,

controlling in this way the light intensity of LEDs.

Description

The STP24DP05 is a monolithic, low voltage, low

current power 24-bit shift register designed for

LED panel displays. The device contains a

8 x 3-bit serial-in, parallel-out shift register that

feeds a 8 x 3-bit D-type storage register. In the

output stage, twenty-four regulated current

sources were designed to provide 5-80 mA

constant current to drive the LEDs.

The STP24DP05 guarantees a 20 V output

driving capability, allowing users to connect more

LEDs in series.

The high clock frequency, 25 MHz, makes the

device suitable for high data rate transmission.

The 3.3 V of voltage supply is useful for

applications that interface any micro from 3.3 V.

The 8x3 shift registers data flow sequence order

can be managed with two dedicated pins.

The STP24DP05 has a dedicated pin to activate

the outputs with a sequential delay, that will

prevent inrush current during outputs turn-ON.

The device detection circuit checks 3 different

conditions that can occur on the output line: short

to GND, short to V or open line.
