STAP08DP05

Low voltage 8-bit constant current LED sink driver with output error

detection for automotive applications

Datasheet

production data

Description

The STAP08DP05 is a monolithic, low voltage,

low current power 8-bit shift register designed for

LED panel displays. The STAP08DP05 contains

an 8-bit serial-in, parallel-out shift register that

feeds an 8-bit D-type storage register. In the

output stage, eight regulated current sources are

designed to provide 5-100 mA constant current to

drive the LEDs.

TSSOP16

(Exposed pad)

The detection circuit checks 3 different conditions

that can occur on the output line: short to GND,

short to V_Oor open line. The data detection

results are loaded in the shift register and shifted

out via the serial line output.

Features

• AECQ100 qualification

• Low voltage power supply down to 3 V

• 8 constant current output channels

STAP08DP05 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 STAP08DP05, thus controlling the

light intensity of the LEDs. In addition, the user

can adjust the intensity of the brightness of the

LEDs from 0% to 100% through the OE/DM2 pin.

• Adjustable output current through external

resistor

• Short and open output error detection

• Serial data IN/parallel data OUT

• Able to drive 3.3 V microcontroller

• Output current: 5-100 mA

• 30 MHz clock frequency

• Available in high thermal efficiency TSSOP

exposed pad

The STAP08DP05 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 that

interface any microcontroller from 3.3 V.

Compared with a standard TSSOP package, the

TSSOP exposed pad increases the capability of

heat dissipation by a factor of 2.5.

• ESD protection 2.5 kV HBM

Applications

• Dashboard and infotainment backlighting

• Exterior/interior lighting

• DTRLs
