STAP16DPS05

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 STAP16DPS05 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 5-100 mA constant current to drive the

LEDs.

The STAP16DPS05 features the open and short

LED detections on the outputs.The

STAP16DPS05 ensures the backward

Features

compatibility with the STP16C/L596. The

detection circuit checks 3 different conditions,

which 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. 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 STAP16DPS05, 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. The STAP16DPS05 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 micro. Compared with a standard

TSSOP package, the TSSOP exposed pad

increases the capability of heat dissipation by a

factor of 2.5.
