t(s V-LED supply error detection

c ■ Serial data in/parallel data out

u ■ Serial out change state on the falling edges of

rod clock

P t(s) ■ Output current: 20-120mA

te c ■ 3.3V micro driver-able

le u ■ 25MHz clock frequency

so rod ■ Available in high thermal TSSOP exposed pad.

- Ob te P Description

) le The STP08CDC596 is a monolithic, medium-

t(s o voltage, low current power 8-bit shift register

c bs designed for LED panel display. The

u STP08CDC596 contains a 8-bit serial-in, parallel-

d - O out shift register that feeds a 8-bitD-type storage

ro ) register. In the output stage, eight regulated

P t(s current sources were designed to provide 15-

120mA constant current to drive the LEDs.

lete uc The STP08CDC596 contains the built-IN error

d detection feature. The device performs this

so ro additional function without any increase of the pin

number and any change of the pin function, if

b P compared to the standard device without error

O te detection. Consequently, choosing this device

le does not mean to change the footprint on the

o board.

To perform this functionality mode, the device

needs a digital key coming from the

Microprocessor. The STP08CDC596 is able to

detect: open and short on the LED line, short to

GND, short to LED voltage supply. The data

mapping of output channels status detection is

provided by a feedback from the serial output to

the Microprocessor.

Trough an external resistor, users may adjust the

STP08CDC596 output current, controlling the

light intensity of LEDs.

The STP08CDC596 guarantees 16V output

driving capability, allowing users to connect more

LEDs in series. The high clock frequency, 25

MHz, also satisfies the system requirement of

high volume data transmission.

The device is offered in DIP-16, SO-16,

TSSOP-16 and TSSOP-16 Exposed Pad

packages.

The STP08CDC596 is well suitable for traffic

display signs where the detection feature is

strongly required.
