STP08DP05

Low voltage 8-Bit constant current

Led sink with full outputs error detection

Features

■ Low voltage power supply down to 3V

■ 8 constant current output channels

Dip-16

■ Adjustable output current through external

TSSOP16

(Exposed pad)

resistor

■ Short and open output error detection

■ Serial Data IN/Parallel data OUT

■ 3.3V micro driver-able

■ Output current: 5-100mA

TSSOP16

SO-16

■ 30MHz clock frequency

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

■ Available in high thermal efficiency TSSOP

exposed pad

■ ESD protection 2.5kV HBM, 200V MM

sequence allows the device to enter or leave from

detection mode. Through an external resistor,

users can adjust the STP08DP05 output current,

controlling in this way the light intensity of LEDs,

in addition, user can adjust LED’s brightness

intensity from 0% to 100% via OE/DM2 pin.

Description

The STP08DP05 is a monolithic, low voltage, low

current power 8-bit shift register designed for LED

panel displays. The STP08DP05 contains a 8-bit

serial-in, parallel-out shift register that feeds a 8-

bitD-type storage register. In the output stage,

eight regulated current sources were designed to

provide 5-100mA constant current to drive the

LEDs.

The STP08DP05 guarantees a 20V output driving

capability, allowing users to connect more LEDs in

series. The high clock frequency, 30MHz, also

satisfies the system requirement of high volume

data transmission. The 3.3V of voltage supply is

well useful for applications that interface any

micro from 3.3V. Compared with a standard

TSSOP package, the TSSOP exposed pad

increases heat dissipation capability by a 2.5

factor..

The STP08DP05 is backward compatible in the

functionality and footprint with STP8C/L596 and

extends its functionality with open and short

detection on the outputs. The detection circuit

checks 3 different conditions that can occur on the

output line: short to GND, short to V or open line.

The data detection results are loaded in the shift
