STP16DP05

Low voltage 16-bit constant current

LED sink driver with outputs error detection

Features

■ Low voltage power supply down to 3 V

■ 16 constant current output channels

SO-24

QSOP-24

■ Adjustable output current through external

resistor

■ Short and open output error detection

■ Serial Data IN/Parallel data OUT

■ 3.3 V micro driver-able

TSSOP24

(exposed pad)

■ Output current: 5-100 mA

■ 30 MHz clock frequency

The data detection results are loaded in the shift

■ Available in high thermal efficiency TSSOP

exposed pad

The detection functionality is implemented without

increasing the pin count 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

from detection mode. Through an external

resistor, users can adjust the STP16DP05 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.

■ ESD protection 2.5 kV HBM, 200 V MM

Description

The STP16DP05 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-bitD-type storage register. In the output stage,

sixteen regulated current sources were designed

to provide 5-100 mA constant current to drive the

LEDs.

The STP16DP05 guarantees a 20 V output

driving capability, allowing users to connect more

LEDs in series. The high clock frequency,

30 MHz, makes the device suitable for high data

rate transmission. The 3.3 V voltage supply is well

useful for applications that interface any 3.3V

micro. Compared with a standard TSSOP

package, the TSSOP exposed pad increases heat

dissipation capability by a 2.5 factor.

The STP16DP05 features open and short LED

detections on the outputs.The STP16DP05 is

backward compatible with STP16C/L596.The

detection circuit checks 3 different conditions that

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

to V or open line.
