STP16DPPS05

Low voltage 16-bit constant current LED sink driver with output error

detection and auto power-saving

Datasheet

production data

LED panel displays. The device features 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 3 to 40 mA of constant current to drive the

LEDs. The STP16DPPS05 features open and

short LED detection on the outputs. The detection

circuit checks for 3 different conditions that can

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

or open line. The data detection results are

loaded in the shift registers and shifted out via the

serial line output. The detection functionality is

implemented without increasing the pin count,

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 exit from detection mode. The

Features

• Low voltage power supply down to 3 V

• 16 constant current output channels

• Adjustable output current through external

STP16DPPS05 output current can be adjusted

through an external resistor to control the light

intensity of the LEDs. LED brightness is

resistor

• Short and open output error detection

• Serial data IN/parallel data OUT

• Auto power-saving

adjustable from 0% to 100% via the OE/DM2 pin.

The auto power-shutdown and auto power-ON

feature allows the device to save power with no

external intervention. The STP16DPPS05

guarantees a 20 V output driving capability,

allowing users to connect more LEDs in series.

The high 30 MHz clock frequency makes the

device suitable for high data rate transmission.

The 3.3 V supply is well suited for applications

which interface a 3.3 V MCU. Compared to a

standard TSSOP package, the TSSOP with

exposed pad increases heat dissipation capability

by a factor of 2.5

• 3.3 V MCU-driving capability

• Output current: 3 to 40 mA

• 30 MHz clock frequency

• Available in high thermal efficiency TSSOP

exposed pad

• ESD protection: 2 kV HBM, 200 V MM
