STP16DP05XTTR

Overview

The STP16DP05XTTR is a low-voltage, 16-bit constant current LED sink driver designed for LED panel displays. It features a serial-in, parallel-out shift register feeding a D-type storage register. The device provides regulated current sources of 5-100 mA to drive LEDs and supports a maximum output voltage of 20 V. It operates with a supply voltage range of 3 V to 5.5 V and supports a clock frequency up to 30 MHz. The component includes open and short circuit error detection capabilities and utilizes a TSSOP-24 package with an exposed pad for enhanced thermal dissipation.

Feature Summary

• Integrates 16-bit shift register and D-type storage for serial data input and parallel output control.
• Provides adjustable constant current output ranging from 5 mA to 100 mA via an external resistor.
• Features built-in diagnostic circuits for detecting open lines and short circuits on output channels.
• Supports high-speed data transmission with a clock frequency capability of up to 30 MHz.

Applications

• LED panel displays
• High brightness LED matrix systems
• Digital signage applications

Procurement Notes

Verify the specific suffix XTTR corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the exposed pad thermal design aligns with the target PCB layout for adequate heat dissipation. Ensure compatibility with 3.3 V microcontroller logic levels for reliable signal interfacing. Check for any specific moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Choose this component when designing systems requiring integrated error detection for output line integrity. Select this model if the application demands high clock speeds for rapid data updates in LED matrices. Consider the exposed pad package for improved thermal performance compared to standard packages. Verify that the 20 V output capability meets the series LED voltage requirements of the display architecture.
