STP16DPPS05TTR

Overview

The STP16DPPS05TTR is a low-voltage, low-current power 16-bit shift register designed for LED panel displays. It features a serial-in, parallel-out architecture with sixteen regulated constant current sources providing 3 to 40 mA per channel. The device supports open and short LED detection via the OE/DM2 pin without increasing pin count. It operates on a 3 V supply, interfaces directly with 3.3 V MCUs, and supports clock frequencies up to 30 MHz. The TSSOP-24 package includes an exposed pad for enhanced thermal dissipation.

Feature Summary

• Integrated open and short circuit detection for output lines
• Adjustable constant current output via external resistor
• Auto power-shutdown and auto power-on capabilities
• High-speed data transmission support

Applications

• LED panel displays
• Traffic signs
• Light box advertisements
• Stadium large screens
• Battery or solar-powered signage

Procurement Notes

Verify the specific suffix XTTR against official datasheets to confirm packaging details and RoHS compliance status. Confirm the manufacturer part number matches the required TSSOP-24 package with exposed pad. Ensure compatibility with 3.3 V logic levels and check for any recent product change notifications affecting availability or specifications.

Selection Notes

Select this component when designing LED displays requiring integrated fault detection and high brightness consistency. It is suitable for applications needing direct 3.3 V MCU interfacing and adjustable current control. Consider the exposed pad thermal requirements for high-density layouts. Verify that the 30 MHz clock speed meets system timing constraints.

Part Context

This part belongs to the STP16DPPS05 series of LED display drivers from STMicroelectronics. It shares core functionalities with variants like STP16CPPS05 but differs in specific package and electrical characteristics. The series targets high-reliability outdoor and indoor signage applications requiring precise current regulation and diagnostic features.
