STP16DP05PTR

Overview

The STP16DP05PTR is a low-voltage, 16-bit constant current LED sink driver designed for panel displays. It features a serial-in, parallel-out shift register feeding a D-type storage register with sixteen regulated current sources providing 5-100 mA output. The device supports open and short LED detection via OE/DM2 pin logic sequences without increasing pin count. It offers 30 MHz clock frequency, 20 V output driving capability, and operates on a 3.3 V supply. The TSSOP exposed pad package enhances heat dissipation by 2.5 times compared to standard packages.

Feature Summary

• Integrated error detection for open and short circuits on output lines
• Adjustable output current ranging from 5 to 100 mA via external resistor
• High-speed data transmission supported by 30 MHz clock frequency
• Enhanced thermal performance through TSSOP exposed pad design

Applications

• LED panel displays
• Low voltage LED matrix systems
• Microcontroller-based lighting control interfaces

Procurement Notes

Verify the specific suffix PTR against official STMicroelectronics documentation to confirm packaging configuration and availability status. Cross-reference the part number with current product lifecycle notices to ensure active production or obsolescence status. Confirm RoHS compliance and moisture sensitivity levels prior to procurement integration.

Selection Notes

Select this component for applications requiring precise constant current regulation and diagnostic feedback on LED integrity. The 3.3 V compatibility ensures direct interfacing with modern microcontrollers. Consider the exposed pad requirement for thermal management in high-density layouts where heat dissipation is critical for sustained operation.

Part Context

The STP16DP05 belongs to a series of monolithic LED drivers offering backward compatibility with older models like the STP16C/L596. It integrates shift registers, storage latches, and current sources into a single chip, simplifying circuit design for large-scale LED arrays while maintaining low power consumption and high reliability standards.

Replacement Considerations

Public confirmed substitute part numbers include STP16CPPS05XTTR and STP16DPPS05XTTR. Verify electrical parameter equivalence and pinout compatibility before substitution.
