STP16DPS05MTR

Overview

The STP16DPS05MTR is a monolithic, low-voltage, low-current power 16-bit shift register designed for LED 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 constant current. The device supports 20 V output driving capability and operates on a 3.3 V supply. Key specifications include a 30 MHz clock frequency, adjustable output current via external resistor, and integrated open/short circuit error detection. It is housed in a 24-SOP package.

Feature Summary

• Integrated short and open LED output error detection without increasing pin count
• Adjustable LED brightness from 0% to 100% via OE/DM2 pin
• High-speed data transmission supported by 30 MHz clock frequency
• Backward compatible with legacy STP16C/L596 series devices

Applications

• LED panel display systems
• Low voltage microcontroller interfacing
• High data rate LED matrix drivers
• Constant current LED sink applications

Procurement Notes

Verify the specific suffix 'MTR' against official datasheets to confirm tape-and-reel packaging configuration. Ensure compatibility with existing PCB footprints for the 24-SOP package. Confirm that the 3.3 V logic levels align with the host microcontroller interface requirements. Validate thermal performance expectations given the package's heat dissipation characteristics compared to standard TSSOP variants.

Selection Notes

Select this component when designing LED displays requiring integrated fault detection capabilities. It is suitable for applications needing high-speed serial data input at 30 MHz. Choose this part if backward compatibility with older STP16C/L596 designs is required while gaining enhanced diagnostic features. Consider the 24-SOP package constraints and the need for external resistors to set precise current levels.

Part Context

This device belongs to the STP16DP05 series of LED display drivers manufactured by STMicroelectronics. It represents an evolution in low-voltage LED driving technology, offering improved diagnostics over previous generations. The series is optimized for panel displays where reliability and error monitoring are critical. It serves as a specialized solution for managing large arrays of LEDs with minimal control lines.
