STP16DP05TTR

Overview

The STP16DP05TTR is a low-voltage, 16-bit constant current LED sink driver designed for panel displays. It integrates a serial-in parallel-out shift register and D-type storage register with sixteen regulated current sources providing 5 mA to 100 mA per channel. The device supports a 3 V to 5.5 V supply, 20 V output capability, and 30 MHz clock frequency. It features open/short circuit detection and PWM dimming via the OE pin.

Feature Summary

• Integrated error detection for short-to-ground, short-to-Vo, and open-line conditions
• Adjustable output current from 5 mA to 100 mA using a single external resistor
• Supports global brightness control via the Output Enable pin
• Backward compatible with standard shift register interfaces

Applications

• LED matrix panel displays
• High data rate transmission systems
• 3.3 V microcontroller interfacing

Procurement Notes

Verify the specific suffix 'TTR' against the manufacturer datasheet to confirm tape-and-reel packaging and exact electrical tolerances. Ensure the design accounts for the exposed pad thermal requirements of the TSSOP-24 package. Cross-reference the part number with official STMicroelectronics documentation to validate availability and revision status before procurement.

Selection Notes

Select this component when diagnostic feedback on LED integrity is required. The integrated detection logic eliminates the need for external monitoring circuits. The wide current range allows flexibility in LED selection without changing the driver architecture. Verify that the application requires serial input compatibility with existing shift register designs.

Part Context

This part belongs to the STP16DP05 series, which focuses on reliability through built-in diagnostics. Unlike basic drivers, it provides real-time fault reporting via the serial output line. The series is engineered for industrial and commercial display applications where maintenance access is limited and system uptime is critical.

Replacement Considerations

The STP16DP05 is backward compatible with the STP16C/L596. When substituting, verify that the replacement part supports the same 20 V output voltage and 100 mA maximum current rating. Confirm that the diagnostic pin mapping remains identical to avoid PCB redesign.
