STP16DP05B1R

Overview

The STP16DP05B1R 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 and sixteen regulated current sources providing 5-100 mA constant current. The device supports open and short LED detection on outputs without increasing pin count. It guarantees a 20 V output driving capability and operates with a high clock frequency of 30 MHz. The supply voltage ranges from 3 V to 5.5 V, making it suitable for 3.3 V microcontroller interfaces.

Feature Summary

• Integrated open and short circuit error detection on output lines
• Adjustable constant current output ranging from 5 mA to 100 mA via external resistor
• High-speed data transmission capability with 30 MHz clock frequency
• Compatibility with 3.3 V logic levels for direct microcontroller interfacing

Applications

• LED panel displays
• High data rate transmission systems
• Applications requiring output error detection

Procurement Notes

Verify the specific suffix B1R against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints, particularly regarding thermal dissipation requirements if using exposed pad variants. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when designing LED display systems that require integrated fault detection capabilities alongside standard shifting functions. It is appropriate for designs needing adjustable current drive up to 100 mA and operation at 3.3 V logic levels. Consider the 30 MHz clock speed for applications demanding high refresh rates or rapid data updates in large LED arrays.

Part Context

The STP16DP05 belongs to STMicroelectronics' family of low-voltage constant current LED sink drivers. It is backward compatible with the STP16C/L596 series. The device integrates 16-bit shift and storage registers with regulated current sources, offering a compact solution for driving multiple LEDs while providing diagnostic feedback through its detection mode.

Replacement Considerations

The STP16DP05 is documented as backward compatible with the STP16C/L596 series. Verify pinout and electrical characteristics against the specific legacy part number before substitution.
