STP16DPS05XTTR

Overview

The STP16DPS05XTTR 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 to drive LEDs. The device supports output open-circuit and short-circuit detection via dedicated logic sequences without additional pins. It operates with a supply voltage range of 3 V to 5.5 V, a maximum clock frequency of 30 MHz, and an operating temperature range of -40°C to +125°C. The component is housed in a 24-TSSOP package with exposed pad.

Feature Summary

• Integrated 16-bit constant current sink drivers with adjustable output current via external resistor
• Built-in diagnostic capabilities for detecting open circuits, ground shorts, and VO shorts on output lines
• High-speed serial data interface supporting up to 30 MHz clock frequency for rapid data transmission
• Enhanced thermal performance through TSSOP package with exposed pad design

Applications

• LED matrix display panels
• Low voltage LED indicator systems
• Microcontroller-driven lighting control interfaces

Procurement Notes

Verify the specific suffix XTTR against official datasheets to confirm tape-and-reel packaging and moisture sensitivity level. Ensure compatibility with 3.3 V logic levels if interfacing directly with microcontrollers. Confirm RoHS compliance status and environmental declarations prior to integration into final assemblies.

Selection Notes

Select this component when designing LED displays requiring integrated current regulation and fault detection within a low-voltage environment. The exposed pad package is suitable for applications needing improved heat dissipation compared to standard TSSOP variants. Consider the 30 MHz speed limit for high-refresh-rate display requirements.

Part Context

This part belongs to the STP16DP series of LED display drivers from STMicroelectronics. It is functionally similar to other members like STP16CP05 but includes specific diagnostic features for output line integrity monitoring. The series is optimized for driving large arrays of LEDs with minimal external components.

Replacement Considerations

STP16CPPS05XTTR and STP16DPPS05XTTR are listed as parameter-equivalent alternatives.
