STP08DP05XTTR

Overview

The STP08DP05XTTR is a low-voltage, low-current power 8-bit shift register designed for LED panel displays. It features eight regulated constant current sources providing 5-100 mA to drive LEDs. The device includes open and short detection on outputs, checking conditions such as short to GND, short to VO, or open line. Data detection results are shifted out via the serial line output. It supports a high clock frequency of 30 MHz and guarantees a 20 V output driving capability. The supply voltage ranges from 3 V to 5.5 V, with a maximum supply current of 13.5 mA. It operates within a temperature range of -40°C to +125°C and is housed in a 16-HTSSOP package.

Feature Summary

• Integrated error detection circuitry identifies short-to-ground, short-to-Vo, and open-line conditions on output channels without increasing pin count.
• High-speed serial data transmission capability supported by a 30 MHz clock frequency for efficient system data handling.
• Enhanced thermal performance through an exposed pad design in the TSSOP package, improving heat dissipation compared to standard packages.

Applications

• LED panel displays
• Low-voltage microcontroller interfacing
• Constant current LED sink drivers

Procurement Notes

Verify the specific suffix XTTR corresponds to the 16-HTSSOP package and reel packaging configuration. Confirm that the 5-100 mA adjustable current range aligns with the external resistor selection for the target application. Ensure compatibility with 3.3 V logic levels for serial input and control signals. Check for any specific RoHS compliance documentation required for the region of deployment.

Selection Notes

Select this component when requiring integrated fault detection alongside constant current driving in a compact surface-mount form factor. The 20 V output capability allows for series-connected LED strings. Consider the 16-HTSSOP exposed pad for thermal management needs. Verify that the 30 MHz clock speed meets the bandwidth requirements of the display system. Ensure the 3 V minimum supply voltage matches the available power rail.

Part Context

This part belongs to the STP08DP05 series of low-voltage LED display drivers. It is backward compatible in functionality and footprint with the STP8C/L596 series but extends functionality with built-in output error detection. The series is designed for monolithic integration of shift registers and storage registers with regulated current sources for direct LED driving.
