STAP16DPPS05XTTR

Overview

The STAP16DPPS05XTTR is a low-voltage, 16-bit constant current LED sink driver designed for automotive LED panel displays. It features AEC-Q100 qualification and operates with a supply voltage from 3 V to 5.5 V. The device provides sixteen regulated current sources adjustable between 3 mA and 40 mA via an external resistor. Key technical specifications include a maximum clock frequency of 30 MHz, a 20 V output driving capability, and integrated short/open circuit error detection. It supports auto power-saving modes and thermal shutdown protection within an operating temperature range of -40°C to 125°C.

Feature Summary

• Integrated open and short LED detection on outputs without increasing pin count
• Auto power-saving and auto power-on features for energy efficiency
• High-speed serial data transmission with 30 MHz clock frequency
• Enhanced thermal dissipation through exposed pad package design

Applications

• Automotive LED panel displays
• Low voltage LED sink drive systems
• Microcontroller interfacing requiring 3.3 V logic compatibility

Procurement Notes

Verify component authenticity against the official STMicroelectronics datasheet. Confirm the HTSSOP-24 package type and AEC-Q100 automotive grade status. Check for End-of-Life (EOL) notifications as discontinuation information may be present in public records. Ensure ordering suffixes match the required reel or cut tape packaging format specified in the manufacturer documentation.

Selection Notes

Select this component for designs requiring automotive-grade reliability and integrated fault detection. The 16-bit architecture simplifies control interface requirements compared to parallel drivers. Consider the 3 to 40 mA adjustable current range for brightness control flexibility. Evaluate the thermal performance benefits of the exposed pad package for high-density applications.
