STAP16DPS05XTTR

Overview

The STAP16DPS05XTTR is a low-voltage, 16-bit constant current LED sink driver designed for automotive applications. It features AEC-Q100 qualification and operates with a supply voltage range of 3V to 5.5V. The device provides sixteen regulated current sources capable of delivering output currents between 3mA and 40mA, adjustable via an external resistor. It supports a maximum clock frequency of 30MHz and includes open and short circuit error detection on outputs. The component utilizes a 24-TSSOP package with an exposed pad for enhanced thermal dissipation.

Feature Summary

AEC-Q100 qualified for automotive reliability standards
Integrated open and short LED output error detection
Auto power-saving mode functionality
High-speed serial data transmission capability

Applications

Automotive LED panel displays
High-brightness LED array drivers
LED backlighting systems requiring diagnostics

Procurement Notes

Verify the specific suffix XTTR corresponds to the Tape and Reel packaging configuration required for automated assembly processes. Confirm that the automotive grade designation aligns with project reliability requirements. Ensure the 24-TSSOP-EP footprint matches the PCB layout specifications. Check for any recent Product Change Notifications regarding manufacturing site or material composition updates.

Selection Notes

Select this component when automotive certification is mandatory and integrated fault detection is required. It serves as a suitable replacement for legacy parts like the STP16C/L596 series while offering improved diagnostic capabilities. Consider the exposed pad thermal design if operating near maximum temperature limits. Verify compatibility with 3.3V microcontroller logic levels for direct interface without additional level shifting.

Part Context

This part belongs to the STAP16DPPS05 family of low-power LED drivers. It shares architectural similarities with the STP16DPS05 but includes specific automotive qualifications and auto power-saving features. The device integrates a 16-bit shift register and storage register to manage parallel LED outputs efficiently. It is distinct from non-automotive variants by its rigorous qualification standards and extended temperature performance.
