STP16DPPS05XTTR

Overview

The STP16DPPS05XTTR is a low-voltage, 16-bit constant current LED sink driver manufactured by STMicroelectronics. It operates on a power supply voltage ranging from 3 V to 5.5 V and provides an output driving capability of up to 20 V. The device features sixteen regulated current sources with adjustable output currents between 3 mA and 40 mA, controlled via an external resistor. It supports a maximum clock frequency of 30 MHz and includes short and open output error detection capabilities.

Feature Summary

• Integrates sixteen constant current output channels for direct LED panel display driving
• Includes dedicated circuitry for detecting short-to-ground, short-to-Vo, and open-line output errors
• Supports auto power-saving modes to reduce energy consumption without external intervention
• Features thermal shutdown protection and ESD protection rated at 2.0 kV HBM

Applications

• LED panel displays requiring high data rate transmission
• Automotive applications utilizing AEC-Q100 qualified components
• Systems interfacing with 3.3 V microcontrollers
• Low voltage power supply driven LED arrays

Procurement Notes

Verify the specific package variant against project requirements, as the STP16DPPS05 series includes both SOIC-24 and HTSSOP-24 configurations. Confirm that the selected part matches the required thermal dissipation characteristics and pinout compatibility. Ensure compliance with RoHS standards and check for any specific automotive qualification needs if deploying in vehicle environments. Cross-reference datasheet revisions to guarantee parameter consistency.

Selection Notes

Select this component when designing systems requiring integrated error detection for LED outputs to enhance reliability. The 3.3 V MCU-driving capability simplifies interface design with modern processors. Consider the exposed pad package option if superior heat dissipation is necessary compared to standard TSSOP packages. Evaluate the 30 MHz clock speed against system timing constraints to ensure adequate data throughput for large display matrices.

Part Context

This device belongs to the STP16DPPS05 family of monolithic shift registers designed specifically for LED panel displays. It combines a 16-bit serial-in parallel-out shift register with a D-type storage register and regulated current sources. The family distinguishes itself through built-in diagnostic features and auto power management, offering a compact solution for managing multiple LED channels efficiently.

Replacement Considerations

Public confirmed substitutes include STAP16DPPS05XTTR and STP16CPPS05XTTR. Verify package compatibility and specific feature sets such as automotive qualification or error detection availability before substitution.
