STP16CPPS05PTR

Overview

The STP16CPPS05PTR is a monolithic, low-voltage LED sink driver featuring sixteen constant current output channels. It operates with a supply voltage range of 3V to 5.5V and provides an output driving capability of up to 20V. The device regulates output currents between 3mA and 40mA, adjustable via an external resistor. It integrates a 16-bit serial-in, parallel-out shift register and storage register, supporting a maximum clock frequency of 30MHz for high-speed data transmission.

Feature Summary

Integrates patented auto power-saving technology that automatically reduces quiescent current when no active data is detected on the latches.
Features built-in LED error detection capabilities to monitor circuit integrity and ensure reliable operation.
Utilizes a TSSOP package with an exposed pad to significantly enhance thermal dissipation efficiency compared to standard packages.

Applications

Solar-powered traffic signs
Light box advertising displays
Stadium large screens

Procurement Notes

Verify the specific suffix PTR against official datasheets to confirm the tape and reel packaging configuration. Ensure compatibility with 3.3V microcontroller interfaces if used in low-voltage systems. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when precise brightness consistency across the entire visual area is required. The ±1% bit-to-bit accuracy makes it suitable for applications demanding uniform illumination. Choose this variant over non-PS versions specifically for its integrated automatic power management features.

Part Context

This part belongs to the STP16CPPS05 series of high-precision LED drivers from STMicroelectronics. The series includes variants such as STP16CPP05 and STP16DPPS05. This specific model distinguishes itself by combining high current control precision with proprietary power-saving algorithms and diagnostic functions.
