STP16CPS05TTR

Overview

The STP16CPS05TTR is a monolithic, low-voltage, low-current power 16-bit shift register designed for LED panel displays. It features a serial-in, parallel-out shift register feeding a D-type storage register with sixteen regulated constant current sources providing 5 mA to 100 mA per channel. The device supports a supply voltage range of 3 V to 5.5 V and guarantees a 20 V output driving capability. It operates at a maximum clock frequency of 30 MHz and includes auto power-saving features. The component is housed in a 24-TSSOP package.

Feature Summary

• Provides sixteen constant current output channels with adjustable intensity via external resistor
• Integrates auto power-shutdown and auto power-ON functionality to minimize quiescent current
• Supports high-speed data transmission with a maximum clock frequency of 30 MHz
• Features robust ESD protection rated at 2 kV HBM and 200 V MM

Applications

• LED panel displays
• High data rate transmission systems
• Applications interfacing with 3.3 V microcontrollers

Procurement Notes

Verify the specific suffix TTR corresponds to the Tape and Reel packaging configuration when ordering. Confirm that the 24-TSSOP footprint matches the target PCB design. Ensure the input voltage requirements align with the 3 V to 5.5 V operational range. Check for RoHS compliance status if environmental regulations apply to the final assembly. Validate the operating temperature range against the intended environment.

Selection Notes

Select this component for designs requiring precise constant current regulation for multiple LEDs without external drivers. It is suitable for systems needing serial data interfaces to reduce pin count. Consider the thermal performance of the TSSOP package for heat dissipation needs. Evaluate the 20 V output capability against the total forward voltage of series-connected LED strings. Ensure compatibility with the system's logic voltage levels.

Part Context

This part belongs to the STP16CP05 series from STMicroelectronics, which focuses on low-voltage LED driving solutions. The series integrates shift registers and constant current sinks into a single monolithic IC. Variants within the family may differ in package types or specific current ranges, but share the core 16-bit architecture and serial interface capabilities for display applications.
