STP16CPC05XTTR

Overview

The STP16CPC05XTTR is a monolithic, low-voltage, 16-bit constant current LED sink driver designed for LED panel displays. It integrates a serial-in, parallel-out shift register feeding a D-type storage register with sixteen regulated current sources. The device operates on a supply voltage ranging from 3.0 V to 5.5 V and provides an output driving capability of up to 20 V. It supports adjustable output currents between 5 mA and 100 mA via an external resistor, features a maximum clock frequency of 30 MHz, and includes ESD protection rated at 2.5 kV HBM and 200 V MM.

Feature Summary

• Integrates a 16-bit shift register and storage register for serial data input and parallel output control.
• Provides sixteen independent constant current channels with adjustable output levels via an external resistor.
• Supports high-speed data transmission with a maximum clock frequency of 30 MHz.
• Features robust electrostatic discharge protection compliant with industrial standards.

Applications

• LED panel displays
• High data rate transmission systems
• Microcontroller-based lighting control interfaces

Procurement Notes

Verify the specific suffix XTTR corresponds to the Tape and Reel packaging configuration as documented in official distribution listings. Confirm that the component meets the required RoHS compliance and Ecopack2 environmental standards for your manufacturing process. Ensure the HTSSOP24 package dimensions align with your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a low-voltage power supply down to 3 V is required alongside compatibility with 3.3 V microcontrollers. Choose the STP16CPC05XTTR over variants like the STP16CPP05 if higher output current capabilities up to 100 mA are necessary rather than the lower range found in other family members. Consider the 20 V output capability for applications requiring more LEDs connected in series.

Part Context

This part belongs to the STP16CP05 series of low-voltage, low-current power 16-bit shift registers manufactured by STMicroelectronics. It serves as a specialized LED driver IC within the broader portfolio of display drivers. The device is distinct from similar parts like the STP16DPP05 or STP16CPP05 primarily through its specific output current range and package configuration, targeting general LED panel applications.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the STP16CP05MTR and STP16CPS05MTR. Verify pinout and thermal characteristics when transitioning between these variants to ensure system compatibility.
