STP16CPP05MTR

Overview

The STP16CPP05MTR is a monolithic, low-voltage, low-current power 16-bit shift register designed for LED panel displays. It features sixteen regulated current sources providing an adjustable output current range of 3 mA to 40 mA. The device supports a supply voltage of 3.3 V or 5 V and includes a high clock frequency of 30 MHz for high data rate transmission. It guarantees a 20 V output driving capability, allowing multiple LEDs to be connected in series. The component incorporates Schmitt-trigger inputs and ESD protection rated at 2 kV HBM.

Feature Summary

• Provides sixteen constant current output channels with adjustable brightness via an external resistor
• Features serial data input and parallel data output architecture for efficient control
• Includes thermal shutdown protection and robust ESD protection mechanisms

Applications

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

Procurement Notes

Verify the specific suffix 'MTR' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the 3-40 mA current range aligns with the target LED specifications. Ensure compatibility with the 3.3 V or 5 V supply voltage levels present in the design environment before finalizing procurement orders.

Selection Notes

Select this component when designing LED panels requiring precise constant current sinking with adjustable intensity. It is suitable for applications interfacing directly with 3.3 V logic without additional level shifting. Consider the 30 MHz clock speed for high-speed data requirements. Verify that the 20 V output capability meets the forward voltage sum of the series-connected LED strings in the circuit design.

Part Context

This part belongs to the STP16CPP05 series from STMicroelectronics, which are specialized low-voltage LED sink drivers. The series is engineered for monolithic integration of shift registers and storage registers to simplify display control architectures. These components are distinct from standard logic shift registers by their integrated constant current output stages optimized for direct LED driving.
