STP04CM05MTR

Overview

The STP04CM05MTR is a monolithic, low-voltage, high-power LED sink driver and 4-bit shift register designed for power-LED applications. It integrates a 4-bit serial-in, parallel-out shift register feeding a D-type storage register, with four regulated current sources providing 80 mA to 400 mA constant current. The device guarantees a 20 V output driving capability and supports a maximum clock frequency of 30 MHz. It operates on a supply voltage range compatible with 3.3 V microcontrollers and includes UVLO, POR, and thermal shutdown protection.

Feature Summary

• Integrates a 4-bit shift register with four constant current output channels for high-power LED driving
• Features adjustable output current via a single external resistor within the 80 mA to 400 mA range
• Supports high-speed data transmission with a 30 MHz clock frequency
• Includes comprehensive protection mechanisms such as under-voltage lockout, power-on reset, and thermal shutdown

Applications

• Very high brightness displays
• Special lighting applications
• Power-LED panel systems

Procurement Notes

Verify the specific suffix 'MTR' against the manufacturer's official documentation to confirm the tape-and-reel packaging configuration. Ensure the component meets RoHS compliance standards required for your target market. Cross-reference the exact part number with the latest datasheet revision to confirm active status and availability of design files.

Selection Notes

Select this component when designing circuits requiring high-current sinking capabilities up to 400 mA per channel. It is suitable for systems needing serial data input with parallel output distribution. Consider the TSSOP16 exposed pad package for its enhanced thermal dissipation properties compared to standard packages. Verify that the 20 V output capability aligns with the series LED string requirements.

Part Context

This part belongs to the STP04CM series of constant current power-LED sink drivers from STMicroelectronics. It is specifically engineered for applications demanding high brightness and efficient heat management. The series utilizes a TSSOP16 exposed pad package to improve thermal performance, distinguishing it from lower-power variants in the broader LED driver portfolio.
