Overview
The STP04CM596MTR is a high-power LED driver and 4-bit shift register designed for Power-LED applications. It contains a 4-bit serial IN, parallel OUT shift register feeding a D-type storage register. The output stage features four regulated current sources providing 80 mA to 400 mA constant current. It guarantees 20 V output driving capability for series LED connections. The device supports a 30 MHz clock frequency and operates with a 3.3 V microcontroller interface. It includes UVLO, POR, and thermal shutdown protection. Operating temperature range is -40°C to +125°C. ESD protection is 2.5 kV HBM. It is available in TSSOP16 exposed pad package.
Feature Summary
- Four constant current output channels with adjustable current via one external resistor
- High-speed 30 MHz clock frequency supporting high volume data transmission
- Integrated thermal shutdown and under-voltage lockout for system reliability
- Compatible with 3.3 V logic levels for direct microcontroller interfacing
Applications
- Very high brightness displays
- Special lighting applications
- Power-LED panel systems
Procurement Notes
Verify the specific suffix 'MTR' indicates tape and reel packaging configuration as per official datasheet specifications. Confirm RoHS compliance status and lead-free ECOPACK2 package details directly from the manufacturer's documentation. Ensure the component designation matches the exact part number required for your design implementation.
Selection Notes
Select this component when designing circuits requiring precise constant current regulation for high-power LEDs. The 20 V output capability allows for flexible series LED configurations. Consider the TSSOP16 exposed pad package for optimal thermal performance in high-current applications. Verify that the 30 MHz clock speed meets the system's data transmission requirements.
Part Context
This part belongs to the STP04CM family of power LED drivers from STMicroelectronics. It shares functional similarities with other members like the STP04CM05 but may differ in packaging or specific electrical characteristics. The family is targeted at high-brightness display and specialized lighting markets requiring reliable constant current sinking.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Consult official STMicroelectronics documentation for potential cross-references or newer alternatives within the same product line.
