Overview
The STP04CM596B1R is a monolithic LED driver IC manufactured by STMicroelectronics, designed for high-power LED applications. It features a linear shift register topology with four constant current output channels, each capable of sourcing up to 500mA. The device operates within a supply voltage range of 3.3V to 5.5V and supports an output voltage of up to 19V. It utilizes a 14-DIP package for through-hole mounting and functions reliably across a temperature range of -40°C to 125°C.
Feature Summary
- Linear shift register topology enables precise dimming control
- Four independent output channels with internal switching capability
- Designed specifically for power-LED applications
Applications
- High-power LED lighting systems
- LED panel displays
- General illumination circuits requiring constant current drive
Procurement Notes
Verify the specific suffix B1R against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the procurement source provides authentic documentation from STMicroelectronics. Confirm that the 14-DIP package matches the target PCB footprint requirements before finalizing orders.
Selection Notes
Select this component when a linear shift register interface is required for LED dimming. It is suitable for designs needing four independent constant current outputs with moderate current levels. Consider the 14-DIP package constraint for through-hole assembly processes. Evaluate thermal management needs given the linear regulation method and operating temperature range.
Part Context
This part belongs to the STP04CM series of LED drivers from STMicroelectronics. It shares functional similarities with other members like the STP04CM05 but differs in output current capabilities. The series is characterized by its integration of shift register logic with power output stages, simplifying control interfaces for multi-channel LED arrays.
Replacement Considerations
Check for direct substitutes within the STP04CM family or equivalent devices from other manufacturers offering similar 4-channel linear shift register architectures. Verify pin-to-pin compatibility and ensure output current ratings meet or exceed the 500mA requirement.
