Overview
The STP16DPP05PTR is a monolithic, low-voltage, 16-bit constant current LED sink driver designed for LED panel displays. It features a serial-in, parallel-out shift register feeding a D-type storage register with sixteen regulated current sources providing 3 to 40 mA per channel. The device supports open and short LED detection via the OE/DM2 pin without increasing pin count. It operates on a 3 V to 5.5 V supply, interfaces directly with 3.3 V MCUs, and utilizes a high 30 MHz clock frequency. The TSSOP-24 exposed pad package enhances thermal dissipation.
Feature Summary
- Integrated output error detection for open and short circuits
- Adjustable constant current output via external resistor
- High-speed 30 MHz serial data transmission capability
- Enhanced thermal efficiency through exposed pad packaging
Applications
- LED panel displays
- Low voltage indicator systems
- Microcontroller-driven lighting control
Procurement Notes
Verify the specific suffix PTR against official STMicroelectronics documentation to confirm the exact tape and reel quantity and packaging configuration. Ensure compatibility with the required operating temperature range of -40°C to +125°C. Confirm that the 24-TSSOP-EP package dimensions match the target PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when designing systems requiring integrated fault detection alongside standard LED driving functions. The exposed pad package is suitable for applications where thermal management is critical within a compact surface-mount footprint. Ensure the design accommodates the external resistor needed for current setting and the logic sequence required to toggle between normal operation and detection modes.
Part Context
This part belongs to the STP16DP05 series of low-voltage LED drivers from STMicroelectronics. It shares functional similarities with other members like the STP16CPP05 but distinguishes itself through the inclusion of dedicated output error detection capabilities. The series is engineered for reliable performance in display applications requiring precise current regulation and diagnostic feedback.
Replacement Considerations
Publicly confirmed substitute part numbers include STP16CPPS05XTTR and STP16DPPS05XTTR. Verify electrical parameter equivalence and package compatibility before substitution.
