Overview
The STP16CP05XTTR is a monolithic, low-voltage, low-current power 16-bit shift register 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 5 mA to 100 mA constant current. The device supports a supply voltage from 3 V to 5.5 V and guarantees a 20 V output driving capability. It operates at a maximum clock frequency of 30 MHz and includes ESD protection rated at 2 kV HBM and 200 V MM.
Feature Summary
- Provides sixteen constant current output channels for direct LED driving
- Adjustable output current via external resistor for brightness control
- Supports high-speed data transmission with a 30 MHz max clock frequency
- Includes integrated ESD protection for enhanced reliability
Applications
- LED panel displays
- High data rate transmission systems
- Applications interfacing with 3.3 V microcontrollers
Procurement Notes
Verify the specific package variant against official datasheets, as suffixes indicate tape and reel packaging. Confirm RoHS compliance status and ECOPACK2 environmental standards prior to integration. Ensure input voltage ranges align with system requirements to prevent operational faults during procurement validation.
Selection Notes
Select this component when designing LED panels requiring precise constant current regulation across multiple channels. It is suitable for systems needing compatibility with 3.3 V logic levels and high-speed serial data interfaces. Consider the thermal performance and output voltage headroom for series-connected LED configurations.
Part Context
This part belongs to the STP16CP05 series of low-voltage LED sink drivers manufactured by STMicroelectronics. It is functionally similar to other members like the STP16CPC05 but may differ in specific packaging or minor electrical characteristics. The series is engineered for efficient LED display control with minimal external components.
Replacement Considerations
The STP16DP05 offers similar functionality but adds short and open output error detection capabilities. For automotive applications, the STAP16DPPS05 provides AEC-Q100 qualification and auto power-saving features. Verify pinout and electrical specifications before substituting.
