Overview
The STP16CP05PTR 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. The output stage provides sixteen regulated current sources delivering 5 mA to 100 mA constant current. It supports a 3 V to 5.5 V supply, 20 V output driving capability, and a 30 MHz max clock frequency. The device operates between -40°C and +125°C.
Feature Summary
- Provides sixteen constant current output channels with adjustable brightness via an external resistor.
- Supports high-speed data transmission with a maximum clock frequency of 30 MHz.
- Compatible with 3.3 V microcontrollers for direct interface applications.
- Includes ESD protection rated at 2 kV HBM and 200 V MM.
Applications
- LED panel displays
- High brightness LED arrays
- Low voltage LED sink driver circuits
Procurement Notes
Verify the package type matches the required SSOP-24 configuration for your PCB layout. Confirm that the operating temperature range of -40°C to +125°C meets your environmental specifications. Ensure the external resistor selection aligns with the desired 5 mA to 100 mA output current range for proper LED brightness control.
Selection Notes
Select this component when a 16-channel constant current sink is required for LED matrices. It is suitable for designs needing compatibility with 3.3 V logic levels. Consider the 20 V output capability if connecting multiple LEDs in series. Verify thermal management requirements given the industrial temperature range and power dissipation characteristics.
Part Context
This part belongs to the STP16CP05 series of low-voltage LED drivers from STMicroelectronics. It serves as a core component for driving LED panels where uniform current distribution across multiple channels is critical. The series offers variations in packaging and specific electrical ratings while maintaining the same functional architecture.
Replacement Considerations
STP16CPP05TTR: Offers similar functionality but with a different output current range (3 mA to 40 mA) and potentially different ESD protection levels. Verify pinout compatibility and current requirements before substitution.
