Overview
The STP16CP596TTR is a monolithic, medium-voltage, low-current power 16-bit shift register designed for LED panel displays. It features constant current output with 50mA per channel and operates within a supply voltage range of 3V to 5.5V. The device provides a maximum output voltage of 20V and supports a clock frequency up to 25MHz. Packaged in a 24-TSSOP surface-mount format, it integrates internal drivers for direct LED control.
Feature Summary
- Integrates 16-bit shift register functionality with constant current sink outputs for uniform LED brightness
- Supports high-speed serial data input with clock frequencies up to 25MHz
- Features medium-voltage capability allowing direct connection to LED strings without external level shifting
Applications
- LED panel displays
- Dot matrix display modules
- Low-power indicator arrays
Procurement Notes
Verify the specific suffix 'TTR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the 24-TSSOP footprint matches the target PCB layout dimensions. Ensure the operating temperature range specified in the official datasheet aligns with the environmental conditions of the final application to guarantee long-term reliability.
Selection Notes
Select this component when a 16-channel constant current solution is required for low-to-medium density LED matrices. The 50mA output rating suits standard indicator LEDs but may be insufficient for high-power applications requiring higher current sinks. Consider the 25MHz speed limit if system timing constraints exceed this frequency threshold.
Part Context
This part belongs to the STP16Cxx series of LED driver ICs from STMicroelectronics. These devices are engineered specifically for driving LED panels where space efficiency and low power consumption are critical. The series typically offers varying current ratings and voltage capabilities to accommodate different LED configurations and display densities.
Replacement Considerations
Consult official substitution lists for compatible parts within the STP16Cxx family or equivalent 16-bit shift register drivers from other manufacturers. Verify pin compatibility and electrical specifications before swapping components to ensure circuit integrity.
