Overview
The STP16C596ATTR is a 16-bit constant current LED sink driver manufactured by STMicroelectronics. It operates within a supply voltage range of 3 V to 3.6 V and draws a maximum power supply current of 14.1 mA. The device provides regulated output currents of 1 mA for high-level states and -1 mA for low-level states. It supports both serial and parallel interface types and is housed in an SOIC-24 surface-mount package. The component functions reliably across an extended temperature range from -40 °C to +125 °C.
Feature Summary
- Integrates sixteen regulated constant current sources specifically designed for driving LED displays.
- Supports dual interface modes including serial data input and parallel data output configurations.
- Features robust operational stability across wide industrial temperature extremes.
Applications
- LED display panel systems requiring precise current regulation
- Low-voltage microcontroller interfacing for visual indicators
- Portable electronic devices utilizing surface-mount assembly
Procurement Notes
Verify component authenticity through authorized distribution channels due to potential availability constraints. Confirm specific ordering suffixes match required packaging and temperature grades. Review official datasheets for pinout compatibility and electrical limits before integration. Ensure compliance with RoHS directives relevant to the manufacturing batch. Validate end-of-life status implications for long-term production planning.
Selection Notes
Evaluate the 1 mA output current capability against specific LED forward current requirements. Consider the SOIC-24 package dimensions for PCB layout constraints. Assess thermal performance needs given the operating temperature range. Compare interface flexibility between serial and parallel modes for system architecture compatibility. Verify voltage tolerance matches the target logic supply levels.
Part Context
This component belongs to the STP16CL596 series of LED display drivers. It shares functional similarities with other members like the STP16DPS05, though it lacks advanced diagnostic features such as open/short detection. The series targets applications needing reliable constant current sinking in compact packages.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer resources for direct replacements or verify backward compatibility with similar series members like the STP16CL596.
