STP16C596M

Overview

The STP16C596M 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 package designed for surface mount installation. The component functions reliably across an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Provides sixteen regulated constant current channels specifically designed for driving LED displays
• Integrates serial-in, parallel-out shift register architecture with D-type storage capabilities
• Supports backward compatibility with the STP16C/L596 family for simplified design transitions

Applications

• LED panel display systems requiring constant current sinking
• Low-voltage microcontroller interfacing applications
• High data rate transmission environments utilizing serial interfaces

Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm the specific suffix 'M' corresponds to the required SOIC-24 packaging variant. Check for end-of-life status as indicated by availability records. Ensure environmental compliance documentation matches project requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring precise 1 mA constant current regulation for LED segments. Consider the SOIC-24 package constraints regarding board space and thermal dissipation. Evaluate the -40 °C to +125 °C operating range against environmental conditions. Verify that the 3 V to 3.6 V supply voltage aligns with the system's power architecture.

Part Context

This part belongs to the STP16CL596 series of LED display drivers. It serves as a specialized interface between digital logic and LED arrays, ensuring uniform brightness through constant current control. The series is engineered for low-power applications compatible with standard 3.3 V logic levels.

Replacement Considerations

The STP16DP05 and STAP16DPS05 are documented as backward compatible replacements. These alternatives offer similar functionality but may include additional features such as open and short circuit detection capabilities.
