STP16DPPS05PTR

Overview

The STP16DPPS05PTR is a monolithic, low-voltage LED display driver featuring a 16-bit serial-in, parallel-out shift register and storage register. It provides sixteen regulated constant current sources capable of delivering 3 to 40 mA per channel. The device supports open and short LED detection on outputs without increasing pin count, utilizing the OE/DM2 and DM1 pins for diagnostic data shifting. It guarantees a 20 V output driving capability and operates with a high 30 MHz clock frequency. The part is housed in a 24-SOP package.

Feature Summary

• Integrates sixteen constant current sink channels for direct LED panel drive
• Includes built-in circuitry for detecting open lines and shorts to ground or voltage supply
• Supports automatic power-saving shutdown and power-on sequences without external intervention
• Enables brightness adjustment from zero to one hundred percent via the output enable pin

Applications

• Traffic road signs and highway information displays
• Light box advertising panels and static signage
• Sports stadium large-scale screen displays
• Battery or solar-powered portable display equipment

Procurement Notes

Verify component status carefully as this specific suffix variant may be discontinued or restricted. Confirm availability through official STMicroelectronics channels rather than third-party distributors. Ensure the ordering suffix matches the required package type and moisture sensitivity level. Cross-reference the manufacturer part number against the latest datasheet revision to confirm functional equivalence before procurement.

Selection Notes

Select this component when designing systems requiring integrated error detection alongside standard LED driving functions. The exposed pad TSSOP variant offers superior thermal dissipation compared to standard packages. Consider the 30 MHz clock speed for high-data-rate applications. Verify that the 3V to 5.5V supply range aligns with the microcontroller interface voltage requirements.
