STP16DPPS05MTR

Overview

The STP16DPPS05MTR is a low-voltage, 16-bit LED sink driver manufactured by STMicroelectronics. It integrates a serial-in, parallel-out shift register and a D-type storage register to drive LEDs with constant current ranging from 3 mA to 40 mA per channel. The device supports output error detection for open and short circuits without increasing pin count. It operates on a 3 V to 5.5 V supply, features a 30 MHz clock frequency, and includes auto power-saving modes. The component is housed in a 24-SOIC package.

Feature Summary

• Integrates 16-bit shift and storage registers for serial data processing
• Provides regulated constant current sources for LED intensity control
• Detects output line faults including shorts and open circuits
• Supports PWM dimming via the output enable pin

Applications

• LED panel displays
• Low voltage indicator systems
• High data rate transmission interfaces

Procurement Notes

Verify the specific suffix MTR against the official datasheet to confirm the tape and reel packaging configuration. Ensure the design accommodates the 24-SOIC footprint and thermal requirements. Confirm that the 3V to 5.5V supply range aligns with the system's MCU logic levels. Check for any recent production change notices regarding moisture sensitivity or assembly updates.

Selection Notes

Select this component when a 16-channel constant current sink is required with integrated fault detection. It is suitable for designs needing high-speed serial data input at 30 MHz. The exposed pad variant offers superior heat dissipation compared to standard packages. Verify compatibility with 3.3 V microcontrollers for direct interface without level shifting.

Part Context

This part belongs to the STP16DPxx series of LED display drivers. It shares functional similarities with other members like the STP16CPPS05 but differs in specific package options and detection capabilities. The series is designed for low-power applications requiring precise current regulation and diagnostic feedback for maintenance.

Replacement Considerations

Public confirmed substitutes include STP16CPPS05XTTR and STP16DPPS05XTTR. Verify package compatibility as these may use TSSOP-EP instead of SOIC.
