STP16DP05MTR

Overview

The STP16DP05MTR is a monolithic, low-voltage, 16-bit constant current LED sink driver designed for LED panel displays. It integrates a serial-in, parallel-out shift register and a D-type storage register to drive sixteen regulated current sources providing 5-100 mA per channel. The device supports a supply voltage range of 3 V to 5.5 V and offers a 20 V output driving capability. Key electrical parameters include a maximum power supply current of 14.5 mA, a clock frequency of 30 MHz, and an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Integrates open and short circuit detection capabilities on output lines without increasing pin count.
• Supports high-speed data transmission with a 30 MHz clock frequency suitable for high data rates.
• Enables precise LED brightness control from 0% to 100% via the OE/DM2 pin.
• Features an exposed pad in TSSOP packages to enhance heat dissipation efficiency.

Applications

• LED panel displays
• High data rate transmission systems
• 3.3 V microcontroller interfacing

Procurement Notes

Verify the specific suffix 'MTR' corresponds to the required tape and reel packaging configuration. Confirm that the SOIC-24 or TSSOP-24 package variant matches the PCB footprint requirements. Ensure the component meets ECOPACK environmental standards if applicable to the target market regulations.

Selection Notes

Select this component when error detection for open and short circuits is required alongside standard LED driving functions. It is suitable for designs needing backward compatibility with STP16C/L596 series devices. Consider the exposed pad thermal performance benefits when choosing between SOIC and TSSOP packages for high-density applications.

Part Context

This part belongs to the STP16DP05 series of low-voltage LED drivers. It is functionally similar to the STP16CP05 but includes additional diagnostic features. The MTR suffix indicates a specific manufacturing and packaging run within the active product line.

FAQ

How is the output error detection functionality implemented?

Detection is implemented through a secondary function of the output enable and latch pins (DM1 and DM2) using a dedicated logic sequence to enter or exit detection mode.

What conditions does the detection circuit check?

The circuit checks for three conditions: short to GND, short to VO, and open line on the output.
