STP08DP05MTR

Overview

The STP08DP05MTR is a low-voltage, low-current power 8-bit shift register designed for LED panel displays. It features a serial-in, parallel-out shift register feeding an 8-bit D-type storage register. The output stage provides eight regulated current sources delivering 5-100 mA constant current to drive LEDs. It supports a 20 V output driving capability and operates with a supply voltage range of 3 V to 5.5 V. The device includes open and short detection on outputs via the OE/DM2 pin and achieves high clock frequencies up to 30 MHz.

Feature Summary

• Integrated error detection circuitry identifies short-to-ground, short-to-Vo, and open line conditions without increasing pin count
• Adjustable output current controlled by an external resistor allows precise light intensity management
• Supports PWM dimming from 0% to 100% brightness via the OE/DM2 pin
• High-speed data transmission capability with a maximum clock frequency of 30 MHz

Applications

• LED panel displays
• Low-voltage microcontroller interfacing systems
• Applications requiring integrated output fault detection

Procurement Notes

Verify the specific suffix MTR indicates cut-tape packaging when sourcing. Confirm the operating temperature range covers -40°C to +125°C for your environment. Ensure the 3 V to 5.5 V supply voltage aligns with your system design. Check RoHS compliance status through official manufacturer documentation before integration.

Selection Notes

Select this component when 8-bit constant current sinking with diagnostic feedback is required. It serves as a functional replacement for STP8C/L596 with added detection capabilities. Consider the TSSOP package thermal performance if heat dissipation is critical. Verify interface compatibility with 3.3 V logic levels for seamless microcontroller integration.

Part Context

This part belongs to the STP08DP05 series of monolithic LED drivers. It extends standard shift register functionality by incorporating comprehensive output error detection. The design targets applications needing reliable LED control with minimal pin usage. It maintains backward compatibility with previous generations while offering enhanced diagnostic features.

Replacement Considerations

The STP08DP05 is functionally and footprint compatible with the STP8C/L596. Verify that the additional detection logic does not conflict with existing control sequences. Ensure the 20 V output rating meets the series LED voltage requirements of the target application.

FAQ

How is output error detection activated?

Detection mode is entered or exited through a dedicated logic sequence using the output enable and latch pins (OE/DM2).

What types of output faults can be detected?

The device detects short-to-ground, short-to-Vo, and open line conditions on the output lines.

Can the LED brightness be adjusted digitally?

Yes, brightness intensity can be adjusted from 0% to 100% via the OE/DM2 pin.
