STP16DPP05MTR

Overview

The STP16DPP05MTR is a low-voltage, 16-bit LED sink driver manufactured by STMicroelectronics. It features a serial-in, parallel-out shift register with D-type storage and sixteen regulated constant current sources providing 3 to 40 mA per channel. The device supports output error detection for open and short circuits via the OE/DM2 pin. It operates on a 3V to 5.5V supply, includes a 30 MHz clock frequency, and offers PWM dimming from 0% to 100%. Packaged in a 24-SOP surface-mount format, it ensures high thermal efficiency and compatibility with 3.3V microcontrollers.

Feature Summary

• Integrated 16-bit constant current sink drivers with adjustable output current ranging from 3 to 40 mA via an external resistor.
• Built-in diagnostic circuitry detects open lines and short circuits (to ground or voltage) without increasing pin count.
• Supports high-speed data transmission with a 30 MHz clock frequency and 3.3V MCU interface capability.
• Enables full brightness control through pulse-width modulation dimming controlled by the output enable pin.

Applications

• LED panel displays requiring high data rate transmission
• Low voltage power supply systems interfacing with 3.3V microcontrollers
• Applications necessitating real-time output error detection for maintenance

Procurement Notes

Verify the package type matches the specific suffix; the MTR suffix indicates tape and reel packaging. Confirm the operating temperature range aligns with system requirements, typically spanning -40°C to +125°C. Ensure the design accommodates the required external resistor for current setting. Check moisture sensitivity levels and handling precautions during assembly to maintain component integrity.

Selection Notes

Select this component when integrated fault detection is critical for display reliability. It is suitable for designs requiring precise current regulation across multiple channels. Consider the thermal performance of the SOP package versus exposed pad variants if heat dissipation is a primary constraint. Verify that the 30 MHz clock speed meets the refresh rate requirements of the target application.

Part Context

This part belongs to the STP16DPP05 series, which focuses on low-voltage LED driving with diagnostic capabilities. It shares functional similarities with other STP16xx devices but distinguishes itself through specific error detection features and current ranges. The series is designed for modern display applications where space and power efficiency are prioritized alongside robust operational monitoring.

Replacement Considerations

STP16CPPS05XTTR serves as a parameter-equivalent alternative within the same manufacturer lineup. Both parts offer similar 16-bit architectures and current drive capabilities. Evaluate thermal management requirements and package dimensions before substitution to ensure mechanical fit and electrical compatibility.
