Overview

The STP16CPC26MTR is a 16-channel constant current sink LED driver featuring a built-in oscillator and a 30MHz SPI-compatible shift register interface. It is designed to drive LEDs with up to 90mA per channel while maintaining high output current accuracy within 1 percent between channels.

Why Choose This Part

The device features 16 constant current outputs that can be globally adjusted using a single external resistor, providing high brightness uniformity across all channels. It includes integrated thermal shutdown protection and a high-speed serial interface to support high refresh rates without straining the host microcontroller.

Applications

LED Signs and Displays
High-density 16-channel control allows for driving segmented displays or LED matrices with minimal external components.
Industrial Status Indicators
Reliable constant current sinking for multi-LED panels in industrial equipment requiring thermal protection.
Backlighting
Consistent current matching ensures uniform brightness across large panels or decorative lighting strips.

Getting Started

Engineers can begin evaluation by connecting the SPI interface to a microcontroller and setting the maximum output current via a resistor on the R-EXT pin. For rapid prototyping, look for STMicroelectronics STEVAL evaluation boards or similar break-out modules designed for the STP16 series of drivers.
