ST's Auto-Shutdown LED Driver Supports Energy Saving Program

Introduction: ST introduced the first LED driver chip with automatic energy saving features. The STP16CPS05 is an innovative product in the ST power logic family that helps manufacturers meet the energy efficiency requirements of industrial lighting, corporate signage and transportation applications, ensuring 80% energy savings over existing solutions.

Compared to the previous STP16Cx596 series of power logic devices, the new constant current LED driver allows a single IC to enter shutdown mode when no active input signal is detected. As a result, the STP16CPS05 saves energy without external intervention and is the ideal solution for a global energy saving program that encourages the use of lighting.

The STP16CPS05 family of power logic products features a clock data resynchronization feature that is useful when LED drivers are connected in series. The IC is available in four packages, where the exposed TSSOP package has excellent thermal efficiency and excellent thermal performance.

Operating temperature range -40oC to +125oC, supply voltage 3.3V to 5V; output current adjustment range 5mA to 80mA, the new product is suitable for lighting applications requiring medium-intensity current and high-precision LED control.
