STMicroelectronics Introduces First Auto-Shutdown LED Driver to Address Energy-Saving Programs

STMicroelectronics (NYSE: STM), a leader in ICs for driving high-brightness (HB) LEDs has introduced the first LED driver to include auto-power-saving features. The STP16CPS05, an innovative member of ST’s Power Logic family, allows manufacturers to meet the high power-efficiency requirements of industrial lighting, signage and transport applications by guaranteeing savings of 80% compared to existing solutions.

An evolutionary advantage over the previous STP16Cx596 Power Logic series, the new constant-current LED drivers allow the individual ICs to go into a shutdown mode when no active inputs are detected. As a result, the STP16CPS05 can save power without external intervention, making it the ideal solution to support all worldwide energy-saving programs which encourage power efficiency in lighting applications.

The STP16CPS05 Power Logic series features a clock and data re-synchronization function, which is useful when the devices are connected in cascade. The IC is available in four package types, of which one, the thermally efficient exposed-pad TSSOP, comes with outstanding heat dissipation features.
