ST Saves Energy with Auto-Shutdown LED Driver

STMicroelectronics (NYSE: STM), a leader in ICs for driving high-brightness (HB) LEDs, 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.

STMicroelectronics STP16CPS05 LED driver with auto-power-savingAn 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.

Operating over a wide temperature range of -40°C to +125°C, the STP16CPS05 can work with a power supply from 3.3V up to 5V; its output current is programmable from 5mA to 80mA to suit applications requiring mid-current range and high-precision LED control.

In production now, the STP16CPS05 is $0.80 in quantities of 100,000 pieces.
