STMicroelectronics Introduces First Auto-Shutdown LED Driver to Address Energy-Saving Programs
| | |
| | | |||||||||||||||||
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. Operating over a wide temperature range of -40ºC to +125ºC, 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. Further information is available at www.st.com/powerlogic Click here for the high-resolution photo
