STMicroelectronics has introduced a set of single-chip LED driver ICs for industrial lighting, signage and transport applications. The Power Logic STPxxC596 and STPxxCL596 family integrates the functions needed to drive LEDs at a constant current, set by an external resistor. Once set, a feedback mechanism monitors the current in one LED or a string of LEDs and dynamically adjusts the output to maintain the programmed current level.
The output current is programmable from 15 mA up to 120 mA (with a 5 V supply). The devices can work with power supply from 3,3 V up to 5 V, which means they can be directly controlled by a microprocessor or logic circuit without level translators.
The STP08C596 has eight output channels, each of which can provide 15 to 120 mA constant current to drive the LEDs - available in DIP-16, SO-16 and TSSOP16.
The STP08CL596 has eight output channels, each of which can provide 15 to 90 mA constant current. It runs from a 3,3 V supply and is available in DIP-16 and SO-16.
The STP16C596 has 16 output channels, each of which can provide 15 to 120 mA constant current - available in DIP-24, SO-24, TSSOP24 and the thermally efficient exposed-pad TSSOP24.
The STP16CL596 has 16 output channels, each of which can provide 15 to 90 mA constant current. It runs from a 3,3 V supply and is available in DIP-24, SO-24, TSSOP24 and the thermally efficient exposed-pad TSSOP-24.
The parts accept serial data through SPI bus and use an internal shift register and latches to set the data for each of the LED outputs. An output enable controller can switch each LED on or off, dim it or make it flash. The parts have a clock and data re-synchronisation function, which is useful when the devices are cascaded.
