LED8102S Datasheet 8-channel LED driver with direct switch control Features 8 constant current output channels controlled by switch inputs Output enable input for global dimming Output current: from 5 mA to 100 mA HTSSOP16 (Exposed pad) Current programmable through external resistor Supply voltage: 3 V to 5.5 V Thermal shutdown 19 V current generators rated voltage Available in high thermal efficiency TSSOP exposed pad package ESD protection 2.0 kV HBM, 100 V MM Applications White and RGB lighting and Backlight Appliance display and human interface Industrial display and function indicator Architectural Lighting Description The LED8102S is a monolithic, low voltage, 8 low-side-channel LED driver. The LED8102S guarantees up to 19 V output driving capability allowing users to connect several LEDs in series. In the output stage, 8 regulated current sources provide from Maturity status link 5 mA to 100 mA constant current to drive the LEDs. Current is programmed through LED8102S a single external resistor. LED8102S is equipped with a thermal management that protects the device forcing Device summary it in shutdown (typically: power-off at 170 C with 15 C hysteresis to restart). The Order code LED8102SXTTR thermal protection switches OFF only the output channels. Package HTSSOP16 The operative supply voltage range is between 3 V and 5.5 V. The output control is provided by four switch inputs, providing an on/off toggle action suitable also for Packing 2500 parts per reel local dimming. Moreover, on all active output LEDs brightness can be adjusted with a global PWM signal applied to the output enable pin (OE). Outputs can be connected in parallel, or left unconnected if not used, as required by the application.
