CL7 100 mA Constant-Current Linear LED Driver with Enable Input Features General Description 100 mA 5% Constant-current Driver The CL7 is a fixed-current linear regulator designed for driving high-brightness LEDs at 100 mA from nominal Built-in Reverse Polarity Protection 12V, 24V and 48V power supplies. With a maximum Logic-level Enable rating of 90V, it is able to withstand transients without Dimmable via EN Pin the need for additional transient protection circuitry. Overtemperature Protection The CL7 is offered in the 8-lead SOIC (with heat slug) 90V Maximum Rating for Transient Immunity package. An active-low enable input (EN) allows logic-level control of the LED for on/off control or PWM dimming. The enable input has 100 k pull-down resistance. For Applications applications not needing an enable input, refer to the Flashlights CL6 data sheet. Specialty Lighting Overtemperature protection circuitry shuts down all Low-voltage Signage three channels when the nominal die temperature Low-voltage Lighting reaches 135C. Normal operation resumes when the die temperature falls below 105 C.
