CL7

Supertex inc. CL7 Linear, 100mA, Constant Current LED Driver with Enable Input Features ►►100mA ±5% constant current drive ►►Built-in reverse polarity protection ►►Logic level enable ►►Dimmable via EN pin ►►Overtemperature protection ►►90V max rating for transient immunity Applications ►► Flashlights ►► Specialty lighting ►► Low voltage signage ►► Low voltage lighting General Description The CL7 is a linear fixed current regulator designed for driving high brightness LEDs at 100mA from nominal 12V, 24V, and 48V power supplies. With a maximum rating of 90V, it is able to withstand transients without the need for additional transient protection circuitry. The CL7 is offered in the 8-Lead SOIC 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 100kΩ pull-down resistance. For applications not needing an enable input, refer to the CL6 data sheet. Over temperature protection shuts off the LED current when the die temperature rises above 135°C (nominal). Full LED current resumes when the die temperature falls below 105°C (nominal).
