CAT4004AHU2-GT3
LED Driver, 4-Channel, with 32 Dimming Levels and Reset ONSSPCAPLFRS;
-
RoHS 10 Compliant -
Tariff Charges
The CAT4004 provides four matched low dropout current sources to drive LEDs. An external resistor on RSET sets the current in the LED channels. Each LED channel includes an individual control loop allowing the device to handle a wide range of LED forward voltages while still maintaining tight current matching.The EN/DIM logic inputs supports device enable and a digital dimming interface for current setting of all LEDs. Six different current dimming ratios are available.The device is aimed at 'direct drive' battery applications. It is required that the battery or voltage source have enough headroom to drive the LED forward voltage and current sink (>150 mV).
- Four LED current sinks with tight matching
- Low Dropout Driver 130 mV at 30 mA
- No switching noise
- Shutdown current < 1µA
- LED current set by external resistor
- Dimming via 1-wire EZDim™ interface
- Thermal shutdown protection
