CAT4004
4-Channel Constant Current
LED Driver with EZDim t
Description
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).
The device is available in a tiny 8 ? lead TDFN 2 mm x 3 mm
