CAT4104 - 700mA Quad Channel Constant Current LED Driver

General Description

The CAT4104 provides four matched low dropout current sinks to drive high

brightness LED strings up to 175 mA per channel.

The LED channel current is set by an external resistor connected to the RSET pin.

700 mA Quad Channel Constant Current LED Driver CAT4104 Description The CAT4104 provides four matched low dropout current sinks to drive high−brightness LED strings up to 175 mA per channel. The LED channel current is set by an external resistor connected to the RSET pin. The LED pins are compatible with high voltage up to 25 V supporting applications with long strings of LEDs. The EN/PWM logic input supports the device enable and high frequency external Pulse Width Modulation (PWM) dimming control. Thermal shutdown protection is incorporated in the device to disable the LED outputs whenever the die temperature exceeds 150°C. The device is available in the 8−pad TDFN 2 mm x 3 mm package and the SOIC 8−Lead 150 mil wide package.
