FUNCTION
LED String 1 Linear Current Source Output. DL1 drives the gate of the external FET on LED String 1 and has
approximately 15mA source/sink capability. Connect a minimum capacitor of 4700pF from DL1 to GND to
compensate the internal transconductance amplifier as well as program the rise and fall times of the LED currents.
LED String 1 External FET Drain Voltage Sense. The internal ADC uses this input to measure the drain to GND
voltage of the current sink FET. Drain voltage measurement information can be read back from the I 2 C
interface. Connect a voltage-divider to scale drain voltage as necessary.
LED String 2 Current-Sense Input. CS2 is regulated to a value set by an internal register. The regulation voltage
can be set between 97mV and 316mV.
LED String 2 Linear Current Source Output. DL2 drives the gate of the external FET on LED String 2 and has
approximately 15mA source/sink capability. Connect a minimum capacitor of 4700pF from DL2 to GND to
compensate the internal transconductance amplifier, as well as program the rise and fall times of the LED
currents.
LED String 2 External FET Drain Voltage Sense. The internal ADC uses this input to measure the drain to GND
voltage of the current sink FET. Drain voltage measurement information can be read back from the I 2 C
interface. Connect a voltage-divider to scale drain voltage as necessary.
LED String 3 Current-Sense Input. CS3 is regulated to a value set by an internal register. The regulation voltage
can be set between 97mV and 316mV.
LED String 3 Linear Current Source Output. DL3 drives the gate of the external FET on LED String 3 and has
approximately 15mA source/sink capability. Connect a minimum capacitor of 4700pF from DL3 to GND to
compensate the internal transconductance amplifier, as well as program the rise and fall times of the LED currents.
LED String 3 External FET Drain Voltage Sense. The internal ADC uses this input to measure the drain to GND
voltage of the current sink FET. Drain voltage measurement information can be read back from the I 2 C
interface. Connect a voltage-divider to scale drain voltage as necessary.
LED String 4 Current-Sense Input. CS4 is regulated to a value set by an internal register. The regulation voltage
can be set between 97mV and 316mV.
LED String 4 Linear Current Source Output. DL3 drives the gate of the external FET on LED String 4 and has
approximately 15mA source/sink capability. Connect a minimum capacitor of 4700pF from DL4 to GND to
compensate the internal transconductance amplifier, as well as program the rise and fall times of the LED currents.
LED String 4 External FET Drain Voltage Sense. The internal ADC uses this input to measure the drain to GND
voltage of the current sink FET. Drain voltage measurement information can be read back from the I 2 C
interface. Connect a voltage-divider to scale drain voltage as necessary.
Power Supply. IN is internally connected to a 26V shunt regulator that sinks current. In conjunction with an
external resistor it allows time-limited load dump events as high as 40V to be safely handled by the IC. Bypass
IN to GND with a minimum 10μF capacitor.
Current-Sense Input
Gate Driver Regulator Output. Bypass V CC to GND with a minimum 4.7μF ceramic capacitor. Gate drive current
pulses come from the capacitor connected to V CC . Place the capacitor as close as possible to V CC . If IN is
powered by a voltage less than 5.5V, connect V CC directly to IN.
Switching Regulator Gate Driver Output
Exposed Pad. Connect the exposed pad to the ground plane for heatsinking. Do not use this pad as the only
ground connection to the IC.
