PIN FUNCTION

is the supply pin. The operating input voltage

range is from 2.5 V to 5.5 V.

EN is the enable input for the entire device.

Guaranteed levels of logic high and logic low are set

at 1.3 V and 0.4V respectively. When EN is initially

taken high, the device becomes enabled and may

communicate through I

C interface

SDAT is the I

C serial data line. This is a bidirectional

line allowing data to be written into and read from

internal registers.

SCLK is the I

C serial clock input.

SADD is I

C Serial interface Addresses tie to either

GND or VIN pin to allow choice of two slave

addresses. Allows two 9003 or 9001 on same control

bus for optional increased LED-SenseTM point

monitoring control

GND is the ground reference for internal circuitry.

The pin must be connected to the ground plane on

the PCB.

TSENSE1, TSENSE2, TSENSE3 (LDS9003) and

TSENSE (LDS9001) are the LED-Sense

temperature sensing pins for the LEDs. These

connect to the LED anodes. These pins force

currents of 1mA and 200ua and measure voltages for

calculation of LED junction temperature. These pins

enter high-impedance zero current state whenever

the device is in shutdown mode.

IPWM1, IPWM2, IMPWM3 (LDS9003) and IPWM

(LDS9001) are the PWM 1mA peak to GND current

sources outputs for controlling PWM of external HB

LED driver. User adds resistor to GND to generate

desired PWM voltage range levels. These pins enter

high-impedance zero current state whenever the

device is in shutdown mode.

TST is a test pin used by factory only. Leave it

floating (no external connection)

PAD is the exposed pad underneath the package.

For best thermal performance, the tab should be

soldered to the PCB and connected to the ground

plane
