NOTES:

1. Add “-T” suffix for 6k unit or “-TK” for 1k unit tape and reel options.

Refer to TB347 for details on reel specifications.

2. These Intersil Pb-free plastic packaged products employ special

Pb-free material sets, molding compounds/die attach materials, and

100% matte tin plate plus anneal (e3 termination finish, which is

RoHS compliant and compatible with both SnPb and Pb-free

soldering operations). Intersil Pb-free products are MSL classified at

Pb-free peak reflow temperatures that meet or exceed the Pb-free

requirements of IPC/JEDEC J STD-020.

3. For Moisture Sensitivity Level (MSL), please see the product

information page for ISL97671. For more information on MSL, refer

to TB363.

DESCRIPTION

O Fault disconnect switch.

S Input voltage for the device and LED power.

I The device needs 4ms for initial power-up enable. It will be disabled if it is not biased for longer than 28ms.

S De-couple capacitor for internally generated supply rail.

I PWM brightness control pin or DPST control input.

I/O SMBus/I2C serial data input and output. When pins 6 and 7 are grounded or in logic 0’s for longer than 60ms, the

drivers will be controlled by external PWM signal.

I SMBus/I2C serial clock input. When pins 6 and 7 are grounded or in logic 0’s for longer than 60ms, the drivers will

be controlled by external PWM signal.

I Set PWM dimming frequency, FPWM by connecting a resistor. See the “PWM Dimming Frequency Adjustment”

section for resistor calculation.

S Analog Ground for precision circuits.

I Input 0 to current source, FB, and monitoring.

I Input 1 to current source, FB, and monitoring.

I Input 2 to current source, FB, and monitoring.

I Input 3 to current source, FB, and monitoring.

I Input 4 to current source, FB, and monitoring.

I Input 5 to current source, FB, and monitoring.

I Overvoltage protection input.

I Resistor connection for setting LED current, (see Equation 2 for calculating the ILED(peak)).

O Boost compensation pin.

S Power ground

O Input to boost switch.
