1. Add “-T* suffix for tape and reel. Please 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.

DESCRIPTION
Fault Disconnect Switch Gate Control.
Input voltage for the device and LED power.
Enable input. The device needs 4ms for initial power-up enable. It will be disabled if it is not biased for longer than
30.5ms.

I/O
Internal LDO output. Connect a decoupling capacitor to ground.
PWM brightness control pin or DPST control input.
SMBus/I 2 C 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.
SMBCLK/SCL
7
I
SMBus/I 2 C 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.
FPWM
8
I
Set PWM dimming frequency, by connecting a resistor between this pin and ground. When FPWM is tied to VDC and
SMBCLK/SMBDAT is tied to ground, the device will be in Direct PWM Dimming where the output follows the input
frequency and duty cycle without any digitization.

Analog Ground for precision circuits.
Current source and channel monitoring input for channels 0-5.
Overvoltage protection input.
Resistor connection for setting LED current, (see Equation 1 for calculating the I LED(peak) ).
Boost compensation pin.
Power ground
Boost switch node.
No electrical connection but should be used to connect PGND and AGND. For example use top plane as PGND and
bottom plane as AGND with vias on EPAD to allow heat dissipation and minimum noise coupling from PGND to
AGND operation.
