Highly Flexible, Small High-Power LED Driver Can Drive Up to 8 HB LEDs for Displays and Electronics in Automotive

MILPITAS, CA, Apr 10 (MARKET WIRE) --
Intersil Corporation (NASDAQ: ISIL), a world leader in the design and
manufacture of high-performance analog semiconductors, today announced the
release of the
ISL78100, a High Power Integrated LED Driver designed for display backlighting
and body electronics applications. The ISL78100 is designed specifically to
withstand harsh automotive environments.

The ISL78100 is very flexible and can be configured to optimally drive
fromone to eight HB (high brightness) LEDs, while being capable of operating
inboost, buck or SEPIC configurations. The ISL78100 also features two
methodsof controlling LED light level; a DC bias current, or through the use of
anexternal PWM signal for more accurate control of the LED color
temperature.

In addition, there are optional integrated protection features that the
designer can choose from with the ISL78100. An available fault monitor
thatdisconnects the input supply can be used to protect against load dump
conditions.

The ISL78100 also features thermal compensation and a load isolation switch.
The
device's temperature compensation drastically improves LED lifespan and an
integrated over-temperature control circuit monitors a thermistor voltage
and adjusts the LED bias current. This high level of integration allows
designers to avoid the use of costly discrete protection solutions.

The ISL78100 is up to 92 percent efficient and thus will extend battery life
in
applications when the vehicle's ignition is off.

The device is both AEC-Q100-rated and fully TS16949-compliant, including a
higher process CPK. The ISL78100 is rated for the automotive temperature range
(-40
degrees C to +105 degrees C) and, with a tiny 4mm x 4mm x 0.9mm QFN
package,is the smallest integrated high power LED driver available.

Pricing and Availability

The ISL78100 is available now in a 20-lead QFN package and is priced at
$1.32 in 1,000-unit quantities and at $1.39 in 1,000-unit quantities in
tape-and-reel configurations. More information on the ISL78100 is
availableat to editors: To view a high-resolution downloadable photo of the
