Intersil Introduces Hybrid and Electric Vehicle (HEV/EV) Li-Ion Battery
Management Control Solution
ISO26262 Compliant ISL78600 Maximizes Vehicle Range and Battery Life

MILPITAS, CA, Nov 01, 2010 (MARKETWIRE via COMTEX) -- Intersil Corporation
/quotes/comstock/15*!isil/quotes/nls/isil (ISIL 12.90, -0.06, -0.43%) today
introduced its HEV/EV system solution, featuring an automotive grade Li-Ion
battery management system and safety monitor. Building upon Intersil's
history of providing superior battery management devices for the portable
electronics market, the automotive grade (AEC-Q100) ISL78600 multi-cell
solution is specifically designed and tested to address the safety,
reliability and performance requirements of the hybrid, plug-in hybrid
(PHEV) and electric vehicle markets.

To address the stringent safety requirements of the automotive market,
Intersil's HEV/EV solution provides customers with ISO26262 (ASIL)
compliance to prevent battery pack failures. The solution also provides
built-in fault detection for all of its major internal functions and detects
external faults such as open wire, over and under voltage as well as
temperature and cell balancing faults.

The ISL78600 battery management system provides the high accuracy needed for
precise state-of-charge measurements to extend vehicle driving range and the
life of high performance Li-Ion batteries. To accomplish this, each ISL78600
device utilizes a 14-bit temperature compensated data converter that scans
12 channels in less than 250 microseconds. Average mid-size HEV vehicles
today utilize 126 to 168 cells, which can be addressed with 11 to 14
ISL78600s per vehicle. When combined with four external temperature sensors,
the ISL78600 provides superior accuracy for state-of-charge measurements
across the full battery operating temperature range.

To achieve the highest possible reliability for intra-system communication,
the ISL78600 utilizes a high noise immunity and transient tolerant
communication scheme. This fully differential daisy-chain architecture
allows the use of low cost twisted pair wiring to stack multiple battery
packs together while protecting against hot plugging and high voltage
transients. The benefits offered by the Intersil HEV/EV system solution can
significantly reduce overall battery management system costs.

The ISL78600 allows for easy connection to microcontrollers via either a
2.5MHz SPI or 400KHz I2C interface, and is specified for -40oC to 105oC
operation. Moreover, while targeted at the HEV/EV market, the Intersil
solution can easily be adapted to address industrial and battery back-up
applications.

The ISL78601 Safety Monitor Also available today is Intersil's ISL78601
multi-cell battery monitor. Addressing the safety requirements of an HEV/EV
battery system, the ISL78601 device provides for standalone or independent
redundant fault monitoring. See the related news release, also issued today.

Pricing and Availability The ISL78600 is available now in a 10mm x 10mm
64-lead TQFP package. Pricing starts at $6.50 each in 10,000-piece
quantities. For additional information please visit
