Battery Charger Extends Backup Battery Life of Automotive
Intersil Corporation announces the ISL78693, a 3.6V single-cell battery charger
that extends the life of Lithium Iron Phosphate (LiFePO4) batteries used in
automotive emergency call (eCall) systems. The ISL78693 battery charger
offers up to 4x lower leakage current (3uA) than competitive chargers, allowing
the eCall backup battery to remain charged for a longer period of time.
Automakers worldwide are installing eCall in their Vehicle to Infrastructure
(V2I) systems. In the event of a crash, the eCall system automatically
broadcasts its location via GPS and contacts the nearest 24-hour emergency call
center for help. Thus, V2I eCall systems must be capable of operating reliably and autonomously from the backup battery
at a moment’s notice, even if the vehicle is involved in an accident minutes after being parked for several months.
Innovative Features Added Onto
HIPPEROS S.A. has added a series of
innovative features, including hardware
acceleration, fast multicore IPC, and mixed
criticality scheduling to its HIPPEROS
multicore real-time operating system (RTOS)
for high-performance embedded systems. The
new features are released in HIPPEROS version
HIPPEROS RTOS is a family of ITAR-free,
highly configurable, modular, and parallel
real-time operating systems (RTOS) designed
specifically for multicore platforms for the next
generation of reliable, low-power, hard real-time, high-performance embedded systems.
HIPPEROS’ modularity and configurability
enables different kernels to be tailored so
specific applications requirements can be
satisfied, while adapting to different use cases.
MOSFET Gate Driver Optimized for 62mm Modules
AgileSwitch LLC introduces the 62EM (62mm Electrical Master) silicon carbide (SiC) MOSFET gate driver series. The
easy-to-use, plug-and-play driver is compatible with most 62mm SiC MOSFET modules. Applications including heavy-duty traction vehicles; auxiliary power units in trains, buses, and trolleys; induction heating systems; and other high-power
industrial systems are rapidly moving from IGBTs to SiC power devices. The 62EM Series is designed specifically to
facilitate this conversion.
The 62EM driver incorporates AgileSwitch’s patented, software configurable Augmented Turn-Off (ATOff™)
technology. ATOff addresses two significant impediments to the successful
implementation of silicon carbide modules in high-power applications. By reducing
turn-off spikes and ringing, both under normal operation as well as short-circuit
(DSAT) conditions, SiC MOSFET modules can be safely operated in the higher
frequencies that enable dramatic increases in power conversion density. This allows
SiC MOSFET modules to be operated closer to their rated specifications, resulting
in size, cost, and performance improvements. The 62EM gate driver is designed for
harsh, high-noise environments, with optional conformal coating.
Equus Computer Systems, Inc. has announced its launch of the
Nobilis i2091R4, a highly scalable 4U rackmount server with more
than 600 terabytes of storage capacity. Its highly scalable capacity
and outstanding performance makes the Nobilis i2091R4 ideal for
content delivery, data archiving, video surveillance and capturing,
and law enforcement, such as body cams video retention.
The unique, new top-loading hard drive storage solution supports
60 3.5-inch to 2 x 2.5-inch hot-swappable hard drives. It features
two Intel Xeon E5-2600V4 processors with up to 22 cores each.
Memory includes 16 DIMM sockets, DDR4 2400 (2TB), (LR)
DIMM, and RDIMM. With more than half a petabyte in a compact
4-U box, the Nobilis
i2091R4 has the
capacity and high
caching ability that
makes it a great choice
requiring retention of
video capturing data.
