IXYS Introduces Two Gate Drive and Regulator ICs for Enabling Microcontroller Based Digital Power Management, Including Power Fa

Business Wire
IXYS Corporation (NASDAQ:SYXI) announces the release of the IXI858
and IXI859 Gate Driver/Regulator in its family of Interface
products. These ICs are designed to provide the needed analog
functions required by microcontrollers to implement offline digital
power supply control, such as in Power Factor Correction (PFC). The
IXI858/859 combine a gate drive, low voltage linear regulator and a
charge pump function for drive voltage generation as needed in
these applications. These features make the IXI858/859 invaluable
for implementing microcontroller based PFC systems. The IXI858/859
can be used in combination with a Depletion-Mode Power MOSFET such
as the IXTY02N50D, which can be used to create a constant current
source to provide offline standby power at lower cost with lower
high line power consumption. The IXI858 is designed to support 5.0V
digital systems with an on board 5.0V linear regulator, while the
IXI859 features a 3.3V linear regulator for lower voltage systems.
In addition, both versions feature logic level input signal
compatibility, 60mA source and 120mA sink gate drive output and a
charge pump section meant to generate a 13V gate drive voltage. The
growing trend of digital power management, with the use of standard
microcontroller in motor control, power supply, and PFC circuits
require the interface, voltage gain and drive of the IXI858/859 for
digital power management. The IXI858 and 859 were optimized for
cost efficiency to support high volume applications such as
dimmable ballast, non-dimmable ballast and High Intensity Discharge
(HID) lighting systems. The IXI858/859 are offered in a small
8-Lead SOIC surface mount package, with rated operation of
-25(degrees)C to +125(degrees)C. This package is offered in tubes
quantities of 100 or tape and reel quantities of 2500. Further
