IXI858 / IXI859
Gate Driver with VReg and Charge Pump Regulator
The IXI858 and IXI859 Gate Driver / Re-
gulator ICs are part of IXYS growing fa-
mily 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 Correc-
tion (PFC).
The IXI858 / 859 combine a power gate
drive, low voltage linear regulator and
a charge pump function for drive vol-
tage 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 com-
bination with a Depletion-Mode Power
MOSFET such as 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.

IXI848 / IXI848A
High-Side Current Monitor
The IXI848 / IXI848A is precision high
side current sense monitor. High side
power-line monitoring offers the advan-
tage of allowing the ground plane to
remain undisturbed when sensing load
currents.
An external sense resistor sets the ran-
ge of the amplified ground-referenced
output monitoring voltage. The output
voltage is amplified by a selectable fixed

The IXI858 is designed to support 5.0 V
digital systems with an on board 5.0 V
linear regulator, while the IXI859 fea-
tures a 3.3 V linear regulator for lower
voltage systems. In addition, both versi-
ons feature logic level input signal com-
patibility, 60 mA source and 120 mA sink
gate drive output and a charge pump
section meant to generate 13 V gate
drive voltage.
The growing trend of digital power ma-
nagement, with the use of standard
microcontroller in motor control, pow-
er supply, and PFC circuits require the
interface, voltage gain and drive of the
IXI858 / 859 for the digital power ma-
nagement. The IXI858 / 859 were opti-
mized for cost and efficiency to support
high volume applications such as dim-
mable ballast, non-dimmable ballast and
High Intensity Discharge (HID) lighting
systems.
gain of either 10 or 50. With an input
voltage range up to 40 V for IXI848 and
60 V for IXI848A, and output gain of up
to 50, the IXI848 / IXI848A are designed
to address a wide variety of current sen-
se applications.
The IXI848 / IXI848A operates over a
temperature range of -40°C to +85°C.
The IXI848 / IXI848A are available in an
8-Lead SOIC package.
