• Two LVDS OpenLDI input ports (shares pins with
the 2nd DRGB input) in 1-ch or 2-ch input mode, with
100MHz (max) per channel in 1-ch mode or 160MHz
in 2-ch mode
• Support either one full HD input (1080p) or two HD
inputs (720p)
Provide system flexibility to drive most LCD panels:
LCD path for TTL/TCON up to 24-bit DRGB, 160MHz
(max)
• LVDS OpenLDI: dual channel, 100MHz (max) per
channel in 1-ch mode or 160MHz in 2-ch mode
• TW8844 supports 4-lane MIPI-CSI2 output for up to
1080p, with up to 1Gb/lane
• TW8845 supports BT.656 output to the SoC with
resolutions up to 720p
Two input measurement engines with frozen/abnormal
image detection diagnostics to monitor input from the
SoC and camera
EEPROM fast boot allows register programming
without need for external microcontroller
Two separate H/V scalers for outputting up to 1080p
(1920 x 1080) resolution, allowprocessingof twodifferent
sources simultaneously, while outputting different data
to the SoC and display, or they can simultaneously drive
two different displays with different content
Automatic Contrast Adjustment (ACA), white balance
and gamma correction optimizes video quality
Smooth input switching allows switching between
various input sources without screen flicker
AEC-Q100 Grade-2 qualified for operation from -40°C
to +105°C
The TW8844 and TW8845 can be combined with
Renesas’ R-Car SoC family, as well as the ISL78302
dual LDO, ISL78322 dual 2A/1.7A synchronous buck
regulator, and ISL78228 dual 800mA synchronous
buck regulator to provide power rails for the TW884x,
SoC and other key components on the automotive
infotainment system board.

VPG Foil Resistors Announces Ultra-High
Precision Military and Space Grade Resistors
for High-Performance Current Sensing within
Mission-Critical Applications
The VPG Foil Resistors product group of Vishay
Precision Group (NYSE: VPG) (www.vpgfoilresistors.
com), manufacturers of the industry’s most precise and
stable precision resistors, today introduced the Model
303337 ultra-high precision military and space-grade
resistor, offering high-performance current sensing
within mission-critical applications.
The Model 303337 produces a highly precise voltage
that is directly proportional to measured current levels,
with significantly reduced component sensitivity to
applied power changes, including PCR and thermal
resistance values. The industry-exclusive design of
the Model 303337 incorporates VPG’s own proprietary
Bulk Metal® Z Foil resistive technology, along with a
four-terminal Kelvin connection, for ultra-high precision
current sensing and temperature stability to 3W.
Additional attributes include a low temperature coefficient
of resistance (TCR) of ±5 ppm/°C (–55°C to +125°C, at
+25°C ref.), for reduced risk of measurement errors due
to temperature changes; improved load-life stability of
±0.02% (typ.), at +70°C for 2000 hours (rated power);
a low power coefficient of resistance (PCR) of 5 ppm/W
at rated power; a resistance tolerance to ±0.1%; a 100
to 200 mΩ resistance range; a short-time overload of
0.005% typical; an electrostatic discharge (ESD) limit of
< 25 kV; solderable terminations; and a choice of either
lead (Pb)-free or tin/lead alloy solder finish.
To ensure total resistor reliability and conformance to
