DALLAS, May 9, 2023
/PRNewswire/ -- Texas Instruments (TI) (Nasdaq: TXN), a leader in
high-voltage technology, today debuted a highly integrated,
functional safety-compliant, isolated gate driver that enables
engineers to design more efficient traction inverters and maximize
electric vehicle (EV) driving range. The new UCC5880-Q1 reinforced
isolated gate driver offers features that enable EV powertrain
engineers to increase power density and reduce system design
complexity and cost while achieving their safety and performance
goals. For more information, see TI.com/UCC5880-Q1.
As EVs continue to grow in popularity, semiconductor innovations
in traction inverter systems are helping overcome critical barriers
to widespread adoption. Automakers can build safer, more efficient
and more reliable silicon carbide (SiC)- and insulated-gate bipolar
transistor (IGBT)-based traction inverters by designing with
UCC5880-Q1, featuring real-time variable gate-drive strength,
Serial Peripheral Interface (SPI), advanced SiC monitoring and
protection, and diagnostics for functional safety.
"Designers of high-voltage applications like traction inverters
face a unique set of challenges to optimize system efficiency and
reliability in a small space," said Wenjia
Liu, product line manager for high-power drivers at TI. "Not
only does this new isolated gate driver help enable engineers to
maximize driving range, but it also integrates safety features to
reduce external components and design complexity. And it can be
easily paired with other high-voltage power-conversion products
such as our UCC14141-Q1 isolated bias supply module to improve
power density and help engineers reach the highest levels of
traction inverter performance."
Maximize EV driving range while reducing design complexity
and cost
The need for higher reliability and power performance for EVs is
continuously growing, as efficiency gains have a direct impact on
operating range improvement per charge. But achieving any increase
in efficiency is difficult for designers, given that the majority
of traction inverters already operate at 90% efficiency or
higher.
By varying the gate-drive strength in real time, in steps
between 20 A and 5 A, designers can improve system efficiency with
the UCC5880-Q1 gate driver as much as 2% by minimizing SiC
switching power losses, resulting in up to 7 more miles of EV
driving range per battery charge. For an EV user who charges their
vehicle three times per week, that could mean more than 1,000
additional miles per year. To learn more, read the technical
article, "How to Maximize SiC Traction Inverter Efficiency with
Real-Time Variable Gate Drive Strength."
In addition, the UCC5880-Q1's SPI programmability and integrated
monitoring and protection features can reduce design complexity as
well as external component costs. Engineers can further reduce
components and quickly prototype a more efficient traction inverter
system using the SiC EV Traction Inverter Reference Design. This
customizable, tested design includes the UCC5880-Q1, a bias-supply
power module, real-time control MCUs and high-precision
sensing.

TI is showcasing high-voltage innovations for a sustainable
future, including the UCC5880-Q1, at the 2023 Power Conversion and
Intelligent Motion (PCIM) Europe
conference May 9-11. Demonstrations
will show system-level innovations for gallium nitride (GaN)- and
SiC-based designs as well as other TI technologies to increase
power density and efficiency for EVs, power supplies, energy
storage systems and more. Visit TI at Hall 7, Booth No. 459, or see
TI.com/PCIM for more information.
Throughout the conference, TI power experts will present in five
sessions to address high voltage, high power density and low
electromagnetic interference design challenges. Their schedule is
available at TI.com/PCIM.
TI is committed to helping engineers unlock the power of
high-voltage technology with innovations in power conversion and
wide band-gap semiconductors.
