Power Integrations Launches SCALE EV: Automotive-Qualified IGBT/SiC Module Driver Family; Targets Bus, Truck and Con-Ag EVs

Power Integrations (NASDAQ:
POWI), the leader in gate driver technology for medium- and high-voltage inverter
applications, today announced the SCALE TM EV family of gate-driver boards for Infineon
EconoDUAL TM modules. Suitable for original, clone and new SiC variants, the driver targets
high-power automotive and traction inverters for EV, hybrid and fuel-cell vehicles including
buses and trucks as well as construction, mining and agricultural equipment.

SCALE EV board-level gate drivers incorporate two reinforced gate-drive channels,
associated power supplies and monitoring telemetry. The new boards are automotive-
qualified and ASIL B certified, enabling implementation of ASIL C traction inverter designs.
The first SCALE EV family member to be released is the 2SP0215F2Q0C, designed for the
EconoDUAL 900 A 1200-volt IGBT half-bridge module.

Peter Vaughan, director of automotive business development at Power Integrations, said:
"Gate-driver design is critical to both the performance and reliability of electric vehicles. By
offering a product where the development, testing and qualification plus ASIL certification
have already been done, we are dramatically reducing development time and cost.”

The high level of integration provided by innovative new driver ICs enables the entire driver
board, including gate power, to fit onto the outline of the power module, while still
providing the spacing necessary for reinforced isolation according to the IEC 60664
standard. The ASIC package provides 11.4 mm of creepage and clearance, specifically
designed to meet the requirements for 800volt vehicle system voltages. Input and output

lines to the system microcontroller are connected via two independent on-board connectors
to meet functional safety requirements. A single 5 V supply per channel is required, with
other isolated voltages being generated on the board itself.

The SCALE EV gate-driver family is rated at 1200 V for 400-volt and 800-volt systems and
supports both silicon carbide (SiC) MOSFETs and silicon IGBTs. The design carries a 5500-
meter altitude rating and is optionally available with conformal coating for technical
cleanliness requirements. The design includes a wide range of protection provisions,
including active short-circuit, active discharge of connected DC-link capacitor, overvoltage
limitation via active gate control, diagnostic function such as gate monitoring, signal
transmission monitoring and on-chip temperature monitoring, and short-circuit and over-
current response of less than one microsecond for SiC MOSFETs and less than three
microseconds for IGBTs.

Availability & Resources
Support materials for SCALE EV include the data sheet, pressFIT tool CAD design, the
RDHP-2250Q adaptor breakout board and PC-based software. Power Integrations offers
design services to tune switching performance for specific IGBT or SiC die, and to customize
the layout for novel module form-factors. Samples of the 2SP02152FQ are available now,
with full production release in the fourth quarter of 2022. Pricing starts at $200 each for
100-piece quantities.
