Week Ending: June 14, 2026

The second week of June brought several important announcements for electronics engineers, power supply designers, EV developers, and embedded system engineers. Major developments included new silicon carbide power semiconductors from Infineon, an advanced battery monitoring IC from Texas Instruments, progress in solid-state battery technology, and continued advancements in ultra-fast EV charging infrastructure.

Let’s examine the most significant developments from the past week.

 

1. Infineon Launches New CoolSiC™ JFET Power Devices

Announcement Date: June 2, 2026

Company: Infineon Technologies

Technology: CoolSiC™ 750V and 1200V Normally-Off SiC JFETs

One of the most important power semiconductor announcements this week came from Infineon. The company expanded its CoolSiC™ JFET portfolio with new normally-off variants targeted at AI data centers, industrial power systems, battery disconnect units, eFuse circuits, and solid-state circuit breakers. The portfolio includes new 750V and 1200V devices and additional package options including TO-247-4.

Why It Matters

The rapid growth of AI data centers is creating enormous demand for highly efficient power distribution systems. Every fraction of a percentage point improvement in efficiency can save megawatts of energy in large-scale facilities.

Key benefits include:

·         Lower conduction losses

·         Higher power density

·         Reduced cooling requirements

·         Improved reliability

·         Better suitability for solid-state protection systems

Applications

·         AI server power supplies

·         Industrial DC distribution

·         Energy storage systems

·         EV charging infrastructure

·         Solid-state circuit breakers

 

2. Infineon Introduces Industry’s First SiC Bidirectional Switch

Announcement Date: June 2, 2026

Company: Infineon Technologies

Technology: 750V CoolSiC™ G2 Bidirectional Switch

Infineon also announced the industry’s first silicon carbide bidirectional switch based on its CoolSiC™ Generation 2 technology. The device integrates two power switches in a common-drain configuration within a single package.

Why It Matters

Bidirectional switches are becoming increasingly important in:

·         AC power converters

·         Matrix converters

·         Solid-state transformers

·         Grid-tied energy systems

The new device simplifies circuit design while reducing component count and improving efficiency.

Designer Perspective

This type of component may accelerate development of next-generation solid-state transformers and advanced AC-AC conversion systems where bidirectional current flow is required.

 

3. Texas Instruments Launches BQ79826Z-Q1 Battery Monitor

Announcement Date: June 9, 2026

Company: Texas Instruments

Part Number: BQ79826Z-Q1

Texas Instruments introduced what it describes as the industry’s highest-cell-count battery monitor with integrated Electrochemical Impedance Spectroscopy (EIS).

The new BQ79826Z-Q1 can monitor up to 26 series-connected cells while incorporating an integrated EIS engine capable of analyzing battery health in real time.

Key Features

·         Monitoring of up to 26 cells

·         Integrated EIS technology

·         Less than 2mV voltage measurement accuracy

·         Functional safety support

·         Early thermal runaway detection

Why It Matters

Battery management systems are becoming increasingly intelligent.

Traditional BMS solutions primarily measure:

·         Voltage

·         Current

·         Temperature

The new EIS capability provides insight into the chemical condition of battery cells, potentially allowing failures to be detected before they become safety hazards.

Applications

·         Electric vehicles

·         Energy storage systems

·         Industrial battery packs

·         Data center backup systems

 

4. Solid-State Batteries Reach Road Testing Stage

Announcement Date: June 11, 2026

Companies: Stellantis and Factorial Energy

Technology: FEST® Solid-State Battery

One of the most significant EV developments this week was the announcement that Stellantis has integrated Factorial’s FEST® solid-state battery technology into a Dodge Charger Daytona development vehicle.

This marks one of the first real-world road-testing programs involving advanced solid-state batteries in North America.

Potential Benefits

Compared to conventional lithium-ion batteries:

·         Higher energy density

·         Faster charging

·         Improved safety

·         Better thermal stability

·         Extended driving range

Why Engineers Are Watching

Solid-state batteries have been discussed for years, but real-world vehicle testing is a major milestone toward commercialization.

 

5. BYD Demonstrates 1.5MW Flash Charging Technology

Company: BYD

Technology: Flash Charging Platform

BYD continued demonstrating its next-generation Flash Charging technology capable of charging compatible EVs from 10% to 97% in approximately 9 minutes using a 1.5MW charging platform.

Technical Highlights

·         1500kW charging capability

·         Standard CCS2 connector

·         Approximately 200 miles of range added in 5 minutes

·         Integrated battery energy storage at charging sites

Industry Impact

This technology addresses one of the largest barriers to EV adoption: charging time.

If deployed at scale, charging durations could begin approaching the convenience of conventional fuel stations.

 

Technology Trend of the Week

Intelligent Power Systems

A clear trend emerged across multiple announcements this week.

Whether examining:

·         Infineon’s SiC JFETs

·         TI’s intelligent battery monitor

·         Solid-state battery development

·         Megawatt EV charging

the common theme is the transition toward intelligent power systems.

Future power electronics will increasingly combine:

·         Advanced semiconductors

·         Real-time diagnostics

·         Predictive monitoring

·         Higher efficiency

·         Software-defined control

This trend is expected to accelerate across EVs, energy storage systems, industrial automation, and AI infrastructure.
