How can the latest innovations in electric vehicle technology contribute to extending their driving range, an issue at the forefront of the industry? 

Senior Director at Allegro MicroSystems, Ram Sathappan, shed some light on the company’s breakthroughs in magnetic sensors and power ICs, while discussing the significant role of energy conversion efficiency in electric vehicles at CES 2024.

“And for that, what we have done is we have created some of the most accurate and high bandwidth current sensors out there, that pair along with their high voltage gate drivers for wide band gap power electronic switches. The combination of those two work very well in creating systems that are smaller, lighter, and allow you to save space and weight, which in the long run actually ends up extending the driving range,” Sathappan said.

Good morning, everyone. My name is Ram Sathappan. I'm a senior director at Allegro MicroSystems. I wanted to talk to you here about the latest in e-mobility. Are we there yet with extending the range of electric vehicles? I think that's a question on everyone's mind. And I believe we are with the new products, the innovative products coming from Allegro MicroSystems. Allegro MicroSystems, as you may know, is the market leader in magnetic sensors are the, market share leader. We not only do magnetic sensors. We are a leader in also power ICs. I'm here to talk to you about energy conversion in electric vehicles. It's a very key concern of automotive manufacturing companies, automotive product companies. They're all looking to figure out how we can make it more efficient so that we can extend the driving range of vehicles And what we have in front of us is some components here that Allegro Microsystems builds that go into electric powertrain, all these electric vehicles. So what we have in front of us is two key components that I wanna talk about. What it is is that you have, what we call the magnetic current sensors that Allegro is a market leader in. As well as isolated gate drivers, high voltage isolated gate drivers. That's another innovation from Allegro MicroSystems. The combination of these two components help bring in more efficient power conversion systems, which is at the heart of the electric powertrain of a vehicle. So you have in the electric powertrain, typically, what is it? What what comes up first when you connect your charging plug to a car is a onboard charger, and then you have a battery management system at DCDC converter and a traction motor inverter. All of these systems, what they are doing is really converting power power conversion from AC to DC or DC to DC or DC to AC when we are doing these conversions, there is some energy loss always happening. And the, you know, the thing that most engineers care about is how do we make it keep it efficient, reduce power loss and improve the performance of the system. And for that, what we have done is we have created some of the most accurate and high bandwidth current sensors out there. That pair along with their high voltage gate drivers for wide band gap power electronic, switches. The combination of those two work very well in creating systems that are smaller, lighter, and allow you to save space and weight, which in in turn in the long run actually ends up extending the driving range of the vehicle.

OpenAI's GPT-6 Astra pitch is to skip integrations and run the software UI itself

OpenAI's GPT-6 Astra pitch is to skip integrations and run the software UI itself

OpenAI shipped GPT-6 Astra on Sept. 3 with a "computer use" capability that lets the model operate existing software UIs directly instead of requiring custom API integrations. The staged rollout through Daybreak, ChatGPT tiers, and AWS shifts the automation bottleneck from building connectors to governing UI-driven sessions, with speed measured in minutes per task as the cost input.

  • 01Astra operates software via pixels, keyboard, and mouse interactions to bypass API integration work on the long tail of internal tools without clean API access
  • 02OpenAI reported Astra at 40 minutes per task (47% faster than GPT-5.6 Sol at 75 minutes), making task time the practical proxy for compute cost modeling and throughput evaluation
  • 03Enterprises must define governance before broad rollout: eligible workflows for UI automation, audit logging systems, identity and secrets handling, and fallback procedures when UIs change or sessions break

Cloud is set to take 26% of IT budgets, and hiring is shifting toward platforms

Cloud is set to take 26% of IT budgets, and hiring is shifting toward platforms

Foundry’s 2026 Cloud Computing Study, cited by CIO, reports IT leaders expect 26% of IT budgets to go to cloud computing in the next year and that 74% accelerated cloud migrations in the last 12 months. At the same time, CIO’s coverage of Robert Half Technology’s 2026 IT salary report shows AI/ML engineers at a $170,750 median salary and a striking capability gap, with only 7% of leaders saying they have the capabilities to complete prioritized projects and 65% expecting to upskill existing staff. Separate reporting from Nextgov on senior appointments in the Pentagon CIO office, and Government Technology’s account of Illinois’ multi-agency data-sharing MOU, indicate large organizations are staffing for organizational change, governance, and cross-domain data sharing, not just for lift-and-shift migrations. For enterprise operators, the signal is that cloud programs increasingly depend on internal platform engineering, adoption enablement, and finance-aligned governance, because those functions connect migration speed to day-two operations and business results.

  • 01A useful benchmark for 2026 planning: Foundry’s survey puts cloud at 26% of IT budget next year, so showback/FinOps and workload-level chargeback governance can’t stay a side project (per CIO citing Foundry).
  • 02Talent pricing has become an input to architecture decisions. A CIO, citing Robert Half, compared the median pay for AI/ML engineers ($170,750) with systems administrators ($98,000), arguing that platform standardization and self-service guardrails are as much about labor strategy as technology.
  • 03If 65% of leaders expect to upskill to close gaps, the differentiator becomes your internal adoption system, in-app guidance, runbooks, and training telemetry, not the third new tool in the stack (per CIO citing Robert Half; illustrated by Ferring’s Whatfix rollout reported by BankInfoSecurity).

AI agents are pushing access controls and testing into the data layer

AI agents are pushing access controls and testing into the data layer

Snowflake is warning that dashboard-era access controls do not hold up once AI agents can query and act across datasets, pushing governance closer to the data layer, according to TechTarget’s Computer Weekly. In parallel, TechTarget reported that enterprise AI-agent testing needs to expand beyond pre-deployment checks into continuous monitoring so agents don’t drift beyond prescribed instructions. InformationWeek’s reporting on CISOs at Intuit, Smartsheet and ETS adds the operational risk: unmanaged “AI orphans” and identity sprawl as agent count grows, which shifts near-term workload onto IAM, data governance and platform engineering teams building the guardrails.

  • 01If an AI agent can reach multiple tools, the real control plane becomes the data layer and identity, not the BI dashboard permissions model.
  • 02Agent rollouts that stop at pre-production testing are likely to miss the failure mode operators actually see, post-deploy tool changes that alter what the agent can do.
  • 03“AI orphans” is a practical inventory problem: if teams can’t enumerate agents, they can’t set ownership, secrets rotation, or access reviews on a schedule.
