Powering and cooling the next generation of AI data centers for maximum system uptime and efficiency.
As facilities transition to 800VDC architectures, they require a new standard of precision to manage extreme power density and heat. Allegro delivers the critical semiconductor solutions required to safely power and cool AI compute from the power rack down to the server board:
High-Density Power Delivery: Power-Thru™ isolated gate drivers maximize the efficiency of wide-bandgap SiC and GaN devices, drastically shrinking the system footprint.
Mission-Critical Uptime: XtremeSense™ TMR current sensors provide nanosecond fault protection and accurate system telemetry for real-time power monitoring.
Intelligent Thermal Management: Advanced QuietMotion™ motor drivers power the mission-critical cooling infrastructure, enabling highly efficient, low-noise rack fans and code-free, sensorless drive for liquid cooling pumps.
Fortify 800V power delivery across next generation AI racks and sidecars. Ultra-fast XtremeSense TMR current sensors deliver nanosecond fault detection, robust Power-Thru isolated gate drivers enable high frequency switching, and code-free motor drivers keep cooling reliable.
Layered power protection for volatile GPU loads. XtremeSense TMR sensors provide 10 MHz feedback so Capacitive Backup Units absorb load swings, while Power-Thru isolated gate drivers maximize SiC efficiency across BBU and UPS designs.
Optimize AC/DC and DC/DC conversion for extreme power density. Allegro pairs high-bandwidth XtremeSense™ TMR current sensing, Power-Thru™ isolated gate drivers, and code-free QuietMotion™ fan control to maximize efficiency, reliability, and power delivery.
Meet aggressive Power Usage Effectiveness (PUE) targets across air, hybrid, liquid and immersion cooled data center architectures. Allegro's code-free QuietMotion motor drivers with Field-Oriented Control deliver whisper-quiet fan and pump control for the most demanding AI thermal loads.
