Power Distribution Unit (PDU)

Optimize your Power Distribution Units for AI Data Centers.

Build safer, more efficient 800V power distribution for AI data center sidecars and racks. When engineering a high-density PDU for data center applications, absolute precision is paramount. Allegro provides the critical semiconductor backbone for your modular data center PDUs, enabling the ultimate in power density and system uptime through:

  • Ultra-fast XtremeSense™ tunnel magnetoresistance (TMR) and Hall based current sensors that protect every PDU in data center environments with sub microsecond fault detection.
  • Robust Power-Thru™ isolated gate drivers to enable high frequency SiC switching.
  • Code-free motor drivers for reliable cooling fan control.
