Datacenter & Telecom Systems

You need both reliability and extreme energy efficiency to meet modern demands for always-on data access. We can help you keep your servers running reliably 24/7 while also accounting for every milliwatt of potential energy savings.

Check out our single chip, small form factor power and current measurement sensor ICs for reduced ohmic losses. We also provide fan motor driver ICs that help you to meet stringent efficiency and audible noise standards—using sensorless and sinusoidal commutation, soft switching, phase advance, soft start and flexible closed loop speed control.
