Motor Drivers


Our motor drivers target applications with Brushed DC (BDC), Brushless DC (BLDC) and stepper motors intended for use in standard temperatures, as well as in demanding high-temperature "under-the-hood" conditions.

Robust and Versatile MOSFET Drivers


Our driver portfolio includes ICs for small DC motors that are controlled directly from the output stages. At the heart of this portfolio are motor driver System Basis Chips (SBCs) with integrated gate drivers or pre-drivers to control separate N-channel MOSFETs. These drivers can be used to control almost any size N-channel MOSFET in a broad range of applications.

Motor Drivers and Power Supply in a Single Device


Our 3-phase brushless motor drivers and brushed DC gate drivers combine a power supply and a microcontroller to create cost-efficient motor driver SBCs. These SBCs also include a communication port that is Grade 0 and Grade 1 rated for use in harsh automotive conditions. Your design will require fewer external components which will reduce your circuit design complexity, lower your overall BOM cost and speed up your time to market.

Flexible Fan Control Options


Improve system performance in computing, mass storage, networking and other applications with our portfolio of fan controller ICs. Our closed-loop fan controllers feature look-up tables, PID loop control and alerts for locked rotors and blocked air paths. The majority of our PWM and linear fan controllers feature integrated temperature sensing, making them great all-in-one solutions for a variety of embedded applications.
