We offer Driver and Controller ICs for a range of applications: Ballast Controllers for fluorescent lighting, Motor Drivers/Controllers for various motor types, Pushbutton Controllers, and Relay Drivers.

Fluorescent based lamp technology is seeing a revival because it is used by UV-C disinfection lamps, which have gained strong momentum due to the COVID-19 pandemic. Today, they can be run by Ballast Control ICs which integrate all functions required to operate fluorescent lamps such as preheat-, ignition-, run-mode and protection features required by state-of-the-art and future fluorescent lamp ballasts.

With the steady push towards higher energy efficiency, the use of variable speed motor control drivers in industrial, automotive, and consumer markets is growing continuously. Designers are constantly seeking easier and faster ways to integrate the required control algorithms.

BDC motor controllers typically have an H-bridge configuration whose switching action supplies electricity and rotates the motor. A BLDC motor controller controls the motor’s speed and torque, as well as starting, stopping, and reversing its revolution.

Pushbutton controllers can accept an electrically noisy input from a mechanical switch or pushbutton, and produce a clean, latched digital output after a factory-set qualification delay. They eliminate contact bounce during switch opening and closing.

Relay Driver ICs provide the interface between the low voltage, low energy outputs of a digital device such as a microcontroller, and the higher power demands of a switching relay input. While translating signal energy levels, they also provide protection from the relay’s inductive kickback, and open-load and short-circuit fault detection.
