Under the hood with Atmel tech

Engineers building complex systems slated for “under the hood” tasks know there is little room for weak designs in such demanding environments.

Indeed, high temperatures, strong mechanical vibration and fluctuating electromagnetic fields demand the inclusion of products based on decades of optimized architecture, meticulous manufacturing and robust testing.

And that is why Atmel’s motor driver family targets brushed and brushless DC motors capable of operating in standard temperature – or even more demanding hot engine environments.

“A wide variety of combinations integrate high-side and low-side output stages so manufacturers can easily tailor solutions to suit customer needs,” an Atmel engineering rep told Bits & Pieces. “Plus, our driver portfolio includes ICs for small DC motors controlled directly from the output stages, as well as motor driver system basis chips, with integrated gate drivers or pre-drivers to control separate NMOSFETs of almost any size.”

Key features include rugged design, with Atmel’s unique BCD-on-SOI architecture combining high-voltage capability with the benefits of rugged SOI technology: high temperature resistance (T-junctions up to 200°C), optimized radiation hardness, very low leakage currents, low parasitics, high switching frequency and latch-up immunity.

We also offer cost-effective ICs that require few external components, because capabilities such as LIN connectivity and diagnostics are already built in. Plus, all Atmel drivers share the same protective features—over-temperature warning and switch-off, as well as under-voltage, over-current, short-circuit and open-load detection.
