Drivers/High-Temperature ICs

Rugged, Hard Working, Thermal-Resistant Solutions

If you build systems for "under the hood", you know that it is no place for weak design. High temperatures, strong mechanical vibration and fluctuating electromagnetic fields require products based on decades of good architecture, meticulous manufacturing, and robust testing.

The Atmel motor driver family targets brushed and brushless DC motors that operate in standard temperature or more demanding hot engine environments. A wide variety of combinations integrate high-side and low-side output stages so you can easily tailor solutions to suit your customers' needs.

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

  • Rugged design — Atmel’s unique BCD-on-SOI architecture combines high-voltage capability with the benefits of rugged SOI technology: high temperature resistance (T-junctions up to 200°C), excellent radiation hardness, very low leakage currents, low parasitics, high switching frequency, and latch-up immunity.
  • Cost-effective ICs — Atmel driver ICs require few external components because capabilities such as LIN connectivity and diagnostics are built in. The embedded functionality saves you integration and troubleshooting time and lowers cost of goods.
  • Built-in protection — 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.
  • Extensive technical support — Demonstration and evaluation kits, detailed documentation and reference designs, and experienced help from Atmel application engineers get you started designing quickly and to market faster.
