ASIL-certified power MOSFET driver

27 February 2019 Power Electronics / Power Management

The AMT49105 is Allegro MicroSystems Europe’s newest ISO 26262 compliant N-channel power MOSFET driver, designed to simplify motor system designs and provide footprint reduction by integrating power analog system requirements.

Thanks to a robust output gate drive, this device can be used in a wide range of applications, including power applications in excess of 1 kW. Additionally, it provides the LIN transceiver, regulated microprocessor supply, phase monitors for sensorless BLDC control, and other features that reduce overall power consumption for today’s efficient vehicles.

The AMT49105 is well-suited for high-power inductive safety automotive and industrial applications, such as engine cooling fans, braking and multiple pump applications, where supplies range from 5,5 V to 50 V. Advanced diagnostics monitor and indicate system faults, internal faults and power bridge faults to assure safe systems operation.

The chip is designed to the ISO 26262 standard and is compliant to an ASIL-B level. It is supplied in a small 48-lead QFN package with exposed thermal pad, reducing the footprint by approximately 40% compared to an equivalent QFP.
