MOSFET Driver Is ASIL Certified

Allegro MicroSystems unveils the AMT49105, its latest ISO-26262 and ASIL-B compliant N-channel power MOSFET driver. The device promises to simplify motor systems designs and provides a footprint reduction by integrating power analog systems requirements. It can be used in a wide range of applications, including power applications beyond 1 kW. Additionally, the AMT49105 integrates the LIN transceiver, regulated microprocessor supply, phase monitors for sensor-less BLDC control, and other unique features that reduce overall power consumption.


The AMT49105 is viable for use in high-power, inductive-safety automotive and industrial applications such as engine cooling fans, braking and multiple pump applications where supplies range from 5.5V to 50V. Diagnostics monitor and indicate system faults, internal faults, and power bridge faults to ensure safe operation.
