Thanks to a robust output gate unit, this device can be used in a wide range of applications, including those with power ratings > 1 kW. Furthermore, the AMT49105 provides a LIN transceiver, microprocessor-regulated power supply, phase monitors for sensorless BLDC control, and other unique features that reduce the overall power consumption required in today's efficient vehicles.
The AMT49105 is an excellent fit for high-power inductive safety industrial and automotive applications, such as engine cooling fans, brakes, and multi-pump applications where supplies range from 5.5 V to 50 V. Advanced diagnostics monitor and indicate system faults, internal faults, and power bridge failures to ensure safe system operation. The AMT49105 is designed to the ISO-26262 standard and meets ASIL-B level requirements.
“We are delighted to add this ASIL-certified device to our portfolio of more than 30 ISO 26262-compliant devices,” said Vijay Mangtani, Vice President of Allegro’s Power IC business unit. “We are committed to moving technology, and the world, toward a safer future.”
The Allegro AMT49105 is supplied in a small, 48-lead QFN package with an exposed thermal pad, reducing the footprint by approximately 40% compared to an equivalent QFP. This package is lead-free (Pb) with a matte 100% tin-lead coating.
