Complete analogue system solution for systems using external microprocessors

Allegro MicroSystems Europe has released the AMT49105, its newest ISO-26262 compliant N-channel power MOSFET driver. The device simplifies motor systems designs and offers footprint reduction by combining power analogue systems demands. Due to a robust output gate drive, this device can be employed in a broad range of applications, including power applications >1KW. Also, the device offers the LIN transceiver, regulated microprocessor supply, phase monitors for sensorless BLDC control and other individual features that lessen overall power consumption demanded by today’s efficient vehicles. "We're excited to add this ASIL-certified device to our portfolio of over 30 other devices compliant with ISO 26262," said Vijay Mangtani, vice president of Allegro's Power IC Business Unit. "We're committed to moving technology - and the world -towards a safer future." The device is supplied in a small 48-lead QFN package with exposed thermal pad lessening the footprint by approximately 40% in contrast to an equivalent QFP. This package is lead (Pb) free with 100% matt-tin lead frame plating.
