The MOSFET driver is designed to the ISO-26262 standard and is compliant to ASIL-B level. It can be used in systems that use external microprocessors and simplifies motor system design by integrating power analogue system requirements in one device, says the company.

The device has a robust output gate drive, which allows it to be used in a range of applications, including power applications above 1kW. It also provides the LIN transceiver, regulated microprocessor supply, phase monitors for sensorless BLDC control and other power management features to reduce overall power consumption in vehicles. The MOSFET driver can be used in high power inductive safety automotive and industrial applications, such as engine cooling fans, braking and multiple pump applications, where supplies range from 5.5 to 50V.

Diagnostics monitor and indicate system faults, internal faults and power bridge faults for safe systems operation.

The AMT49105 is supplied in a small 48-lead QFN package with exposed thermal pad. According to Allegro, this reduces the footprint by approximately 40% compared to an equivalent QFP. This package is lead (Pb) -free with 100% matt-tin lead frame plating.
