Brushless DC Drivers
Automotive Three-Phase MOSFET Gate Driver with Integrated Diagnostics and ASIL D Functional Safety Capability
AMD89111
The AMD89111 is a three-phase N-channel MOSFET gate driver purpose-built for automotive motor control applications. It eliminates the need for external gate supply regulators by integrating a charge-pump regulator that sustains full gate drive down to 5.5 V — and maintains operation without unsafe states down to 0 V. With ASIL D SEooC compliance per ISO 26262, integrated current-sense amplifiers, programmable diagnostics, and a comprehensive self-verification framework, the AMD89111 significantly reduces system component count and simplifies safety certification for high-integrity motor drive designs.
