The isolated gate drive & sense signal chains combine robust switch control and scalable multichannel monitoring into a flexible solution covering a range of AC/DC and DC/AC applications. Isolated gate drive & sense combines ADI’s isolated gate drivers, isolated power solutions, and precision converter technology to deliver a signal chain that provides output drive and protection for power switches including IGBTs and fast switching silicon carbide (SiC) devices, while also offering high accuracy monitoring of system voltages, currents and temperatures using combinations of digital isolation, amplifiers, and high precision ADCs.

Solutions target applications such as automotive traction inverter/OBC, high power test, power inverters, power supplies, energy storage, and robotics. Different isolated gate drive & sense signal chain configurations target key areas such as highest protection/monitoring vs. small footprint, and cover key requirements in terms of gate drive, short-circuit protection, low delay, working voltage, high frequency switching, fast error response on the drive side, and scalable monitoring to deliver performance in accuracy, speed, and resolution on the sense side.
