Dispelling Myths: Don’t believe it when they say you need a bipolar gate drive for eGaN FETs
Use of a negative gate drive can lead to a larger voltage drop during deadtime and severe losses. Andrea Gorgerino, EPC GaN devices have gone from initial R&D to mainstream designs over the last 15 years. Unfortunately, there are many misunderstandings left-over from those early-stage developments or dead-end technology branches. One of the most pernicious […]
Selecting a gate driver for ASIL-certified systems
Several safety features now found in gate driver integrated circuits make it easier for automotive system designs to get ASIL certification. David Divins • Infineon Technologies The Automotive Safety Integrity Level (ASIL) is a risk classification system defined by the ISO 26262 standard for the functional safety of road vehicles. There are four ASIL safety […]

Where depletion-mode power MOSFETs excel
Depletion-mode MOSFETs have qualities that let them work well in several kinds of power-handling circuits. Aalok Bhatt, José Padilla, Raymon Zhou • Littelfuse, Inc. Most MOSFETs are enhancement-mode (EM) devices: When their gate-source voltage is zero, they don’t conduct. When the need is for a switch that is normally on when there is no power […]
High-side gate driver enables wire protection for advanced automotive power distribution
Modern cars feature numerous advanced driver assistance systems (ADAS). Safety-critical ADAS applications must be designed for high availability, and automated driving functions are even more challenging to implement as they introduce fail operational requirements. The impact on the primary power distribution is the introduction of safety elements to guarantee fast failure isolation in less than […]
