XTR26020 is a high-temperature, high reliability isolated power transistor driver designed to provide a robust, reliable, compact and efficient solution for driving a large variety of high-temperature, high-voltage, and high-efficiency power transistors. XTR26020 is able to drive normally-On and normally-Off power transistors in Silicon Carbide (SiC), Gallium Nitride (GaN) and standard silicon, including JFETs, MOSFETs, BJTs, SJTs and MESFETs.
The XTR26020 driver implements unprecedented functionality for high-temperature drivers allowing safe operation at system level by preventing any cross-conduction between high-side and low-side switches, through isolated communication between high-side and low-side drivers. Other features include internal voltage regulator, 4-channel transceiver (2 TX and 2 RX) for isolated data transmission with the microcontroller and between high side and low side drivers. The XTR26020 includes one pull-up gate-drive-channel (PU_DR) capable of sourcing a typical 4A peak current and two pull-down gate-drive-channels capable of sinking a typical 2.4A peak current (PD_DR and PD_MC). The PD_DR channel is used for the effective turn-off of the power transistor, while PD_MC channel is used for Active Miller Clamping (AMC) function thanks to its internal gate level detection.
The circuit includes soft shut-down capability that slowly shuts down the power transistor in case of fault. The XTR26020 is able to detect failures due to over-current in the power switch (rail-to-rail, positive and negative current sense) or to UVLO detected on the power supply. In addition, safe start-up and cross-conduction protection are implemented to guarantee safe operation at system level.
The XTR26020 can be used standalone but also as a controller with multiplied drive capabilities using the XTR25020, which is the driver part of the XTR26020 without the isolation transceiver.
