This reference design consists of a reinforced dualchannel digital isolator, a GaN gate driver, and isolated power supplies. This compact reference design is intended to control GaN in power supplies, DC-to-DC converters, synchronous rectification, solar inverters, and motor control. An open-loop push-pull topology based power supply for gate drivers provides flexibility in PCB routing. The pushpull transformer driver used in the TIDA-00785 operates at 300 kHz, which helps in reducing the size of the isolation transformer, leading to a compact power supply solution.

The TIDA-01255 design is built for isolated CAN communication, which is widely used in automotive environments. In hybrid and electric vehicles (HEV/EVs), a complete high-voltage network is floating with respect to the chassis ground. Isolation is required for the power and communication channels interfaced between floating high- to low-voltage systems. The TIDA-01255 design supports applications with a simple isolated transformer driver to transfer power. This TI Design has a low-transmission delay, which reduces the loop delay and supports higher baud rates of the CAN.

This reference design shows how to detect current from the mA-to-KA range using a busbar-type shunt resistor. The increasing demand of high-capacity batteries in electric vehicles (EVs) and hybrid electric vehicles (HEVs) drives the requirement for larger current spans and highly-accurate current sensors. Obtaining a good accuracy over three decades (mA to A, 1 A to 100 A, and 100 A to 1000 A) is quite challenging due to large amounts of noise in the system. This design solves this problem by using a high-resolution analog-to-digital converter (ADC) and high-accuracy current shunt monitors from TI.
