ISO6760-Q1

The ISO6760-Q1 is a high-reliability isolated gate driver from Texas Instruments designed for industrial and automotive applications. It features a 3.5 kV RMS isolation barrier, ensuring robust electrical separation between the control circuit and power stage while maintaining signal integrity in harsh environments. The device supports both high-side and low-side configurations, making it suitable for use in half-bridge and full-bridge topologies. This gate driver delivers a peak output current of up to 1.5 A, enabling fast switching speeds and efficient operation of power MOSFETs and IGBTs. It includes integrated bootstrap diodes and a dedicated VDD supply pin, simplifying the design process by reducing external component count. The propagation delay is tightly matched between channels, minimizing dead time errors in synchronous switching applications. Compliant with AEC-Q100 Grade 1 qualification, the ISO6760-Q1 is engineered for automotive-grade reliability under extreme temperature conditions—from -40°C to +125°C. Its wide input voltage range (from 3.3 V to 5 V) allows compatibility with various logic-level controllers, including microcontrollers and digital signal processors. The device also incorporates comprehensive protection features such as undervoltage lockout (UVLO), short-circuit protection, and thermal shutdown, enhancing system safety and longevity. The ISO6760-Q1 offers flexible drive strength control via an external resistor, allowing optimization of switching performance based on load requirements. It supports both non-inverting and inverting logic modes, increasing versatility across different power conversion architectures. Additionally, the device’s compact SOIC-16 package facilitates space-efficient PCB layouts, which is critical in densely packed electronic systems. Applications include electric vehicle powertrains, onboard chargers, DC-DC converters, motor drives, and industrial power supplies where galvanic isolation, high efficiency, and robustness are essential. Its ability to operate reliably in high-noise environments makes it ideal for use in motor control systems and renewable energy inverters.
