ISO6720-Q1

The ISO6720-Q1 is a high-reliability isolated gate driver from Texas Instruments designed for industrial and automotive applications. It features a 5.7 kV RMS isolation barrier, ensuring safe and reliable signal transmission across electrically isolated domains. The device supports both high-side and low-side switching configurations, making it suitable for use in half-bridge and full-bridge topologies commonly found in motor drives, power supplies, and inverters. This isolated gate driver includes integrated bootstrap circuitry for driving high-side MOSFETs or IGBTs, eliminating the need for external components in many applications. It offers a propagation delay of typically 90 ns, with low jitter (±10 ns), enabling precise timing control critical in high-frequency switching systems. The output drive strength is optimized to deliver up to 2 A peak current, allowing fast switching transitions that reduce switching losses and improve efficiency. Compliant with AEC-Q100 Grade 1 qualification, the ISO6720-Q1 is built for harsh environments such as automotive powertrains and battery management systems. Its wide operating temperature range—from –40°C to +125°C—ensures robust performance under extreme thermal conditions. The device also features overcurrent protection and desaturation detection, enhancing system safety by preventing damage from abnormal load conditions. The ISO6720-Q1 uses a compact SOIC-16 package, reducing board space requirements while maintaining excellent thermal performance. It supports supply voltages from 3.3 V to 15 V on the low-side side and up to 15 V on the high-side side, offering flexibility in system design. Additionally, the internal charge pump eliminates the need for an external auxiliary power supply, simplifying the overall design and lowering BOM cost. Designed for use in traction inverters, DC-DC converters, and onboard chargers, this IC enables efficient and reliable operation in electric vehicles and industrial automation equipment. Its robust isolation and advanced protection features make it ideal for applications requiring high noise immunity and long-term reliability in demanding electrical environments.
