UCC27517A-Q1

The UCC27517A-Q1 is a high-speed, dual-channel gate driver IC designed for automotive applications, manufactured by Texas Instruments. It features a 5.5-V to 20-V operating supply voltage range, making it suitable for use in harsh environments such as those found in electric vehicles and industrial systems. The device provides a peak output current of up to 6 A (source) and 8 A (sink), enabling fast switching of power MOSFETs and IGBTs with minimal propagation delay—typically 45 ns at 15 V supply. This gate driver includes integrated bootstrap diodes, eliminating the need for external components and reducing board space. It supports both non-inverting and inverting configurations, allowing flexible control of high-side and low-side switches in half-bridge or full-bridge topologies. The input logic threshold is compatible with standard CMOS and TTL levels, ensuring seamless integration with microcontrollers and digital signal processors. One key feature is its robust electrostatic discharge (ESD) protection, rated at ±2 kV HBM, which enhances reliability in automotive-grade applications where electromagnetic interference and transient voltages are common. Additionally, the UCC27517A-Q1 incorporates thermal shutdown protection and undervoltage lockout (UVLO) to prevent damage from overtemperature or insufficient supply voltage conditions. Designed for operation in extended temperature ranges from –40°C to +150°C, the device meets AEC-Q100 Grade 1 qualification standards, making it ideal for use in engine control units, battery management systems, DC-DC converters, and motor drives in automotive electronics. Its compact SO-8 package further simplifies integration into space-constrained designs while maintaining high performance and durability. The UCC27517A-Q1 also includes a dedicated enable pin that allows for precise control of the driver’s operation, enabling system-level power management strategies. With low quiescent current consumption and high noise immunity, it ensures efficient and stable performance even under demanding electrical conditions. This makes it an excellent choice for safety-critical systems requiring reliable and responsive gate driving in modern automotive power electronics.
