UCC27517AQDBVRQ1 Description

Short technical summary and product information.

The Texas Instruments UCC27517AQDBVRQ1 is a high-speed, single-channel, low-side gate driver. It is designed to drive GaNFET, IGBT, and N-Channel MOSFET power switches with a peak output current of 4A.

 

This device operates from a wide input supply voltage range of 4.5V to 18V and features a typical undervoltage lockout of 4V. The UCC27517AQDBVRQ1 supports both inverting and non-inverting input logic, with CMOS and TTL compatible input thresholds. It offers fast switching characteristics, including a typical rise time of 9ns and a fall time of 7ns, with a propagation delay of 13ns.

 

Packaged in a compact SOT-23-5 (SC-74A, SOT-753) surface-mount case, this gate driver is suitable for applications requiring efficient power switching. The operating temperature range is -40°C to 150°C (TJ), making it robust for various environmental conditions. It is qualified for automotive applications.

 

Key electrical specifications include a 4A symmetrical drive capability, ability to handle negative input voltages up to -5V, and hysteretic logic thresholds for high noise immunity. The outputs are held low during VDD UVLO, ensuring glitch-free operation during power up and power down.
