2.5-A/5-A single-channel gate driver with 8-V UVLO, 35-V VDD, CMOS inputs, and split outputs

UCC27532DBVR General Description

The UCC27532DBVR is a single-channel, high-speed gate driver that excels in effectively driving MOSFET and IGBT power switches. With its peak current capability of up to 2.5A source and 5A sink, the driver offers asymmetrical drive with strong sink capability, enhancing immunity against parasitic Miller turn-on effect. Its split-output configuration allows for independent control of switching slew rates, offering flexibility to the user. Additionally, the rail-to-rail drive capability and short propagation delay of typically 17ns ensure precise and efficient operation. The CMOS input threshold and EN pin with fixed TTL compatible threshold further contribute to the device's versatility and reliability. The under voltage lockout function on the VDD pin provides an added layer of protection by holding the output low until the supply voltage is within the operating range. Enclosed in a 6-pin standard SOT-23 (DBV) package, the UCC27532DBVR operates effectively over a wide temperature range, from -40°C to 140°C, making it suitable for various application environments
