Texas Instruments High-Performance Analog UCD7230RGWT

The UCD7230 is a synchronous buck gate driver with integrated current sensing, designed for digitally controlled power stages in high-current applications. It is packaged in a QFN-20 (5 mm × 5 mm, 0.65 mm pitch) with an exposed thermal pad for thermal management. The device features dual TrueDrive™ gate drivers with 2.2-A sourcing and 3.5-A sinking capability, 10-ns typical rise/fall times, and operates up to 2 MHz. It includes a 3.3-V, 10-mA regulated output for controller power, a 48x differential current sense amplifier, and dual adjustable peak current limit protection with a latchable fault flag. Input logic levels are compatible with 3.3-V digital controllers. The part operates from -40°C to +125°C, is RoHS compliant, and uses a lead-free NIPDAU finish.
