Overview
The UCC5350SBDR is a single-channel current-isolated gate driver from Texas Instruments, housed in an SOIC-8 package. It provides galvanic isolation with a 3-kVRMS rating and supports output supply voltages from 9.5 V to 33 V. The device delivers peak output currents of 5 A for both sourcing and sinking. Key electrical parameters include a maximum propagation delay of 100 ns, rise and fall times of 10 ns each, and a typical operating supply current of 1.67 mA. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Current-based capacitive coupling technology enables high-speed signal transmission across the isolation barrier.
- Integrated Miller clamp functionality suppresses false turn-on events during high dv/dt transients.
- Supports split-output configurations to optimize switching performance and reduce electromagnetic interference.
- Provides basic or reinforced insulation ratings suitable for demanding industrial applications.
Applications
- Industrial motor drives and inverters
- Solar micro-inverters and power conditioning systems
- High-frequency switched-mode power supplies
- Battery management systems requiring isolated control
Procurement Notes
Verify the specific suffix 'SBDR' corresponds to the SOIC-8 tape-and-reel packaging configuration. Confirm that the required isolation certification level (basic or reinforced) aligns with the system safety design. Ensure input voltage levels remain within the specified operational limits to maintain signal integrity and device reliability.
Selection Notes
Select this component when a single-channel driver with 5 A peak current capability is required. The current-isolation architecture offers superior common-mode transient immunity compared to optical alternatives. Consider the SOIC-8 footprint for space-constrained PCB layouts. Validate thermal dissipation requirements given the 1.21 W power dissipation specification under load.
Part Context
This part belongs to the UCC53x0 family of single-channel isolated gate drivers. The series utilizes Texas Instruments' proprietary current-coupling technology to achieve high-speed isolation without optical components. The SBDR suffix specifically denotes the reel-packaged version of the standard UCC5350 device, facilitating automated assembly processes.
Replacement Considerations
Direct substitutes within the same family include UCC5350MCDR, which shares identical electrical characteristics but differs in packaging format. Verify pinout compatibility and isolation voltage ratings before substituting with other isolated gate driver families.
