Key Features
- 120V bootstrap voltage supports high-side gate driving in half-bridge and full-bridge topologies
- 4A peak source/sink current enables fast switching of large power MOSFETs and IGBTs
- Gated Schmitt trigger inputs provide noise immunity and prevent false triggering in high-dv/dt environments
- Dual-channel (high-side + low-side) design in compact 8-pin SOIC package reduces BOM count
- High-frequency operation suitable for resonant converters, motor drives, and DC-DC power stages
Applications
The UCC27211DDA is widely used in half-bridge and full-bridge DC-DC converters, synchronous buck regulators, and motor drive inverters where independent high-side and low-side gate control is required. Its 120V bootstrap rating makes it ideal for industrial power supplies, class-D audio amplifiers, and EV battery management systems. The device is also suited for solar inverters and UPS systems demanding reliable, high-speed MOSFET switching with robust noise rejection.

Frequently Asked Questions
What is the maximum bootstrap voltage supported by the UCC27211DDA?
The UCC27211DDA supports a maximum bootstrap voltage of 120V, allowing it to drive the high-side MOSFET gate in half-bridge topologies with bus voltages up to 120V. This makes it suitable for a wide range of industrial and automotive power conversion applications.
What peak gate drive current can the UCC27211DDA deliver?
The UCC27211DDA delivers a 4A peak source and sink current on both the high-side and low-side outputs. This high peak current capability ensures fast MOSFET switching transitions, reducing switching losses in high-frequency power converters operating above 1 MHz.
What package does the UCC27211DDA come in and what are typical applications?
The UCC27211DDA is available in an 8-pin Small Outline (SOIC-8) package. It is commonly used in half-bridge DC-DC converters, synchronous buck regulators, motor drive inverters, class-D audio amplifiers, and industrial power supplies where compact, high-performance gate driving is required.
Can the UCC27211DDA replace other half-bridge gate driver ICs?
Yes, the UCC27211DDA is pin-compatible with many standard 8-pin half-bridge gate drivers. Designers migrating from similar devices should verify bootstrap voltage rating, input logic thresholds (this device uses a gated Schmitt trigger), peak current, and propagation delay specifications to ensure compatibility with their design requirements.
