UCC27210D

Gate Driver Overview

The UCC27210D is a high-frequency half-bridge MOSFET gate driver manufactured by Texas Instruments in an 8-pin SOIC package. It features independent high-side and low-side drivers with a maximum bootstrap voltage of 120 V DC. The device delivers 4 A peak source and sink output currents, utilizing 0.9 Ω internal pull-up and pull-down resistors to minimize switching losses during Miller plateau transitions. It operates within an 8 V to 17 V supply range (absolute maximum 20 V) and supports input voltages from -10 V to 20 V, independent of the power supply. Typical propagation delay is 18 ns with 2 ns matching.

Gate Driver Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-8 package variant when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified 8 V to 17 V operating voltage range. Validate thermal performance requirements for the surface-mount installation style.

Gate Driver Selection Notes

Select this component for applications requiring robust drive current for large power MOSFETs. The wide input voltage tolerance simplifies interface design with various control logic levels. Consider the SOIC-8 package constraints for PCB layout and thermal dissipation. Verify that the 120 V bootstrap rating meets the circuit's maximum node voltage requirements.
