Automotive 3-A, 120-V half bridge gate driver with 8-V UVLO and CMOS inputs

The UCC27200-Q1 high frequency N-channel MOSFET drivers includes a 120V bootstrap diode and high-side and low-side drivers with independent inputs for maximum control flexibility. This allows for N-channel MOSFET control in half-bridge, full-bridge, two-switch forward, and active-clamp forward converters. The low-side and the high-side gate drivers are independently controlled and matched to 1ns between the turnon and turnoff of each other.

An on-chip bootstrap diode eliminates the external discrete diodes. Undervoltage lockout is provided for both the high-side and the low-side drivers, forcing the outputs low if the drive voltage is below the specified threshold.

The UCC27200-Q1 has high-noise-immune CMOS input thresholds.

The device is offered in the 8-pin SO PowerPAD™ (DDA) package.
