The UCC27284 is a high-voltage gate driver designed to drive both the high-side and the low-side N-channel FETs in a synchronous buck or a half-bridge configuration. The two outputs are independently controlled with two TTL-compatible input signals. The device can also work with CMOS type control signals at its inputs as long as signals meet turn-on and turn-off threshold specifications of the UCC27284. The floating high-side driver is capable of working with HS voltage up to 100 V with respect to VSS. A 100 V bootstrap diode is integrated in the UCC27284 device to charge high-side gate drive bootstrap capacitor. A robust level shifter operates at high speed while consuming low power and provides clean level transitions from the control logic to the high-side gate driver. Undervoltage lockout (UVLO) is provided on both the low-side and the high-side power rails. EN pin is provided (in DRC packaged parts) to enable or disable the driver.
