The UCC27311A is a robust gate driver designed to drive two N-channel MOSFETs in a half-bridge or synchronous buck configuration with an absolute maximum bootstrap voltage of 120V. Its 3.7A peak source and 4.5A peak sink current capability allows the UCC27311A to drive large power MOSFETs with minimized switching losses during the transition through the Miller Plateau. The switching node (HS pin) can handle negative transient voltage, which allows the high-side channel to be protected from inherent negative voltages caused by parasitic inductance and stray capacitance.
The inputs are independent of supply voltage and are able to withstand -10V and +20V absolute maximum ratings. The low-side and high-side gate drivers are matched to 4ns between the turn on and turn off of each other and are controlled throught the LI and HI input pins respectively. An on-chip 120V rated bootstrap diode eliminates the need to add discrete bootstrap diodes. Undervoltage lockout (UVLO) is provided for both the high-side and the low-side drivers which provides symmetric turn on and turn off behavior and forces the outputs low if the drive voltage is below the specified threshold.
