2.3.7 UCC27712

The UCC27712 is a 620V, high-side and low-side gate driver with 1.8A source, 2.8A sink current, targeted to drive power Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFET) or Insulated Gate Bipolar Transistors (IGBT). The recommended VDD operating voltage is 10V to 20V for IGBTs and 10V to 17V for power MOSFETs. The UCC27712 includes protection features where the outputs are held low when the inputs are left open or when the minimum input pulse width specification is not met. Interlock and dead-time functions prevent both outputs from being turned on simultaneously.
