UCC27712 High-Side Low-Side Gate Driver IC. || U27712 IC High-Side Low-Side Gate Driver SMD IC.

UCC27712 620-V, 1.8-A, 2.8-A High-Side Low-Side Gate Driver with Interlock.The UCC27712 is a 620-V high-side and low-side gate driver with 1.8-A source, 2.8-A sink current, targeted to drive power MOSFETs or IGBTs.

The recommended VDD operating voltage is 10-V to 20-V for IGBT's and 10-V to 17-V 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 deadtime functions prevent both outputs from being turned on simultaneously. In addition, the device accepts a wide range bias supply range and offers UVLO protection for both the VDD and HB bias supply.

Developed with TI's state of the art high-voltage device technology, the device features robust drive with excellent noise and transient immunity including large negative voltage tolerance on its inputs, high dV/dt tolerance, wide negative transient safe operating area (NTSOA) on the switch node (HS), and interlock.
