Texas Instruments UCC27710DR

The UCC27710 isa 620-V high-side and low-side gate driver with 0.5-A source, 1.0-A sink current, targeted to drivepower MOSFETs or IGBTs.

The recommended VDD operating voltage is 10-V to 20-V for IGBT’s and 10-V to 17-V forpower MOSFETs.

The UCC27710 includes protection features where the outputs are held low when the inputsare left open or when the minimum input pulse width specification is not met. Interlock anddeadtime functions prevent both outputs from being turned on simultaneously. In addition, thedevice accepts a wide range bias supply range from 10 V to 20 V, and offers UVLO protection forboth the VDD and HB bias supply.

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

The device consists of one ground-referenced channel (LO) and one floating channel (HO)which is designed for operating with bootstrap or isolated power supplies. The device features fastpropagation delays and excellent delay matching between both channels. On the UCC27710, eachchannel is controlled by its respective input pins, HI and LI.
