Texas Instruments UCC27710 620V Gate Drivers With Interlock

Texas Instruments UCC27710 620V Gate Drivers With Interlock are designed to drive power MOSFETs or IGBTs, with both a High-Side and Low-Side 0.5A source gate driver. The UCC27710 is developed with TI's state-of-the-art high-voltage technology offering robust drive and exceptional noise and transient immunity. VDD recommended operating voltage for IGBTs is 10V to 20V and 10V to 17V for power MOSFETs. An excellent protection feature includes interlock and deadtime functions, which prevents both outputs from being turned on simultaneously. Additionally, the outputs are held low when the inputs are left open or when the minimum input pulse width specification is not met. The device also provides UVLO protection for the VDD and HB bias supply with an accepted wide-range bias supply range from 10V to 20V. The Texas Instruments UCC27710 includes one ground-referenced channel (LO) and one floating channel (HO), designed for operating with bootstrap or isolated power supplies.
