Overview

Product Specification TDGD27x Data Sheet Isolated Gate Drivers October 2021 Single/Dual 4-Amp Isolated Gate Driver with High Transient (dV/dt) Immunity The TDGD27x isolators are ideal for driving power switches used in a wide variety of power supply, inverter, and motor control applications.

The TDGD27x isolated gate drivers utilize a proprietary silicon isolation technology, supporting up to 2.5 kVRMS withstand voltage and fast 60 ns propagation times.

This technology enables industry leading, common-mode transient immunity (CMTI), tight timing specifications, reduced variation with temperature and age, better part-to-part matching, and extremely high reliability.

Key Features

  • such as separate pull-up/down outputs, driver shutdown on UVLO (Undervoltage Lockout) fault, and precise dead-time programmability. The TDGD27x series offers longer service life and dramatically higher reliability compared to opto-coupled gate drivers. Driver outputs can be grounded to the same or separate grounds or connected to a positive or negative voltage. TTL-level compatible inputs with >400 mV hysteresis is available in individual control input (TDGD271) or PWM input (TDGD274) configurat.
