Half bridge mosfet gate driver

MOSFET and IGBT half bridge gate driver. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The logic input is compatible with standard CMOS or TTL outputs, down to V logic. The output drivers feature a high-pulse current buffer stage designed for minimum driver cross-Author: Infineon. It is a single chip half bridge gate driver for the N-channel power MOSFET or IGBT. The high-side (floating) section is designed to stand a voltage rail up to V. The logic inputs are CMOS/TTL compatible down to V for the easy interfacing microcontroller/DSP. The DGG, DGD and DGD are V gate drivers capable of driving N-channel MOSFETs in half-bridge configuration. Source Sink Currents (A, A DGD/5; A, A DGDG).

Description. The L is a high voltage device manufactured with the BCD™ “offline” technology. It is a single chip half bridge gate driver for the N-channel power MOSFET or IGBT. The high-side (floating) section is designed to stand a voltage rail up to V. n Half Bridge and Full Bridge Motor Control n Synchronous Step-Down Switching Regulators n Three-Phase Brushless Motor Drive n High Current Transducer Drivers n Battery-Operated Logic-Level MOSFETs + – RSENSE Ω μF LOW ESR μF IRFZ34 IRFZ34 24V 1N 10μF 1μF μF PWM 0Hz TO kHz BOOST DR BOOST T GATE DR T GATE FB T SOURCE. The gate driver in Figure 3 will differentially drive the primary of the pulse transformer, which has two windings on the secondary to drive each gate of a half bridge. An advantage of using a pulse transformer is that it does not require isolated power supplies to drive the secondary side MOSFETs.
