Abstract

This application note focuses on half-bridge gate drivers from Texas Instruments with single input, enable, adjustable dead time, and integrated bootstrap diode features and relevant applications such as appliances and motor drives. Gate drivers with single input or adjustable dead time features can help simplify design complexity by requiring less microcontroller resources. These devices can also help make gate driver designs more cost effective by lowering external component count. Table 4-1 lists a summary comparison between features of the devices discussed in this application note.
