There are a wide variety of half bridge gate driver IC’s available. These offer high and low transistor gate driving functionality compressed into small packages to limit PCB size and complexity. Most of them require a bootstrap capacitor which means that they have limitations to the combined PWM frequency and duty cycle (due to capacitor charge time, leakage currents, gate currents, and drain currents). They also need to be reviewed for acceptable delay characteristics. However, they offer a cheap and fast solution for most systems that have fixed output or limited variable outputs.
