Product Summary

The IRS20124STRPBF is a high voltage, high speed power MOSFET driver with internal dead-time and shutdown functions specially designed for Class D audio amplifier applications. The internal dead time generation block provides accurate gate switch timing and enables tight dead-time settings for better THD performances. The IRS20124STRPBF is designed for immunity from external disturbances such as VCC perturbation and incoming switching noise on the DT pin.
