The IRS20124SPBF 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. In order to maximize other audio performance characteristics, all switching times are designed for immunity from external disturbances such as VCC perturbation and incoming switching noise on the DT pin. Logic inputs are compatible with LSTTL output or standard CMOS down to 3V without speed degradation. The output driver features high current buffers capable of sourcing 1A and sinking 1.2A. Internal delays are optimized to achieve minimal dead-time variations. Proprietary HVIC and latch immune CMOS technologies guarantee operation down to -4Vs, providing outstanding capabilities of latch and surge immunities with rugged monolithic construction.
Integrated dead-time generation and bi-directional over-current sensing simplify design
