Description

The IRS20124STRPBF is a high voltage, high speed power MOSFET driver with internal deadtime 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 deadtime 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 3.0 V without speed degradation. The output drivers feature high current buffers capable of sourcing 1.0 A and sinking 1.2 A. Internal delays are optimized to achieve minimal deadtime variations. Proprietary HVIC and latch immune CMOS technologies guarantee operation down to Vs= –4 V, providing outstanding capabilities of latch and surge immunities with rugged monolithic construction. IRS20124STRPBF Features • 200 V high voltage ratings deliver up to 1000 W output power in Class D audio amplifier applications• Integrated deadtime generation and bi-directional over-current sensing simplify design• Programmable compensated preset deadtime for improved THD performances over temperature• High noise immunity• Shutdown function protects devices from overload conditions• Operates up to 1 MHz• 3.3 V/5 V logic compatible input
