Description

The IRS20955 is a high voltage, high speed MOSFET driver with a floating PWM input designed for Class D audio amplifier applications.

Bi-directional current sensing detects over-current conditions during positive and negative load currents without any external shunt resistors. A built-in protection control block provides a secure protection sequence against overcurrent conditions and a programmable reset timer.

The internal deadtime generation block enables accurate gate switching and optimum deadtime setting for better audio performance, such as lower THD and lower audio noise floor.

V_{OFFSET (max)}	± 100 V
Gate driver I_o+ I_o-	1.0 A 1.2 A
Selectable deadtime	15 ns, 25 ns 35 ns, 45ns
Propagation delay	90 ns
OC protection delay	500 ns (max)
Shutdown propagation delay	250 ns (max)
