Data Sheet No. PD60276 Not recommended for new designs. Please use IRS20955. IRS20954SPBF Protected Digital Audio Driver Features Floating PWM input enables easy half bridge implementation Integrated programmable bi-directional over-current protection with self-reset function Programmable compensated preset deadtime for improved THD performances High noise immunity ±100 V high voltage ratings deliver up to 500 W output power 3.3 V / 5 V logic compatible input Operates up to 800 kHz Ro HS compliant Product Summary VOFFSET (max) Gate driver Selectable Deadtime Propagation delay OC protection delay Io+ Io - ± 100 V 1.0 A 1.2 A 15 ns, 25 ns, 35ns, 45 ns 90 ns 1 µs (max) Description The IRS2 0954 is a high voltage, high spe ed M OSFET drive r with floating PWM input, spe cially desi gned for Cla ss D au dio amplifier ap plications. The bi-di rectional cu rrent sensi ng requires no external shunt resistors. It can ca pture over-current conditions at either positive or negative load current direction. A built-in control block p rovides secure prote ction sequence against over-current conditions, including a programmable reset timer. The internal de adtime gen eration blo ck provide s accurate gat e swit ch timing and en ables optim um deadtime settings for b etter audio performances, such as T HD and a udio noise floor.
