Silicon Labs SI8244BB-D-IS1

Description
The Si824x isolated driver family combines two isolated drivers in a single package.
The Si8241/44 are highside/lowside drivers specifically targeted at highpower (>30 W) audio applications.
Versions with peak output currents of 0.5 A (SI8241) and 4.0 A (Si8244) are available.
All drivers operate with a maximum supply voltage of 24 V.
Based on Silicon Labs' proprietary isolation technology, the Si824x audio drivers incorporate inputtooutput and outputtooutput isolation, which enables leveltranslation of signals without additional external circuits as well as use of bipolar supply voltage up to 1750 V.
The Si824x audio drivers feature an integrated deadtime generator that provides highly precise control for achieving optimal THD.
These products also have overlap protection that safeguards against shootthrough current damage.
The CMOSbased design also provides robust immunity from latchup and highvoltage transients.
The extremely low propagation delays enable faster modulation frequencies for an enhanced audio experience.
The TTL level compatible inputs with >400 mV hysteresis are available in PWM input configuration; other options include UVLO levels of 8 V or 10 V.
These products are available in narrow body SOIC packages.
