Description
The Si824x isolated driver family combines two isolated drivers in a single
package. The Si8241/44 are high-side/low-side drivers specifically targeted at
high-power (>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 input-to-output and output-to-output isolation, which enables level-
translation of signals without additional external circuits as well as use of bipolar
supply voltage up to ±750 V. The Si824x audio drivers feature an integrated dead-
time generator that provides highly precise control for achieving optimal THD.
These products also have overlap protection that safeguards against shoot-
through current damage. The CMOS-based design also provides robust immunity
from latch-up and high-voltage 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.
