D类精密死区时间发生器音频驱动Si824x
分享资料个
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 leveltranslation 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 deadtime generator that provides highly precise control for achieving optimal THD. These products also have overlap protection that safeguards against shootthrough 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.
