The MIC4478, MIC4479, and MIC4480 are low-side dual MOSFET drivers are designed to switch N-channel enhancement type MOSFETs from TTL-compatible control signals for low-side switch applications. The MIC4478 is dual non-inverting, the MIC4479 is dual inverting, and the MIC4480 is complimentary non-inverting and inverting. These drivers feature short delays and high peak currents to produce precise edges and rapid rise and fall times.The MIC4478/4479/4480 are powered from a +4.5V to +32V supply voltage. The on-state gate drive output voltage is approximately equal to the supply voltage (no internal regulators or clamps).In a low-side configuration, the drivers can control a MOSFET that switches any voltage up to the rating of the MOSFET. The MIC4478/4479/4480 are available in the 8-lead SOIC (ePAD and non-ePAD) package and are rated for the –40°C to +125°C ambient temperature range.

高通的QCC304x及后续的芯片支持HybridANC,包含FFMIC和FBMIC。其中FFMIC可以与2-CVC中的副MIC共用同一个MIC,可以是数字MIC或者模拟MIC。但是如果是模拟MIC的话,因为ANC与CVC会共用FFMIC的模拟增益。
在很多应用场合,要用到多MIC设计,比如AI语音识别,就要用到多个硅麦的设计,以提高语音识别的精准度,本人曾做过两个这样的项目,下面分享下设计心得,看到这篇文章的朋友如果觉得有所帮助的话,记得
本文验证QCC3026在2-MIC CVC下,如果调换两个MIC的位置,即用右MIC做主,左MIC做从,是否具有可行性。 测试工具 MDE:MDE_WIN_2.3.2.126 Toolkit
