BM78在额定电压3.3V下运行是否正常

我们目前正在使用BM77在一个应用程序，它是伟大的工作。然而，存在一个问题，即该设备现在NRND。BM78是一种在我们的应用中会起作用的替代品，但问题是它的最小输入电压规格。BM77具有在3.2V指定的最小输入电压，并且我们在3.3V的电压下操作它（不是很大的净空，但是在我们的设计中，电压不应该下降到3.2V）。但是BM78的最低输入电压规格为3.3V。这意味着我们将没有任何公差或倾角的净空。我有BM78的评估板，它也在3.3V（实际上是BAtiXIN引脚3.95V）上运行，并且似乎运行良好。我的问题是，BM78在额定电压3.3V下运行是否正常，并期望它在该电压下工作小偏差？

    We are currently using the BM77 in an application and it is working great.  However, there is a problem in that the device is now NRND.  The BM78 is a drop in replacement that will work in our application, but the issue is its minimum input voltage specification.

The BM77 has a minimum input voltage specified at 3.2V, and we operate it at a voltage of 3.3V (not a lot of headroom, but in our design the voltage should never dip down to 3.2V).  But the BM78 has a minimum input voltage specification of 3.3V.  this means we would have no headroom for any tolerances or dip-outs.

I have the evaluation board for the BM78 and it also operates on 3.3V (3.295V to the BAT_IN pin actually), and it seems to operate fine.  My question is, is it ok to operate the BM78 at a nominal voltage of 3.3V and expect it to operate with small deviations in that voltage?
