Advanced battery management (hybrid vehicles)

In addition to compatibility with low Vbatt, the STPA002 is able to sustain upwards fast

battery transitions without causing unwanted audible effects, like pop noise, and without any

sound interruption thanks to the innovative circuit topology. In fact, in hybrid vehicles, the

engine ignition causes a fast increase of battery voltage which can reach 16 V in less than

10 ms.
