Advanced battery management (hybrid vehicles)

In hybrid vehicles, the engine ignition causes a fast increase of battery voltage which can

reach 16 V in less than 10 ms. In addition to compatibility with low Vbatt, STPA008 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.
