TDA75610SLV

Battery transitions management

7.1

Low voltage operation (“start stop”)

The most recent OEM specifications require automatic stop of car engine at traffic light, in

order to reduce emissions of polluting substances. The TDA75610SLV, thanks to its

innovating design, allows to go on playing sound when battery falls down to 6/7V during

such conditions, without producing pop noise. The maximum system power will be reduced

accordingly.

Supported battery cranking curves are shown below, indicating the shape and duration of

allowed battery transitions.

Figure 34. Worst case battery cranking curve sample 1

V1 = 12 V; V2 = 6 V; V3 = 7 V; V4 = 8 V

t1 = 2 ms; t2 = 50 ms; t3 = 5 ms; t4 = 300 ms; t5 =10 ms; t6 = 1 s; t7 = 2 ms

Figure 35. Worst case battery cranking curve sample 2

V1 = 12 V; V2 = 6 V; V3 = 7 V

t1 = 2 ms; t2 = 5 ms; t3 = 15 ms; t5 = 1 s; t6 = 50 ms
