8.2.2 Automotive Applications
The TPS7A16-Q1 maximum input voltage of 60 V makes the device designed for use in automotive applications where high-voltage transients are present.
Events such as load-dump overvoltage (where the battery is disconnected while the alternator is providing current to a load) can cause voltage spikes from 25 V to 60 V. To prevent any damage to sensitive circuitry, local transient voltage suppressors can be used to cap voltage spikes to lower, more manageable voltages.
The TPS7A16-Q1 can be used to simplify and lower costs in such cases. The very high voltage range allows this regulator not only to withstand the voltages coming out of these local transient voltage suppressors, but even replace them, thus lowering system cost and complexity.
