To protect device and prevent the undesirable voltage transients or
brown-outs, it’s required to regulate input voltage before feeding it to
the power input of device.
There are two ways of electrical voltage regulation. One way is to
implement a power management block that harnesses battery power
during engine startup. The more effective way is to implement a power
management block with filters that further smoothes out residual spikes.
Power Management
Voltage regulation is done solely on the power management block,
which routes battery power to the ignition switch during engine
startup, while rendering conditioned output DC power to the vehicle’s
electrical parts. Please see figure below for power management.
