Automotive 12-V/24-V Battery Input Protection Reference Design
Description
Automotive battery power supply lines are prone to transients while running the system. Typical protections required are overvoltage: overload: reverse polarity and jump start. During the life of a vehicle: the alternator may be replaced with a non-OEM part. The after-market alternator may have different or no load dump protection which could lead to damaging the electronic control unit (ECU). This reference design provides protection to handle these potential unsuppressed load dump pulses (12 V and 24 V) with hardware control. Class-A operation may be attained during unsuppressed load-dump pulses.
Features
- Wide-input protection voltage rangeScalable to multiple battery topologies (12 V: 24 V and 48 V)Configurable options to support Class-A operation during unsuppressed load-dump pulsesCompliance to ISO7637-2 and ISO16750-2
