Automotive load dump and reverse voltage protection
The MAX16127TC+T is a load dump and reverse voltage protection IC from Analog Devices, designed to safeguard downstream electronics from the high-energy transients that occur when a battery is disconnected while the alternator is charging — a load dump event that can push the 12V bus well above 30V for hundreds of milliseconds.
Quiescent current and standby budget
Drawing only 224µA from the supply, the MAX16127TC+T adds negligible load to the battery in key-off standby — a consideration for ECUs that must remain powered for wake-on-CAN or RTC retention without draining the battery over a long parked period.
