The MAX6397 evaluation kit (EV kit) demonstrates a
high-voltage overvoltage protection circuit for automo-
tive applications that must survive load dump and high-
voltage transient conditions. This EV kit is a fully assem-
bled and tested surface-mount board.
The EV kit supports high-output currents up to 5A, runs
at voltages up to 72V, and can withstand temperatures
ranging from -40°C to +105°C. Two alternate voltage
inputs implement two different schemes for reverse-bat-
tery protection. Connections to the on-chip linear regu-
lator, capable of driving 100mA, and the power-good
(POK) signal are also provided.
