nn AEC-Q100 Qualified for Automotive Applications n n n n n n APPLICATIONS n n The LTC®4365 protects applications where power supply
input voltages may be too high, too low or even negative.
It does this by controlling the gate voltages of a pair of
external N-channel MOSFETs to ensure that the output
stays within a safe operating range.The LTC4365 can
withstand voltages between –40V and 60V and has an …
