Key Applications

? Input Voltage and Output Overcurrent Protections:

The MAX17616/MAX17616A interrupts load current and

disconnects the output from the input in input voltage

faults and output overcurrent faults.

? Loss of Ground Protection:

The MAX17616/MAX17616A interrupts load current and

disconnects the output from the input in a Loss of

Ground event, such as when the single-fault safety fuse

on its ground path opens up.

? Surge Protection:

The MAX17616A features an output voltage limiting

regulation during transient surges in input voltage to

protect connected loads from short-duration input

voltage surge events.
