Requirements
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.
