High-Current Overvoltage Protector with Adjustable OVLO
MAX14653/MAX14654/
MAX14655/MAX14717
High-Current Overvoltage Protectors
with Adjustable OVLO
General Description
The MAX14653/MAX14654/MAX14655/MAX14717 over-voltage protection devices feature a low 38mΩ (typ) RON internal FET and protect low-voltage systems against
voltage faults up to +28VDC. An internal clamp also pro-
tects the devices from surges up to +80V. When the input
voltage exceeds the overvoltage threshold, the internal
FET is turned off to prevent damage to the protected
downstream components.
The overvoltage protection threshold can be adjusted with optional external resistors to any voltage between 4V and
20V. With the OVLO input set below the external OVLO
select voltage, the MAX14653/MAX14654/MAX14655/MAX14717 automatically choose the accurate internal trip thresholds. The internal overvoltage thresholds (OVLO) are preset to 15.5V typical (MAX14653), 6.8V typical (MAX14654/MAX14717), or 5.825V typical (MAX14655).
The devices feature an open-drain ACOK output indi-cating a stable supply between minimum supply volt-
age and VOVLO. The MAX14653/MAX14654/MAX14655/
MAX14717 are also protected against overcurrent events by an internal thermal shutdown.
The MAX14653/MAX14654/MAX14655/MAX14717 are
offered in a small 12-bump WLP package and operate
over the -40ºC to +85ºC extended temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
