General Description
The MAX14653/MAX14654/MAX14655 overvoltage pro-
tection devices feature a low 38mΩ (typ) R
FET and protect low-voltage systems against voltage
faults up to +28V
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 down-
stream 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
automatically choose the accurate internal trip thresholds.
The internal overvoltage thresholds (OVLO) are preset to
15.5V typical (MAX14653), 6.8V typical (MAX14654), or
5.825V typical (MAX14655). The devices feature an open-
drain ACOK output indicating a stable supply between
minimum supply voltage and V
MAX14654/MAX14655 are also protected against over-
current events by an internal thermal shutdown.
The MAX14653/MAX14654/MAX14655 are offered in a
small 12-bump WLP package and operate over the -40ºC
to +85ºC extended temperature range.
