General Description
The MAX14606/MAX14607 overvoltage protection devic-
es feature low 54mI (typ) on-resistance (R
FETs and protect low-voltage systems against voltage
faults up to +36V. When the input voltage exceeds the
overvoltage threshold, the internal FET is turned off to
prevent damage to the protected components.
The devices automatically choose the accurate internal
trip thresholds. The internal OVLO are preset to typical
5.87V (MAX14606) or 6.8V (MAX14607).
The MAX14606/MAX14607 feature reverse bias blocking
capability. Unlike other overvoltage protectors, when the
MAX14606 /MAX14607 are disabled, the voltage applied to
OUT does not feed back into IN. These devices also feature
thermal shutdown to protect against overcurrent events.
The MAX14606/MAX14607 are specified over the extend-
ed -40NC to +85NC temperature range, and are available
in 9-bump WLP packages.
