The MAX14527/MAX14528 overvoltage protection
devices feature a low 100mΩ (typ) R
and protect low-voltage systems against voltage faults
up to +28V. When the input voltage exceeds the over-
voltage threshold, the internal FET is turned off to pre-
vent damage to the protected components.
The overvoltage protection threshold can be adjusted
with optional external resistors to any voltage between
4V and 8V. With the OVLO input set below the external
OVLO select voltage, the MAX14527/MAX14528 auto-
matically choose the internal ±2.5% accurate trip
thresholds. The internal overvoltage thresholds (OVLO)
are preset to 5.75V typical (MAX14527) or 6.76V typical
(MAX14528). The MAX14527/MAX14528 are also
protected against overcurrent events with an internal
thermal shutdown.
The MAX14527/MAX14528 are offered in a small, 8-pin
TDFN-EP package and operate over the -40°C to
+85°C extended temperature range.
