General Description
The MAX14571/MAX14572/MAX14573 adjustable over voltage- and overcurrent-protection devices are ideal to protect systems against positive and negative input voltage faults up to Q40V and feature low 100mI (typ) RON FETs.
The overvoltage-protector (OVP) feature protects voltages between 6V and 36V, while the undervoltage-protector (UVP) feature protects voltages between 4.5V and 24V. The overvoltage-lockout (OVLO) and undervoltage-lockout (UVLO) thresholds are set using optional external resistors. The factory-preset internal OVLO threshold is 33V (typ) and the preset internal UVLO threshold is 19.2V (typ).
