Typical Operating Circuit
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).
The ICs also feature programmable current-limit protec-
tion up to 4.2A. Once current reaches the threshold,
the MAX14571 turns off after the 20.7ms (typ) blanking
time and stays off during the retry period. The MAX14572
latches off after the blanking time, and the MAX14573
limits the current continuously. In addition, these devices
feature reverse current and thermal-shutdown protection.
The ICs are available in a small 14-pin TSSOP (5mm x
6.5mm) package and are specified over the extended
-40NC to +85NC temperature range.
