MAX14626
High-Voltage Reverse-Input-Capable 4–20mA
Current Loop Protector
General Description
The MAX14626 current loop protector features a current-
limit switch to prevent damage to the sensor devices due
to faulty current loop conditions. The current-limit switch
features a 25I (typ) on-resistance and operates from a
+2.3V to +36V input voltage range. The accurate current
limit is set to 30mA, making the part ideal for protecting
the sensor reading devices.
The MAX14626 handles an overcurrent event in a con-
tinuous current-limit mode. Additional safety features
include thermal shutdown to prevent overheating and
reverse-input blocking to protect from being reverse con-
nected into the sensor.
The device is available in a tiny 6-pin (3mm x 3mm),
TDFN exposed pad package and is specified over the
-40NC to +85NC extended temperature range.
