MAX14626

MAX14626 EVALUATION KIT AVAILABLE High-Voltage Reverse-Input-Capable 4–20mA Current Loop Protector General Description The MAX14626 current loop protector features a currentlimit switch to prevent damage to the sensor devices due to faulty current loop conditions. The current-limit switch features a 25Ω (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 continuous current-limit mode. Additional safety features include thermal shutdown to prevent overheating and reverse-input blocking to protect from being reverse connected into the sensor. The device is available in a tiny 6-pin (3mm x 3mm), TDFN exposed pad package and is specified over the -40°C to +85°C extended temperature range.
