The MAX14626 current loop protector features a current-limit switch to prevent damage to the analog input module from sensor failure. 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. -Voltage Reverse-Input-Capable 4–20mA Current Loop Protector MAX14626
