MAX14626

High-Voltage Reverse-Input-Capable 4mA–20mA

Current Loop Protector

General Description

Beneﬁts and Features

● High Performance

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 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.

• Low On-Resistance 25Ω (typ)

• Accurate ±10% Current Limit

• +2.3V to +40V Wide Supply Voltage Range

• Low Operating Current

• Ultra-Low Temperature Coeﬃcient

● Robust Protection for Sensors

• Avoids Power Dissipation Issues Compared to

Discrete Solutions

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.

• Thermal Shutdown

• Reverse Input Protection

● Saves Space in Compact Systems

• Eliminates Need for Discrete PTC Poly Switch,

Zener Diodes, and Resistors

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.

• 3mm x 3mm, 6-Pin TDFN Package

Applications

● Industrial Current Loop Control
