Description

TLE4971 is a high precision miniature coreless

magnetic current sensor for AC and DC

measurements with analog interface and two fast

over-current detection outputs.

Infineon's well-established and robust monolithic

Hall technology enables accurate and highly linear

measurement of currents with a full scale up to

±120A. The sensor is equipped with internal selfdiagnostic

feature.

Typical applications are Onboard Chargers as well

as any kind of Drives.

The differential measurement principle allows

great stray field suppression for operation in

harsh environments.

Two separate interface pins (OCD) provide a fast

output signal in case a current exceeds a pre-set

threshold.

The sensor is shipped as a fully calibrated product

without requiring any customer end-of-line

calibration.

All user-programmable parameters such as OCD

thresholds, blanking times and output configuration

modes are stored in an embedded EEPROM

memory.
