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.
