SP004914370 Product details

Features & Benefits
• High accurate, scalable, DC & AC current sensing.
• Very low sensitivity error over temperature and
lifetime.
• Excellent stability of offset over temperature and
lifetime.
• High bandwidth provides fast response time and low
phase delay.
• Differential sensor principle ensures superior
magnetic stray field suppression.
• Two independent fast Over-Current Detection (OCD)
pins with configurable thresholds enable fast
protection mechanisms for power circuitry (typical
0.7μs).
• Full scale up to 31 mT for high current applications.
• Small form factor enables low insertion resistance
and less power loss.
• Configurable analog output operational modes
(fully-differential, semi-differential or
single-ended, uni- and bidirectional with or without
ratiometricity)
• Supply voltage 3.1 to 3.5V.
• Developed in accordance with ISO 26262 for safety
requirements rated up to ASIL B.
• Different package solutions for optimal system
integration in different wiring schemes.
Description
TLE4972 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 the magnetic field caused by
currents. With a full scale up to ±31mT it is possible
to measure currents up to 2,000 ampere. All
negative effects (e.g. saturation, hysteresis)
commonly known from open loop sensors using flux
concentration techniques are avoided. The sensor is
developed in accordance to functional safety
standard ISO 26262 and is equipped with internal
self-diagnostics.
Typical applications are electrical drives, on board
chargers, battery main switches, power supplies,
over-load and over-current detection in high voltage
applications.
The digitally assisted analog concept of TLE4972
offers superior stability over temperature and
lifetime thanks to the Infineon proprietary digital
stress and temperature compensation. The
differential measurement principle allows great
stray field suppression for operation in harsh
environments.
The sensor is available in two packages to support a
wide range of different system integration
scenarios.
Two separate over current detection pins (OCD)
provide a fast output signal in case the
measurement current exceeds the configured
thresholds in typical 0.7μs.
The sensor is shipped as a pre-calibrated product,
which provides an accurate performance over
temperature and stress. The TLE4972 has in-situ
calibration capability to achieve maximum accuracy
at the system level.
The high configurability enables customization for a
wide variety of applications.
