Product Brief

Applications

Reliable Wheel Speed Sensing in

automotive applications

TLE 4941plusC

Diﬀerential Hall IC for Wheel Speed Sensing

Anti-lock Braking System (ABS)

Electronic Stability Program (ESP)

Automatic Transmissions

TLE 4941plusC, a diﬀerential Hall sensor for measuring magnetically the car´s

wheel speed, is the latest oﬀspring of the extremely successful TLE 4941 family,

based on Inﬁneon’s most recent sensor technologies for front- and backend.

Designed as drop-in replacement the TLE 4941plusC is, as its predecessors, a

single chip solution combining Hall sensor elements and both analogue and

digital signal processing in one single chip. Its diﬀerential principle makes it

immune to any kind of undesired magnetic ﬁelds and disturbances. The Hall

element distance has been downsized to 2 mm to be also ﬁt for extremely

small encoders. Several product improvements, both electrical and magnetic,

have been put in place, such as an accelerated calibration during start-up pha-

se and higher load dump robustness. The formerly optional ﬁrst-edge-detection,

a feature for quick start-up, providing a reliable output signal even before cali-

bration is fully completed, has now become standard.

Features

Two-wire current interface: Minimizes

wiring

Dynamic self-calibration principle:

Compensates oﬀsets

Single chip solution: Ensures outstan-

ding reliability

High sensitivity: Can be used for large

airgap applications

South and north pole pre-induction

possible: Works for both encoders

and tonewheels

TLE 4941plusC has a standard 2-wire current interface, high ESD robustness

and works in the wide temperature range present in the harsh automotive

environment. Magnetic and device oﬀsets are cancelled by a sophisticated self-

calibration algorithm immediately after start-up.

The TLE 4941plusC is an extremely robust product due to Inﬁneon’s high quality

standards as experienced automotive semiconductor supplier. After several

hundred million units sold, Inﬁneon’s active wheel speed sensors have largely

proven to be the perfect match for wheel speed sensing in all aspects of functio-

nality, robustness and ﬂexibility.

High resistance to piezo eﬀects: Suits

sensor overmolding wide operating

temperature range

C type with 1.8 nF overmolded capa-

citor: Enhances EMC & microbreak

resistance, without any external

components
