Product Brief

TLE5027C

Highly accurate and sensitive diﬀerential

speed sensor with

direction detection for automotive powertrain and industrial applications

Features

The TLE5027 uses the giant magneto resistive (GMR) eﬀect, which is by a factor >10

more sensitive compared to the Hall-eﬀect. The TLE5027 detects the motion and

position of ferromagnetic magnet structures by measuring the change of the magnetic

ﬁeld induced by this structure, which can be a magnetic encoder wheel, ferromagnetic

gear wheel or any similar structure. In case of any non-encoder based application like

gear wheels the magnetic ﬁeld is generated by applying a specially optimized back

bias magnet to the sensor. As the GMR sensor measures the in plane components of

the magnetic ﬁeld the sensor switches in phase with the edges of a tooth/gap pair of

a gear wheel or north/south pole pair of a magnetic encoder. The very high sensitivity

of the GMR eﬀect enables the TLE5027 to measure very large airgaps with encoder

wheels or be back biased with excellent airgap performance using a low-cost ferrite

material for the magnet.

ꢀExcellent sensitivity

ꢀHigh jitter performance

ꢀDirection detection

ꢀHidden adaptive algorithm

ꢀVery large operating airgaps

ꢀAdvanced performance by

dynamic self calibration

principle

ꢀVery low current consumption

ꢀ3-wire PWM voltage interface

ꢀWide operating temperature

ranges of -40°C ≤ T_j≤ +175°C

ꢀReverse voltage protection

at V_s-pin

The sensor has a fast start up time and the sensor switches with its hidden adaptive

hysteresis algorithm, which ensures high accuracy over airgap jumps, vibrations, run-

out events ,etc. Within the ﬁrst 3 magnetic edges after start up the sensor provides the

direction information, which is given as pulse width modulated output.

ꢀHigh ESD robustness

ꢀModule style package with two

integrated capacitors:

TLE5027 is well suited for harsh environmental conditions prevalent in automotive or

certain industrial applications by its wide temperature range as well as high ESD and

EMC robustness. In addition the TLE5027 provides the beneﬁt of a very low current

consumption. With its features the TLE5027C is ideal for applications like today’s crank-

shaft or transmission speed sensing in automotive or similar industrial applications.

– 4.7nF between Q and GND

– 47nF between V_sand GND:

Required for micro cuts in

power supply and optimal
