1Product Description

The TLE4922 is an active mono cell Hall sensor suited to detect motion

and position of ferromagnetic and permanent magnet structures. An

additional self-calibration module has been implemented to achieve

optimum accuracy during normal running operation.

1.1 Target Application

The TLE4922 is a speed sensor especially optimized for small engine (2-

and 3 wheeler) applications.

•Crankshaft speed and position sensing

•Transmission speed on output shaft

•Speedometer application

Excellent sensitivity and accuracy combined with its wide operational

temperature range makes the sensor ideally suited for harsh

environments.

1.2 Key Features and Benefits

• Twist independent mounting (TIM) “enables one sensor fits all”

• Small thin package (PG-SSO-4-1)

• Protected against harsh environment due to

–Short-circuit current limitation at the output

–Over temperature shutdown at the output and

–Reverse voltage protection

• Supreme performance due to adaptive symmetrical hysteresis /

threshold

•Independent of back bias magnet polarity due to ±400mT full

scale range

• Enhanced EMC & ESD robustness - ESD : ±3kV HBM

• Wide operating temperature range - Tjunction: -40 °C - 155 °C

•True zero speed up to 8kHz signal frequency

• Enabling Low Power Application: Idd = 5mA at Vdd = 9V

• Large operating voltage range of 4.5V up to 18V

• Robustness against wheel run outs enables to sense broad range

of wheels

2.5 Electromagnetic Compatibility (EMC)

The TLE4922 is characterized according to the IC level EMC requirements described in the “Generic IC EMC Test

Specification” Version 1.2 from 20071). Additionally, component level EMC characterizations according to ISO 7637-

2:2011, ISO 7637-3:2007 and ISO 16750-2:2010 regarding pulse immunity and CISPR 25 (2009-01) Ed. 3.0 regarding

conducted emissions are performed.

Figure 1-1 on first page outlines all needed external components to operate the DUT under application conditions. They

are treated as inherent part of the DUT during component level EMC characterizations.

Note: Characterisation of Electro Magnetic Compatibility (EMC) are carried out on sample base of one qualification lot. Not all specification

parameters are monitored during EMC exposure. Only key parameters e.g. switching current and duty cycle are monitored.

Specification

2.8 Application

Basic functionality

The TLE4922 is a mono-cell Hall sensor with analog to digital converter and full digital signal processing for detecting the

magnetic field crossing of the threshold levels. A chopped Hall probe is used to mimic the offset and has advantages for

0-Hz feature. Figure 2-1 shows the basic functionality of TLE4922.

Unique Feature: Polarity of Pre Induction

The back bias magnet can be mounted in both directions to TLE4922 without any difference in performance. One polarity

results in switching the output to “LOW” when passing a tooth and to “HIGH” when passing a notch, whereas the other

polarity of back-bias magnet will switch the output to “HIGH” when passing a tooth and to “LOW” when passing a notch.

Figure 2-4 Changing polarity of back bias magnet will change the polarity of TLE4922 output

Start-Up and Running Mode

In Start-Up-Mode the TLE4922 starts with output at “HIGH” and stays there until a first minimum in magnetic field is

detected after start-up time. Calibrated mode is reached after a maximum of four output transitions (The offset

compensation algorithm is considering 4 teeth for averaging). At the 4th falling edge full accuracy on output signal is

reached. These first transitions are determined by the detection of magnetic signal maxima and minima. Output

transitions in running phase are determined by the hidden adaptive hysteresis algorithm.

Application circuit

Figure 1-1 on page one shows an option of an application circuit. The resistor RS is recommended due to reason of EMC.

The resistor RL has to be at a value to match the applied VECU to keep IQ limited to the operating range of maximal 8.8mA.

e.g.: VLOAD = 9V: IQ = 9V/1200 Ω = 7.5mA

Consideration on RthJA

The Rth is modified by attaching a back-bias magnet or doing molding at the customer. There is dependency on the

attached wires: The thicker the attached wire the smaller the value of Rth. It depends on ambient condition: When one

end of the module is cooled in oil or through air-flow the RthJA will decrease.

Global run out

Due to averaging, global run out is depending on the number of teeth. The wheel in Chapter 2.6 allows a global run out

of 0.8mm. Wheels with equal or more than 8 teeth are capable of up to 0.5mm global run out.
