Functional Description
2 Functional Description
This three dimensional Hall effect sensor can be configured by the microcontroller. The measurement data is
provided in digital format to the microcontroller. The microcontroller is the master and the sensor is the slave.
2.1 General
Description of the Block diagram and its functions.
Figure 1 Block Diagram
The IC consists of three main functional units containing the following building blocks:
• The power mode control system, containing a low-power oscillator, basic biasing, accurate restart,
undervoltage detection and a fast oscillator.
• The sensing unit, which contains the HALL biasing, HALL probes with multiplexers and successive tracking
ADC, as well as a temperature sensor is implemented.
•The I2C interface, containing the register files and I/O pads
2.1.1 Power mode control
The power mode control provides the power distribution in the IC, a power-on reset function and a specialized
low-power oscillator as the clock source. It also manages the start-up behavior.
• On start-up, this unit:
– activates the biasing, provides an accurate reset detector and fast oscillator
– sensor enters low power mode and can be configured via I2C interface
• After re-configuration, a measurement cycle is performed, which consists of the following steps:
– activating internal biasing, checking for the restart condition and providing the fast oscillator
– HALL biasing
– measuring the three HALL probe channels sequentially (including the temperature). This is enabled by
default
– reentering configured mode

TLE493D-A2B6
Functional Description
In any case functions are only executed if the supply voltage is high enough, otherwise the restart circuit will
halt the state machine until the required level is reached and restart afterwards. The functions are also
restarted if a restart event occurs in between (see parameter ADC restart level).
2.1.2 Sensing
Measures the magnetic field in X, Y and Z direction. Each X-, Y- and Z-Hall probe is connected sequentially to a
multiplexer, which is then connected to an Analog to Digital Converter (ADC). Optional, the temperature
(default = activated) can be determined as well after the three Hall channels.

Functional Description
2.5 Application Circuit
The use of an interrupt line is optional, but highly recommended to ensure proper and efficient readout of the
sensor data.
The pull-up resistor values of the I2C bus have to be calculated in such a way as to fulfill the rise- and fall time
specification of the interface for the given worst case parasitic (capacitive) load of the actual application
setup.
Please note: too small resistive R1/2 values have to be prevented to avoid unnecessary power consumption
during interface transmissions, especially for low-power applications.
Figure 5 Application Circuit with external power supply and µC
For additional EMC precaution in harsh environments, C1 may be implemented by two 100 nF capacitors in
parallel, which should be already given by CBuf near the µC and/or power supply.

3 Specification
This sensor is intended to be used in an automotive environment. This chapter describes the environmental
conditions required by the device (magnetic, thermal and electrical).
3.1 Absolute Maximum Ratings
Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the device at these or any other conditions above those
indicated in the operational sections of this specification is not implied. Furthermore, only single error cases
are assumed. More than one stress/error case may also damage the device.
Exposure to absolute maximum rating conditions for extended periods may affect device reliability. During
absolute maximum rating overload conditions the voltage on VDD pin with respect to ground (GND) must not
exceed the values defined by the absolute maximum ratings.

Specification
3.2 Operating Range
To achieve ultra low power consumption, the chip does not use a conventional, power-consuming restart
procedure. The focus of the restart procedure implemented is to ensure a proper supply for the ADC operation
only. So it inhibits the ADC until the sensor supply is high enough.
The sensor relies on a proper supply ramp defined with tPUP, VOUS and IDD-PUP, see Figure 6. The I2C reset feature
of the sensor shall be used by the µC after Power Up. If supply monitoring is used in the system (e.g. brown-
out detector etc.), it is also recommended to use the I2C reset of the sensor following events detected by this
monitor.
In any case, an external supply switch (either provided by a System-Basis-Chip solution which includes a
supply-enable feature, a Bias-Resistor-Transistor device, a capable µC GPIO pin, etc.) shall allow a power-
cycle of the sensor as backup for high availability applications to cope with any form of VDD ramps (including
potential EMC influences), see Figure 6.
At Power Up, SDA and SCL shall be pulled to VDD using R1 and R2 of Figure 5 and not be driven to low by any
device or µC on SDA and SCL.

3.7 Interface and Timing Description
This chapter refers to how to set the boundary conditions in order to establish a proper interface
communication.
The fast mode, shown in Figure 7, requires a very strict I2C behavior synchronized with the sensor conversions
and high bit rates. In this mode, a fresh measurement cycle is started immediately after the previous cycle was
completed.
Other modes are available for more relaxed timing and also for a synchronous microcontroller operation of
sensor conversions. In these modes, a fresh measurement cycle is only started if it is triggered by an internal
or external trigger source.
In the default measurement configuration (Bx, By, Bz and T), shown in Figure 7, the measurement cycle ends
after the temperature measurement.
In 3-channel measurement configuration (Bx, By and Bz), the temperature channel is not converted and
updated. Thus, the measurement cycle ends after the Bz measurement.

In X/Y angular measurement configuration (Bx and By), the Bz and temperature channel are not converted and
updated. Thus, the measurement cycle ends after the By measurement.
