描述
With the TLE493D-W2B6 A0-A3, a 3D sensor has been developed, which includes an enhanced dynamic wake up feature. Four pre-programmed address options (A0-A3) will be available, enabling for a fast start up initialization, when used in I2 C bus configurations. It also includes enhanced test options and a safety documentation is available to enable the usage of this sensor in the context of ASIL B systems.

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.

Application Circuit with external power supply and µC

For additional EMC precaution in harsh environments, C₁may be implemented by two 100 nF capacitors in

parallel, which should be already given by C_Bufnear the µC and/or power supply.
