Protection from EMI
Transients generated by electromagnetic interference (EMI)
can disturb operation of the A6850 or add unwanted noise to the
signals being processed.
The scheme shown in figure 9 illustrates possible supply decou-
pling and signal filtering options. The selection of protection and
filtering component values will depend on the details of the final
application.
The A6850 must be protected with a suitable bypass capacitor to
prevent transients entering VIN. The capacitor should be as close
to the VIN and GND pins as feasible.
A pi-filter placed between the OUTPUTx pins and the sensor IC
has been shown to demonstrate excellent performance in nor-
mal automotive Bulk Cable Injection (BCI) testing. However,
component selection and layout as well as cable specification and
placement must be tailored to the individual application. EMC
results should be validated.
