1 Application Circuits
The application circuits in this chapter show the various communication possibilities of the TLE5014.
Figure 1 shows a basic application circuit of a TLE5014 with PWM interface. The pull-down resistor is required
to ensure that the sensor starts with a low level after power-on or reset (PWM starts with a rising edge). If the
sensor is configured in such a way, that the PWM starts with a falling edge, the pull-down has to be replaced
by a pull-up.

PWM
Figure 2 shows a basic application circuit of the TLE5014 with SPC mode.

Figure 2 Application circuit for TLE5014 with SPC, SPC address is configured to be "0" (IF1 and IF2
connected to GND)
The circuit shows the minimum external circuit which is needed to operate the SPC interface. The generation
of the trigger pulse (switch to pull the line low) is not shown. Depending on EMC requirements, additional
circuitry may be required. The value of C
The TLE5014 can also be used with a SENT interface
