3.3 HSM interface and SSC (HSM in open-drain configuration)
As shown in Figure 3-3 when IFA, IFB and IFC are configurated via the SSC interface as open drain pins, three
pull-up resistors (Rpu) should be added on the output lines.

3.4 PWM interface (push-pull configuration)
The TLE5012B can be configured with PWM only (Figure 3-4). The derivate TLE5012B - E5000 is by default
configurated with push-pull configuration for IFA (PWM) pin. Internal pull-up resistors are always available for
DATA and CSQ pins (see Datasheet). It is recommended to connect CSQ pin to V
DD
to provide a high level and
avoid unintentional activation of the SSC interface. DATA pin should be left open. The figure below shows a typical
implementation of the TLE5012B - E5000.
