Table 4-1 Absolute maximum ratings

Attention: Stresses above the max. values listed here may cause permanent damage to the device. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Maximum ratings are absolute ratings; exceeding only one of these values may cause irreversible damage to the device.

The application circuits in this chapter show the various communication possibilities of the TLE5012B. The pin output mode configuration is device-specific and it can be either push-pull or open-drain. The bit IFAB_OD (register IFAB, 0D H ) indicates the output mode for the IFA, IFB and IFC pins. The SSC pins are by default pushpull (bit SSC_OD, register MOD_3, 09 H ).

Figure 3-1 shows a basic block diagram of a TLE5012B with Incremental Interface and SSC configuration. The derivate TLE5012B - E1000 is by default configured with push-pull IFA (IIF_A), IFB (IIF_ B) and IFC (IIF_IDX) pins.

Figure 3-1 shows a basic block diagram of a TLE5012B with Incremental Interface and SSC configuration. The derivate TLE5012B - E1000 is by default configured with push-pull IFA (IIF_A), IFB (IIF_ B) and IFC (IIF_IDX) pins.

In case that the IFA, IFB and IFC pins are configurated via the SSC interface as open-drain pins, three resistors (one for each line) between output line and V DD would be recommended (e.g. 2.2k Ω ).
