V 1.0, 2010-11

Figure 7

Application circuit for TLE5012 with HS Mode (using internal CLK)

Figure 7

shows a basic block-diagram of the TLE5012 in the Hall Switch Mode. This interface is selectable by

connecting CLK to GND and CSQ to VDD. In addition to the HSM, the SSC Interface can be used by pulling CSQ

to GND. Within the SSC Interface, the HSM is selectable between push-pull and open drain.

Figure 8

Application circuit for TLE5012 with SSC Interface and IIF (using external CLK)

Figure 8

shows a basic block diagram of an angle sensor system using a TLE5012 and a microcontroller for rotor-

positioning applications. The interface configuration depicted is needed for high-speed applications such as

electrical commutated motor drives. It is possible to connect the TLE5012 to a microcontroller via the Incremental

Interface, and for safety reasons also via the SSC Interface.
