Description Reset and Enable Inputs
The TLE8110EE contains one Reset- and one Enable Input Pin as can be seen in Figure 6.
Description:
Reset Pin [RST] is the main reset and acts as the internal under voltage reset monitoring of the digital supply
voltage V_CC: As soon as RST is pulled low, the whole device including the control registers is reset.
The Enable Pin [EN] resets only the Output channels and the control circuits. The content of the all registers is
kept. This functions offers the possibility of a “soft” reset turning off only the Output lines but keeping alive the SPI
communication and the contents of the control registers. This allows the read out of the diagnosis and setting up
the device during or directly after Reset.
