TLE8110ED

Smart Multichannel Low Side Switch with Parallel Control and SPI Interface

Reset and Enable Inputs

6.1

Description Reset and Enable Inputs

The TLE8110ED contains one Reset- and one Enable Input Pin as can be seen in Figure 5.

Description:

Reset Pin [RST] is the main reset and acts as the internal under voltage reset monitoring of the digital supply

voltage VCC: 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.
