5.1.1
The TLE8108EM is supplied by a single power supply line
together. After power supply start-up, the input registers of the device are programmed to OFF mode for all
channels. The output registers must be reset to their default values by programming the Clear mode for all
channels once.
Capacitors at the supply pins
There is a reset pin available. Low level at this pin causes all registers to be set to their default values and the
quiescent supply currents are minimized. This is also true for the Standby Mode in case all channels are
programmed to Clear.
