It is strongly recommended to connect the blocking capacitors at V
ble to the power supply and GND pins.
Recommended value for capacitors at V
Electrolytic capacitor C > 22 µF in parallel with a ceramic capacitor C = 100 nF. Value for elec-
trolytic capacitor depends on external loads, conducted interferences and reverse conducting
current I
Recommended value for capacitors at V
Electrolytic capacitor C > 10 µF in parallel with a ceramic capacitor C = 100 nF. To reduce ther-
mal resistance it is recommended to place cooling areas on the PCB as close as possible to the
GND pins. Negative spikes at the output pins (e.g. negative spikes caused by an inductive load
switched off with a high side driver) may activate the overtemperature protection function of the
T6818. In this condition, all outputs will be switched off simultaneously. If this behavior is not
acceptable or compatible with your application functionally, it is necessary, that for switching on
required outputs again, the SRR bit (Status Register Reset) is set, to ensure a reset of the over-
temperature function.
