Application Circuit
Application Notes
It is strongly recommended to connect the blocking capacitors at V
CC
and V
S
as close as
possible to the power supply and GND pins.
Recommended value for capacitors at V
S
:
Electrolytic capacitor C > 22 μF in parallel with a ceramic capacitor C = 100 nF. Value
for electrolytic capacitor depends on external loads, conducted interferences and
reverse conducting current I
Out1,2,3
(see “Absolute Maximum Ratings” on page 7).
Recommended value for capacitors at V
CC
:
Electrolytic capacitor C > 10 μF in parallel with a ceramic capacitor C = 100 nF.
To reduce thermal 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 func-
tion of the T6818/T6828. 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 (
S
tatus
R
egister
R
eset) is set, to ensure a reset of the overtemperature function.
