ATA6837 [Preliminary]
10.1 Application Notes
• 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
HSX
(see Section 4. “Absolute Maximum Ratings” on page 8 ).
• Recommended value for capacitors at VCC:
Electrolytic capacitor C > 10 µF in parallel with a ceramic capacitor C = 100 nF.
• To reduce thermal resistance, place cooling areas on the PCB as close as possible to GND
pins and to the die paddle in QFN24.
