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 > 22µF in parallel with a ceramic capacitor C = 100nF.
Value for electrolytic capacitor depends on external loads, conducted interferences and
reverse-conducting current IHSX (see Section 4. “Absolute Maximum Ratings” on page
10).
• Recommended value for capacitors at VCC:
Electrolytic capacitor C > 10µF in parallel with a ceramic capacitor C = 100nF.
• To reduce thermal resistance, place cooling areas on the PCB as close as possible to GND
pins and to the die paddle in QFN24.
• Only for the QFN24 versions: The sense pins OUTx SENSE can either be left open or can
be connected to the adjacent OUTx pin. Never use the sense pins OUTx SENSE as power
outputs.
