PRODUCTION DATA
Connect a 2.2-μF, 6.3-V (or 10 V) rated ceramic capacitor to AGND for bypassing of the VCC pin.
Connect a 2.2-μF, 6.3-V (or 10 V) rated ceramic capacitor to PGND for bypassing of the VDRV pin. This bypass capacitor must refer to PGND pin 7 - 10 to minimize the length of high-frequency driving current path.
Placing a 1-? resistor between the VCC and VDRV pin forms a RC filter on VCC pin, which greatly reduces the noise impact from power stage driver circuit.
