Applications Information
Power-Supply Decoupling
To achieve the best results when using the device,
decouple the V_DD power supply with a 0.1µF capacitor.
Use a high-quality, ceramic, surface-mount capacitor
if possible. Surface-mount components minimize lead
inductance, which improves performance, and ceram-
ic capacitors tend to have adequate high-frequency
response for decoupling applications.
Decouple the REG25 and REG18 regulator outputs using
1µF and 10nF capacitors (one each per output).
Open-Drain Pins
SCL, SDA, FAULTn, and PGn (when set in MFR_MODE)
are open-drain pins and require external pullup resistors
connected to V_DD to realize high-logic levels.
