UM11216 NXP Semiconductors PCA9420UK-EVM evaluation board user manual 14 Layout Guideline The following guidelines for PCA9420UK are arranged from most critical to least critical priority: • Place ASYS input capacitor (C2) as close to ASYS and PGND as possible. • Place VBAT input capacitor (C3) as close to VBAT and PGND as possible. The input capacitor delivers a high di/dt current pulse when the high-side MOSFET turns on.
