SLUSCE9B June 2017 – March 2020 UCC27712
The VDD power terminal for the device requires the placement of an energy storage capacitor, because of UCC27712 is 1.8-A, peak-current driver. And requires the placement of low-esr noise-decoupling capacitance as directly as possible from the VDD terminal to the COM terminal, ceramic capacitors with stable dielectric characteristics over temperature are recommended, such as X7R or better.
The recommended storage capacitor is an X7R, 50-V capacitor. The recommended decoupling capacitors are a 1-µF 0805-sized 50-V X7R capacitor, ideally with (but not essential) a second smaller parallel 100-nF 0603-sized 50-V X7R capacitor.
Similarly, a low-esr X7R capacitance is recommended for the HB-HS power terminals which must be placed as close as possible to device pins.
