Locate UCC27712 as close as possible to the MOSFETs in order to minimize the length of high-current traces between the HO/LO and the Gate of MOSFETs, as well as the return current path to the driver HS and COM.
A resistor in series with bias supply and VDD pin is recommended.
Locate the VDD capacitor (CVDD) and VHB capacitor (CBOOT) as close as possible to the pins of UCC27712.
A 2-Ω to 20-Ω resistor series with bootstrap diode is recommended to limit bootstrap current.
A RC filter with 10 Ω to 100 Ω and 10 pF to 220 pF for HI/LI is recommended.
Separate power traces and signal traces, such as output and input signals.
Maintain as much separation as possible from the from the low voltage pins and floating drive HB, HO and HS pins.
Ensure there is not high switching current flowing in the control ground (input signal reference) from the power train ground.
If 2-kV HBM ESD rating is needed on IC pins, it is acceptable to place a 100-pF capacitor from each pin to ground in order to pass up to 2kV HBM ESD.
