ZHCSVO2D June 2008 – July 2024 UCC27200-Q1
PRODUCTION DATA
The boot diode necessary to generate the high-side bias is included in the UCC27200-Q1 family of drivers. The diode anode connects to VDD and the cathode connects to VHB. With the VHB capacitor connected to HB and the HS pins, the VHB capacitor charge refreshes every switching cycle when HS transitions to ground. The boot diode provides fast recovery times, low diode resistance, and a voltage rating margin that allow for efficient and reliable operation.
