... Functional Description 3.1 VCC Pre-Charging and Typical VCC Voltage During Start-up In ICE2QR4765G, a startup cell is integrated into the ® CoolMOS . As shown in Figure 2, the start cell consists of a high voltage device and a controller, whereby the high voltage device is controlled by the controller. The startup cell provides a pre-charging of the VCC capacitor till VCC voltage reaches the VCC turned-on threshold V IC begins to operate ...
