High side mosfet driver charge pump
WebA higher voltage, used to erase cells, is generated internally by an on-chip charge pump. Charge pumps are used in H bridges in high-side drivers for gate-driving high-side n-channel power MOSFETs and IGBTs. When the centre of a half bridge goes low, the capacitor is charged through a diode, and this charge is used to later drive the gate of ... WebMay 1, 2024 · A charge pump circuit, or charge pump regulator, is a kind of DC-DC converter that leverages switched-capacitor techniques to either increase or decrease an input voltage level. As shown in Figure 1, these …
