Webthere is a 2ms delay on the charge pump, but the charge pump is only used to trickle charge the mosfet gate, which should already be boosted by the usual bootstrap mechanism. if the high side fet is on for less than 2ms, it will not need a charge pump (presumably). WebN-channel ones. In this configuration, when the high side switch is realized with a P-channel MOSFET, the driver design will be simplified enormously. No charge pump is required for driving the high side switch; it can easily be driven by the MCU via a level shifter. Figure 3.1: Low-Voltage drive application circuit

WebMay 3, 2007 · The high-side power switch manages the output power and, therefore, typically limits its output current. Conversely, the high-side load switch passes the input voltage and current to the load and, as such, it does not incorporate the current-limiting function. The high-side load switch consists of the following three elements: WebYou can use a charge pump, develop an auxiliary supply to drive the FET gate. Some integrated load switch drivers have a charge pump built in and provide other useful features. There are also integrated high side load switches that can be useful for certain load ranges.
