Microchip Technology MIC5019 High-Side N-Channel MOSFET Driver

Microchip MIC5019 High-Side N-Channel MOSFET Driver is an ultra-small device with an integrated charge pump that is designed to switch an N-Channel enhancement type MOSFET control signal in high-side or low-side applications. MIC5019 operates from a 2.7V to 9V supply and generates gate voltages of 9.2V from a 3V supply and 16V from a 9V supply. This Microchip device consumes a low 77µA of supply current and less than 1µA of supply current in shutdown mode. In high side configurations, the source voltage of the MOSFET approaches the supply voltage when switched on. The output of the MIC5019 drives the MOSFET gate voltage higher than the supply voltage to keep the MOSFET turned on.
