MIC5019

The MIC5019 is a high-side MOSFET gate driver with integrated charge pump designed to switch an N-Channel enhancement type MOSFET control signal in high-side or low-side applications.

The MIC5019 operates from a 2.7 V to 9 V supply, and generates gate voltages of 9.2 V from a 3 V supply, and 16 V from a 9 V supply. The device consumes a low 77 µA of supply current and less than 1 µA of supply current in shutdown mode.

In high side configurations, the source voltage of the MOSFET approaches the supply voltage when switched on. To keep the MOSFET turned on, the MIC5019's output drives the MOSFET gate voltage higher than the supply voltage.

The MIC5019 is available in an ultra-small 4-pin 1.2 x 1.2 mm Thin QFN Package and is rated for -40°C to +125°C junction temperature range.
