Part Number: MIC5019YFT-EV
MIC5019YFT EVALUATION BOARD
- Refer to User Guide.
Overview
The MIC5019 is a high-side MOSFET driver with integrated charge pump designed to switch an Nchannel enhancement type MOSFET in high-side or low–side applications.
The MIC5019 operates from a 2.7V to 9V supply. It generates gate voltages of 9.2V from a 3V supply and 16V from a 9V supply. The 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. To keep the MOSFET on, the MIC5019’s output drives the MOSFET gate voltage higher than the supply voltage.
N/A
The MIC5019 evaluation board needs only a single power supply to power the driver and a function generator or logic signal to drive the IN pin. If the application needs different supplies for driver and load, then another supply may be used to power the external MOSFET at the VEXT (J7 and J6) by loading the resistor R1 and cutting the traces indicated by R4.
