Charge Pump Gate Driver. General description the mic5019 is a high side mosfet driver with integrated charge pump designed to switch an n channel enhancement type mosfet control signal in high side or low side applications. 8vboost charge pump boost capacitor.
Also limits vgs to 15v maximum to prevent gate to source damage. Its 3 high side and 3 low side output stages are powerful enough to drive mosfets with a gate charge of 400 nc with rise and fall times of approximately 150 ns. An internal charge pump boosts the gate drive voltage above the positive rail fully enhancing an n channel mos switch with no external.
Typical applications are cooling fan water pump electrohydraulic and electric power steering.
Drives the gate of an external power mosfet. General description the mic5019 is a high side mosfet driver with integrated charge pump designed to switch an n channel enhancement type mosfet control signal in high side or low side applications. 8vboost charge pump boost capacitor. 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 the high side fet a few volts above the source voltage so as to switch it on.
