High Side Fet Driver For Mac
While designing the UPS circuits, MOSFET were used in the inverter circuits. The MOSFET were used as High side switches in the circuit.
For driving the MOSFET in high side configuration, IR2110 gate driver IC was used. IR2110 is a High –Low side Gate Driver IC which is used with power MOSFET and IGBT. A Gate Driver is a specially designed circuit that is used to drive the Gate of MOSFET or IGBT in High Side Switching application. That means when MOSFET/IGBT is used in High side configuration then a Gatedriver IC is need to be used.
While assembling these circuits, always use a gate to source resistance (Shown as Rgs in the circuit diagram) to avoid any external noise at the gate. This resistance also discharge the parasitic capacitance of the MOSFET. Otherwise, the MOSFET can get damaged as this parasitic capacitor will keep on charging and exceed the limit of the gate to source breakdown voltage. Also, do not exceed the input voltage (drain voltage and gate voltage) of MOSFET greater than its breakdown voltage as it can damage the MOSFET. A low-value resistor (10E to 500E) should be used at the gate of MOSFET. This will solve the problem of ringing (parasitic oscillations) and voltage spike in the MOSFET.

Some manufacturers also provide specially designed ICs (commonly known as gate driver ICs) for driving the high side MOSFET. Depending on the type of IC, the IC can drive only high side or low side or it can drive high as well as low side switching simultaneously. So ICs which can drive both high and low side switching can drive the half bridge circuit, which uses one MOSFET in high side and another one in low side configuration. So for driving an H-bridge circuit (combination of two half bridge), two gate drive ICs each for driving single half-bridge need to be used. Generally, these ICs work on bootstrap technique for driving the high side MOSFET and for low side MOSFET, these simply use a transistor logic.
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. The 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. The device consumes a low 77µA. High Side Low Side Mosfet Driver.
