Ir2110 Mosfet Gate Driver Ic

Their respective roles are discussed in section 2 3 which is dedicated to the switching procedure of the device.

Ir2110 mosfet gate driver ic.

Features floating channel designed for bootstrap operation fully operational to 500v or 600v tolerant to negative transient voltage dv dt immune gate drive supply range from 10 to 20v undervoltage lockout for both channels 3 3v logic compatible separate logic supply range from 3 3v to 20v. 500 v high side and low side gate driver ic with shutdown. Power mosfet models figure 2c is the switching model of the mosfet. The range of separate voltage supply is from 3 3v to 20v and supply range of gate driver is from 10 to 20 v.

By using a single ic a half bridge circuit can be operated in which one mosfet is in high side configuration and another one is in the low side configuration. Eicedriver 2edl is a 600v half bridge gate driver ic family basing on level shifter soi silicon on insulator technology which integrates low ohmic ultrafast bootstrap diode and supports higher efficiency and smaller form factors of applications. By apogeeweb ir2110 2110 ir2110 datasheet ir2110 pinout ir2110 circuit mosfet driver igbt driver. Now in this tutorial bootstrap circuit method to drive a high side mosfet will be discussed.

Rc circuit model for a gate driver with mosfet output stage and power device as a capacitor. The ir2110 is a high voltage high speed power mosfet and igbt driver with independent high and low side referenced output channels. High and low side driver ic with source current 0 25 a and sink current 0 5 a. In h bridge used in pure sine wave inverter design 2 mosfet are used as high side mosfet and 2 mosfet is used as low side mosfet.

The ir2110 ic is one of the high speed and high voltage gate driver ics for igbt and power mosfet. The use of ir2110 gate driver ic has also been discussed in the same tutorial. For a specific drive current the lower value of r ds on allows higher r ext to be used. Ir2210 can withstand voltage up to 500v offset voltage.

The most important parasitic components that influences switching performance are shown in this model. Ir2110 comes in 14 pin through hole pdip package and the 16 pin surface mount soic package. It can tolerate negative transient voltage. It has a floating circuit to handle to bootstrap operation.

Operating supply voltage range for ir2110 is 10 to 20 volt and output current is 2 5a. Fundamentals of mosfet and igbt gate driver circuits figure 2. Ir2112 mosfet igbt driver features. It has a feature of floating channel which can perform bootstrap operation.
