When LIN = 1 and Q2 is on, C1 and C2 get charged to the level on VB, which is one diode drop below +VCC. When low, the level on HO is equal to VS, with respect to VS, effectively zero.Д1, C1 and C2 along with the IR2110 form the bootstrap circuitry. When high, the level on HO is equal to the level on VB, with respect to VS. VS is the high side floating supply return. We will soon see how a bootstrap circuitry (diode + capacitor) вЂ“ utilizing VCC, VB and VS вЂ“ is used to provide the floating supply to drive the MOSFET. The output to HO вЂ“ high or low вЂ“ is not with respect to ground, but with respect to VS. A high signal to HIN means that you want to drive the high-side MOSFET, meaning a high output is provided on HO.ДЄ low signal to HIN means that you want to turn off the high-side MOSFET, meaning a low output is provided on HO. When youвЂ™re using SG3525 or TL494 or other PWM controller, you are probably going to have them powered off greater than 10V, meaning the outputs will be higher than 8V when high. When youвЂ™re using microcontrollers the output voltage will be higher than 4V (when the microcontroller has VDD = +5V, which is quite common). This means that it can be used for almost all circuits, since most circuits tend to have around 5V outputs. Thus when VDD = +5V, the IR2110 can be used to drive loads when input вЂњ1вЂќ is higher than 3 point something volts. When VDD = +5V, the logic 1 input threshold is slightly higher than 3V. And in this article/tutorial, I will talk about the IR2110.

Undoubtedly, the most popular such driver chip is the IR2110.

The most common way of driving MOSFETs in such cases is to use high-low side MOSFET drivers. In such situations, there is a need to use high-side drive circuitry alongside low-side drive circuitry. In full-bridge circuits we have 2 high-side MOSFETs and 2 low-side MOSFETs. In half-bridge circuits, we have 1 high-side MOSFET and 1 low-side MOSFET. Many a times we need to use MOSFETs configured as high-side and low-side switches. In many situations, we need to use MOSFETs configured as high-side switches.
