$begingroup$I want to turn on and off both the mosfets at same time and I used IR2110 gate drivers for high and low MOSFETS. https://sugaryellow429.weebly.com/blog/ttl232r-3v3-driver. Allen bradley rslogix 5 download.
When I try to simulate the circuit, after few seconds it shows error saying time step too small. Pm45 express chipset driver for mac. What is the problem with circuit or simulations?
Isolated Mosfet Driver
MT Delay matching, HS & LS (IR2110) — — — 10 turn-on/off (IR2113) — — — 20 ns Dynamic Electrical Characteristics VBIAS (VCC, VBS, VDD) = 15V, CL = 1000 pF, TA = 25°C and VSS = COM unless otherwise specified. The dynamic electrical characteristics are measured using the test circuit shown in Figure 3. The IR2110 is a high voltage, high speed power MOSFET and IGBT driver with independent high and low side referenced output channels. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. Mosfet – Gate driver IR problems – Electrical Engineering Stack Exchange Hi Tahmid, First of all it is ir2110 mosfet really helpful blog for electrnic lovers; I really thank to you. Have you experience the output the drivers getting damaged either the high side or low side and if so what was the probable cause. International rectifiers IR2110 MOSFET driver can be used as high side and low side MOSFET driver. Download brother driver for mac. It have a floating circuit to handle to boostrap operation. International rectifiers IR2110 MOSFET driver can be used as high side and low side MOSFET driver. It have a floating circuit to handle to boostrap operation. IR2210 can with stand voltage upto 500v (offset voltage).

$begingroup$Not sure about the LTSpice error, but I do see one problem. In order for the high side IR2110 to work, the bootstrap capacitance (C1 and C3) must be charged so that 12 volts appears across it. This is done by pulling the VS pin to ground, which happens every time you switch the low side on a normally-configured half bridge. In your circuit, this capacitor will not ever be charged. C1 and C3 must be refreshed periodically by pulling VS to ground; the charge on the cap provides the current and voltage necessary to get the high side gate drive voltage to a voltage greater than your 12 V supply. If the charge on this cap is less than 8 volts or so, the high side switch will shut off. You could put in the low side FET instead of D2 and pulse it at the start and then again periodically.
