What is TLP250?
TLP250 is suitable for the gate driving circuit of IGBT or power MOS FET. A GaAlAs light-emitting diode is used on the input side. An integrated photodetector provides a driving signal to the output side. As a result, electrical isolation between low and high power circuits is the most important aspect. It uses light to transmit electrical impulses.
It may be used to drive the gate terminal of high voltage switches in both high and low side drive configurations. It's packaged as an 8-pin DIP chip.

Isolated MOSFET Driver Working
There are two stages in the TLP250: an input stage and an output stage. A power supply setup is also included. It is better for MOSFETs and IGBTs. This MOSFET driver is optically isolated, which sets it apart from other MOSFET drivers. Its electrical input and output sides are electrically insulated from one another. However, an optical signal is used to transport electrical signals between the two sides. It functions similarly to an optocoupler. A light-emitting diode is used in the input stage, while a photodiode is used in the output stage, The output gets high whenever the input stage LED light falls on the output stage photodetector diode.
TLP250 IGBT Driver as A Low Side Gate Driver
The low-side Mosfet driver circuit employing the TLP250 is illustrated below. The TLP250 is utilized as a non-inverting low-side Mosfet driver in this circuit layout. Between the power source and the electrolytic capacitor, a 0.47 uf electrolytic capacitor should be connected. It protects the TLP250 by giving a constant voltage to the IC.
Isolated MOSFET driver TLP250 as a Low Side Driver
Input is a driving signal that drives the output, as indicated in the diagram above. Signal ground is used to calculate Vin. It should be kept away from the supply and output grounds. The load ground is referenced to the power ground and is separated from the input signal reference ground, as indicated in the above figure TLP250. MOSFET Q1 receives a high signal from TLP250 when input is high, and it is powered by a power source, allowing current to flow through the load.
MOSFET Q1 receives a low signal from a TLP250 output pin when input is low, and Mosfet Q1 remains off and no current flows to the load. The supply voltage is typically between 10 -15 volts. Depending on the magnitude of the input signal, the input resistor at the gate of the MOSFET is employed. Typically, the input signal is given by a microcontroller, with a level of 5 volts for the microcontroller input signal. As a decoupling capacitor, capacitor C1 is employed.
TLP250 IGBT Driver as A a High Side MOSFET/IGBT Driver
The following is a circuit schematic for the TLP250 MOSFET /IGBT driver, which is utilized as a high side driver, It's a high-side gate drive circuit that isn't inverting. Because the input signal ground is linked to the input stage light-emitting diode's cathode. As a result, it's referred to as a non-inverting high-side gate driver.
TLP250 as a High Side MOSFET IGBT Driver
As illustrated in the diagram above, there are three grounds in a high side layout. The input signal's ground, the supply voltage's ground, and the power supply voltage's ground. When utilizing the TLP250 as a high-side MOSFET driver. keep in mind that all grounds should be separated from one another.
