TLP250 Mosfet Driver Dip-8

Pin configuration isolated mosfet driver TLP250

• Pin number one and four are not connected to any point physically. Therefore they are not in use.
• Pin number 8 is used to provide power supply to TLP250 and pin number 5 is a ground pin which provides a return path to the power supply ground. Maximum power supply voltage between 15-30 volt dc can be given to TLP250. But it also depends on the temperature of the environment in which you are using TLP250.
• Pin numbers 2 and 3 are the anode and cathode points of input stage LED. It works like a normal light emitting diode. It has similar characteristics of forward voltage and input current. Maximum input current is in the range of 7-10mA and forward voltage drop is about 0.8 volt. TLP250 provides output from low to high with a minimum threshold current of 1.2mA and above.
• Pin number six and seven is internally connected to each other. Output can be taken from either pin numbers 6 and 7. A totem pole configuration of two transistors is used in TLP250. In case of high input , output becomes high with output voltage equal to the supply voltage and in case of low input, the output becomes low with output voltage level equal to ground.
• Mosfet driver TLP250 can be used up to 25khz frequency due to slow propagation delay.
