Hi,
I have designed a circuit for driving the three phase BLDC motor using IR 2110.
I got the Ir2110 circuit form a website which is attached below.
Also I designed the circuit in PCB board.
For checking the PCB board working, interface the normal 12v dc motor with the circuit. ..I don't know that this is the proper way for checking the circuit.
but i couldn't able to drive the motor.
And I generated a PWM pulse from the LPC 1343 microcontroller.
Inputs given to the ic
Vdd-5v/12v
Vcc-Vdd
Vss-Gnd
SD-GND
Hin-PWM
Lin-Gnd
Com-Gnd
But i checked the output voltage in HO which is very low.0.3v something i got.
In LO i got zero volt.
I also checked the Vs pin got 9v.
My question is How much voltage will i get in HO.when i give 3.3v in Hin pin?
What is the use of vs pin and vb pin?
Which is important to drive the mosfet gate and how much voltage should i need?
