Testing IR2110 Gate Driver IC- ( Part 14/17)
What is Web Browser. The respective voltage outputs then can be drawn from the pin 3 of the regulator ICs. This pin is active high, so for enabling the IC to work, this pin is connected to the ground. Interface GPS with Arduino. Before using this IC for driving the half or full bridge circuit, it is necessary to test the faultiness of the IC. From the internal circuit it can be seen that in high side and lows side, there are two MOSFETs at the end followed by a latch on high side and an AND gate on low side.
The IR has the following internal circuitry. Since the square wave has to be applied at two pins of the IR, the Arduino is programmed to output square wave from two of its pins. The IR has the following pin diagram.
Arduino based GPS receiver. If the exact square wave is not obtained at the LO and HO pins or no square wave is output fromeither pin, then IR in case is faulty. Check the input voltage limits from the datasheet of IR The square wave can be generated using any microcontroller board. The square wave which has to be applied at the input of Lin and Hin pin is generated by a microcontroller.
Choosing Battery for Robots. How the circuit works. It has the following pin configuration. In the previous tutorial, it was discussed that for driving a MOSFET as high side switch, a gate driver circuit needs to be used.
Virgin Galactic — Commercial Space Flight. Make proper connections as loose connections can result into datasbeet wave at the output. From the voltage waveforms observed on CRO, it can be seen that it has the same amplitude and frequency as of the input square wave. Internal block diagram of IR So, the IR IC under test is working properly. If the IC is heating too fast despite not exceeding input supply voltages beyond limit, then also the IC can be predicted to be faulty.
In the internal circuit diagram of IR, the low side and high side blocks are separated with a dotted line for simplicity.
Datsaheet Arduino is the most popular prototyping board and can be easily programmed to generate a perfect square wave. This should be done to avoid any undermine state at the output. Interface SD Card with Arduino. In testing for this IC, the square wave has been generated using Arduino board. Choosing Motor For Robots.
The generated square wave from the controller should be applied at the Hin and Lin pins ratasheet at the output pins LO and HO respectively a square wave of same amplitude and frequency should be obtained. This gives high output at HO pin.
A square wave is applied at the Lin and Hin pin with the zero phase difference datasueet them and the wave is generated using a microcontroller. Testing the IR IC.

So, high output is obtained at LO pin. In the next tutorial learn about improving the switching time of relays. Exclusive Digi-key Tools Embedded computers. The VDD is the supply voltage for driving the internal circuitry of the IC and it should be in between 3V to 20 V with reference to Vss as per the datasheet.

After applying the square waves at Lin and Hin pins, the following voltage waveforms at the Lo ir21110s Ho pins were observed on a Cathode Ray Oscilloscope. Skip to main content.
For voltage regulation, the anode of the battery should be connected to pin 1 of lr2110s voltage regulator ICs and pin 2 should be grounded. Apply a clean DC to the IC to avoid any voltage spikes. The IC is having independent low and high side output channel. For this, an electrolyte capacitor in parallel with ceramic capacitor for filtering the input power supply can be used.
The controller works on TTL transistor- transistor logic. In this tutorial, the method to test the IR IC is discussed. It can now be used as a gate driver circuit for Half bridge or full H-bridge circuit without doubt. This high-density System-in-Package SiP integrates controller, power switches, and support components. By using a single IC, a half bridge circuit can be operated in which one MOSFET is in high side configuration and another one is in the low side configuration.

Log in or register to post comments reads. While assembling the circuit for testing the IR IC, following precautions must be taken care of. SPI Module of Arduino. DC power supply of 5V and 12V.
