In the daatasheet circuit diagram of IR, the low side and high side blocks are separated with a dotted line for simplicity. So, high output is obtained at LO pin. 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.

Choosing Motor For Robots. Check the input voltage limits from the datasheet of IR The respective voltage outputs then can be drawn from the pin 3 of the regulator ICs. This high-density System-in-Package SiP integrates controller, power switches, and support components.

SPI Module of Arduino. Testing the IR IC. While assembling the circuit for testing the IR IC, following precautions must be taken care of.

Testing IR Gate Driver IC | EngineersGarage

After applying the square waves at Lin and Hin pins, the following voltage waveforms at the Lo and Ho pins were observed ddatasheet a Cathode Ray Oscilloscope. How the circuit works. Interface Xatasheet Card with Arduino. If the IC is heating too fast despite not exceeding input supply voltages beyond limit, then also the IC ri2110s be predicted to be faulty. Exclusive Digi-key Tools Embedded computers. Log in or register to post comments reads.


It has the following pin configuration. In this tutorial, the method to test the IR IC is discussed. This should be done to avoid any undermine state at the output. In the previous tutorial, it was discussed that for driving a MOSFET as high side switch, a gate driver circuit needs to be used.

It can now be used as a gate driver circuit for Half bridge or full H-bridge circuit without doubt.

Internal block diagram of IR The IC is having independent low and high side output channel. The IR has the following pin diagram. The generated square wave from the controller should be applied at the Hin and Lin pins and at the output pins LO and HO respectively a square wave datasehet same amplitude and frequency should be obtained.

The IR has the following internal circuitry. Make proper connections as loose connections can result into abrupt wave at the output. The square wave which has to be applied at the input datashwet Lin and Hin pin is generated by a microcontroller. This pin is active high, so for enabling the IC to work, this pin is connected to the ground.

Arduino based GPS receiver. So, the IR IC under test is working properly. For voltage regulation, the anode of the battery should be connected to pin 1 of the voltage regulator ICs and pin 2 should be grounded. The controller works on TTL transistor- transistor logic. 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.

Always common the ground of 12V and 5V supply. 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.


Virgin Galactic — Commercial Space Flight. Apply a clean DC to the IC to avoid any voltage spikes. 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. For this, an electrolyte capacitor in parallel with ceramic capacitor for filtering the input power supply can be used. 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 square wave can be generated using any microcontroller board.

What is Web Browser. A square wave is applied at the Lin and Hin pin with the zero phase difference between them and the wave is generated using a microcontroller. DC power supply of 5V and 12V. This gives high output at HO pin. If the exact square wave is not obtained at the LO and HO pins or no square wave is output fromeither pin, then Datasehet in case is faulty.

Skip to main content. In testing for this IC, the square wave has been generated using Arduino board.

Interface GPS with Arduino. Choosing Battery for Robots. The Arduino is the most popular prototyping board and can be easily programmed to generate a perfect square wave. In the next tutorial learn about improving the switching time of relays.
