IR2110S Datasheet PDF

Choosing Motor For Robots. Apply a clean DC to the IC to avoid any voltage spikes. 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.

Exclusive Digi-key Tools Embedded computers. For voltage lr2110s, the anode of the battery should be connected to pin 1 of the voltage regulator ICs and pin 2 should be grounded. Check the input voltage limits from the datasheet of IR So, high output is obtained at LO pin. This high-density System-in-Package SiP integrates controller, power switches, and kr2110s components.

SPI Module of Arduino. Interface SD Card with Arduino. In the previous tutorial, it was discussed that for driving a MOSFET as high side switch, a gate driver circuit needs to be used.

What is Web Browser.

In testing for this IC, the square wave has been generated using Arduino board. DC power supply of 5V and 12V. After applying the square waves at Lin and Hin pins, the following voltage waveforms at the Lo and Ho pins were observed on a Cathode Datashete Oscilloscope.


Make proper connections as loose connections can result into abrupt wave at the output. Choosing Battery for Robots.

Testing the IR IC. So, the IR IC under test is working properly. The square wave which has to be applied at the input of Lin and Hin pin is generated by a microcontroller.

The IC is having independent low and high side output channel. 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. Arduino based GPS receiver. Before using this IC for driving the half or full bridge circuit, it is necessary to test the faultiness of the IC. The Arduino is the most popular prototyping board and can be easily programmed to generate a perfect square wave.

Interface GPS with Arduino. This pin is active high, so for enabling the IC to work, this pin is connected to the ground.

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.

Testing IR2110 Gate Driver IC- ( Part 14/17)

How the circuit works. 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 of same amplitude and frequency should be obtained. This should be done to avoid any undermine state at the output.

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

The IR has the following internal circuitry. Virgin Galactic — Commercial Space Flight. By using a single IC, a half bridge circuit can be operated in which one MOSFET is in high side configuration dstasheet another one is in the low side configuration.


It can now be used as a gate driver circuit for Half bridge or full H-bridge circuit without doubt. In the internal circuit diagram of IR, the low side and high side blocks are separated with a dotted line for simplicity.

For this, an electrolyte capacitor in parallel with ceramic capacitor for filtering the input power supply can be used. The square wave can be generated using any microcontroller board. 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. From the adtasheet waveforms observed on CRO, it can be seen that it has the same amplitude and frequency as of the input square wave.

The respective voltage outputs then can be drawn from the pin 3 of the regulator ICs. Always common the ground of 12V and 5V supply. The IR has the following pin diagram. Skip to main content. In this tutorial, the method to test the IR IC is discussed. This gives high output at HO pin. Internal block diagram of IR Log in or register to post comments reads.

The VDD is the supply voltage for driving the internal circuitry of the IC and it should be in between 3V to 20 Datzsheet with reference to Vss as per the datasheet. It has the following pin configuration .
