IR2113 Basics
The IR2113 is versatile, high-voltage, high-speed drivers designed to control power MOSFETs and IGBTs with precision and efficiency. They offer independent high- and low-side output channels, making them ideal for demanding power applications. Built with proprietary high-voltage IC (HVIC) and latch-immune CMOS technologies, these drivers are exceptionally robust and resistant to electrical noise, allowing for durable and reliable operation.
These drivers support standard CMOS or LSTTL logic inputs, even down to 3.3V, providing compatibility with modern control systems. Their output stage features a high pulse current buffer, designed to minimize driver cross-conduction and avoid shoot-through currents. Matched propagation delays simplify timing and make the IR2113 well-suited for high-frequency switching applications. Additionally, the floating high-side channel enables control of N-channel MOSFETs or IGBTs at high-side voltages up to 500V or 600V, making these drivers ideal for a wide range of high-voltage applications.

IR2113 Package
The IR2113 is packaged in a 14-DIP, which is well-suited for high-voltage driver circuit designs. The standard pin pitch for the 14-DIP package is 2.54mm, with overall dimensions of approximately 19.6mm in length, 7.62mm in width, and a thickness of about 3.3mm. The pin height and total package height are designed for easy insertion and soldering onto standard circuit boards.
With the 14-DIP packaging, the IR2113 maintains sufficient spacing between pins to reduce the risk of electrical interference and high-voltage breakdown, making it especially suitable for driving high-voltage MOSFETs and IGBTs.
Guide to Use IR2113
First, connect the power supplies. Connect the VCC pin to the low-side power supply, typically ranging from 10 to 20V, and connect the VDD pin to the logic supply, which supports a range of 3.3V to 20V for standard logic levels. Additionally, connect the VB and VS pins to the high-side floating supply and the high-side floating ground, respectively, so the high-side driver can operate correctly. Ensure that all connections are secure to prevent loose connections.
Next, connect the control inputs. LIN and HIN are the logic inputs for the low-side and high-side, respectively, controlling the LO and HO outputs. Use standard CMOS or LSTTL logic levels to provide input signals, ensuring the voltage levels meet the driver’s requirements. By applying a signal to HIN, you can control HO to output a high level, thus driving the high-side switch. Similarly, by applying a signal to LIN, you can control LO to output a high level, driving the low-side switch. The SD pin is the shutdown input, and when a valid signal is applied, it will simultaneously turn off both high and low-side outputs for protection.
Finally, verify and test the circuit. Before powering on the system, double-check that all connections are correct. To prevent high-frequency noise or electromagnetic interference, you can add appropriate decoupling capacitors. Once the power is applied, gradually adjust the input signals and observe the output behavior to ensure stable operation of the circuit.
