IR2113

IR2113S

If you’re designing a half-bridge or full-bridge circuit, IR2113S is an ideal driver. It drives both high-side and low-side N-channel MOSFETs at up to 600V on the high side, perfect for high-voltage applications. It offers ±2A peak output current for powerful MOSFETs, built-in dead-time to avoid shoot-through, and UVLO protection on both sides for stability. The inputs support 3.3V and 5V logic signals, and the compact SOP package helps simplify PCB layout.

IR2113S Pinout

When you’re wiring up the IR2113S, add a bootstrap capacitor (0.1~1μF) between VB and VS to power the high-side MOSFET properly. HIN/LIN inputs are logic-level compatible (TTL/CMOS)—never connect them directly to high voltage. The SD pin can shut off both MOSFETs if pulled low, perfect for protection. COM and VSS should share the same ground reference. Also, keep enough dead-time to prevent shoot-through. For higher voltages (300V or more), maintain proper spacing around VB/VS lines to avoid insulation issues or arcing.

IR2113S Equivalent

If you’re currently using the IR2113S and looking for an alternative, the IR2110S is your closest match—similar specs and package, just slightly different pin functions, so check the datasheet carefully. IRS2186S and IRS21094S come in smaller SOIC-8 packages with simpler features, better for compact, lower-voltage designs. Avoid these two for high-voltage applications like a 600V full-bridge. Always match your requirements in voltage rating, current capability, and package size before deciding.

IR2113S Half Bridge Driver Circuit

This circuit is a typical IR2113S half-bridge driver, common in motor control or high-voltage inverter applications. Your control signals (HIN/LIN) switch the MOSFETs through IR2113S, which manages dead-time protection internally. The bootstrap capacitor between VB and VS boosts voltage to drive the high-side MOSFET. It supports voltages up to 600V; logic supply is usually around 12V. Be careful with high-voltage spacing in your layout.

IR2113S MOSFET Driver Application

If you’re looking for a reliable half-bridge driver, IR2113S is a great pick, especially when driving high-voltage N-channel MOSFETs. It’s perfect for motor drives (like BLDC or servo motors), DC-AC inverters (solar, UPS), high-frequency switching power supplies, wireless charging, and induction heating. It’s also useful in variable-frequency drives for industrial fans or AC compressors. Overall, it fits many high-voltage applications.

IR2113S Inverter Control Schematic

Check out this IR2113S inverter schematic—it’s essentially a half-bridge inverter. The IR2113S chip drives two N-channel MOSFETs (high-side and low-side) via HIN and LIN signals from your controller. The SD pin lets you safely disable the outputs. A bootstrap capacitor provides voltage for the high-side MOSFET. PWM signals alternate MOSFET switching, creating an AC output suitable for UPS, solar inverters, or motor drives. It easily handles high voltages around 500-600V DC, making it highly practical for various applications.
