What Is the IR2110? High/Low-Side Gate Driver and Uses

November 1, 2026 6 min read
Quick answer

The IR2110 is a high-side & low-side MOSFET/IGBT gate driver. In half/full bridges and inverters it drives the top (floating-referenced) and bottom power switches via HIN/LIN inputs; the top side uses a bootstrap (diode+capacitor). WATCH OUT: it does not generate dead-time internally — you must provide dead-time to prevent shoot-through (for internal dead-time use the IR2104).

The IR2110 is a high-side & low-side MOSFET/IGBT gate driver. It is used to drive the top (floating-referenced) and bottom power switches in a half/full bridge or inverter quickly and correctly. For the concept, see what is a gate driver.

What is the IR2110 used for?

Motor drives, inverters, SMPS and H-bridge/half-bridge topologies. With HIN and LIN inputs it drives the top and bottom MOSFET independently; the top side uses a bootstrap circuit (diode + capacitor). It supplies the high gate current a logic pin cannot.

Key pins (functional — PDIP-14)

Since numbers can vary by version, they are given by function; for exact numbers see the datasheet.

  • HIN / LIN: top / bottom channel logic inputs.
  • SD: shutdown.
  • VDD / VSS: logic supply / logic ground.
  • VCC / COM: low-side gate-drive supply / power reference.
  • VB / VS: high-side floating supply (bootstrap) / high-side reference.
  • HO / LO: top / bottom gate outputs.

Watch out: bootstrap and dead-time

To drive the top MOSFET, a bootstrap capacitor between VB-VS and a (fast) bootstrap diode from VCC to VB are needed. To prevent the top and bottom switch conducting at once (shoot-through), dead-time must be provided in software/hardware (the IR2110 does not generate dead-time internally).

Equivalents

  • IR2104: a half-bridge driver with internal dead-time.
  • IR2113: a close, higher-voltage version.
  • TLP250: an isolated gate driver (optocoupler).

Frequently Asked Questions

What is the IR2110?+
The IR2110 is a high-side and low-side MOSFET/IGBT gate driver. In half/full bridges and inverters it drives the top (floating-referenced) and bottom power switches via the HIN/LIN inputs; the high side uses a bootstrap.
What is IR2110 bootstrap?+
To drive the high-side MOSFET you need a bootstrap capacitor between VB-VS and a fast bootstrap diode from VCC to VB; this generates the floating high-side supply.
Does the IR2110 generate dead-time?+
No; the IR2110 does not generate dead-time internally. To prevent shoot-through you must provide dead-time in software/hardware. For a driver with internal dead-time use the IR2104.
What is an equivalent to the IR2110?+
The IR2104 for internal dead-time; the higher-voltage IR2113; the TLP250 (optocoupler) for an isolated gate driver.
