Applications
IR2301STR is used in half-bridge and synchronous buck converter designs for motor drives, industrial power supplies, and battery chargers. The device drives MOSFETs and IGBTs in DC-DC converters operating up to 600 V bus voltages. It is also suitable for LED driver stages and Class D audio amplifiers where high-frequency switching up to hundreds of kilohertz is required.

Frequently Asked Questions
What is the maximum bootstrap supply voltage that IR2301STR can handle on its high-side floating rail?
The IR2301STR supports a high-side floating supply offset voltage up to 600 V, making it suitable for 400 V AC mains half-bridge topologies. The gate drive voltage range is 10 V to 20 V, and the device can source 200 mA and sink 420 mA into a gate load.
Which half-bridge motor drive designs benefit most from the IR2301STR's shoot-through protection?
Brushless DC motor controllers and permanent magnet synchronous motor drives benefit most, since simultaneous high-side and low-side conduction would destroy both switches. The IR2301STR enforces an internal deadtime, reducing losses and component stress when switching at frequencies up to 100 kHz with a 3.3 V logic input.
How does IR2301STR's 8-SOIC footprint compare to through-hole gate driver alternatives for compact PCB designs?
The 8-SOIC package occupies roughly 30 mm² board area versus over 100 mm² for a DIP-8 through-hole equivalent, allowing denser layouts. Pin 1 to 8 span only 4.9 mm, enabling short gate drive traces that reduce parasitic inductance and ringing at 20 V gate voltage swing.
Can IR2301STR drive IGBTs in a 600 V industrial inverter, and what gate resistor value is recommended?
Yes, IR2301STR can drive IGBTs rated up to 600 V. A gate resistor of 10 ohm to 33 ohm is typically used to limit dV/dt and ringing while still achieving sub-100 ns turn-on with the device's 420 mA sink current capability at 15 V gate bias.
