Infineon Technologies IRS2301SPBF

Overview

IRS2301SPBF from Infineon Technologies (formerly International Rectifier) is a high-voltage, high-speed dual-channel gate driver IC for N-channel MOSFETs and IGBTs in half-bridge configurations. It features independent high-side (floating up to +600V) and low-side output channels, 220ns/200ns typical propagation delays, 120mA/250mA peak output drive current, and 3.3V/5V/15V logic-compatible inputs - used in appliance motor inverters and micro-inverter power stages.

For engineers reviewing the IRS2301SPBF datasheet, IRS2301SPBF pinout, IRS2301SPBF application, or IRS2301SPBF equivalent, key selection criteria include bootstrap-compatible floating channel operation, matched propagation delay (<50ns), dual undervoltage lockout (VCC & VBS), dV/dt immunity up to 50 V/ns, and SOIC-8 package compatibility with industrial motor control PCB layouts.

Technical Context

The IRS2301SPBF integrates a high-voltage level-shifting circuit for the high-side channel and a grounded low-side driver in a monolithic HVIC process. Its floating channel operates with VB referenced to VS, enabling gate drive of high-side switches in buck, half-bridge, and three-phase inverter topologies where VS swings from –5V to +600V.

Logic inputs (HIN/LIN) accept CMOS/LSTTL levels down to 3.3V and directly control HO/LO outputs with in-phase response. Propagation delays are tightly matched (≤50ns max difference), and both channels feature independent UVLO thresholds (4.1V rising, 3.8V falling) with 0.3V hysteresis to prevent erratic switching during supply transients.

Key Specifications

Pinout & Package

IRS2301SPBF is housed in an 8-lead SOIC package (body width 3.9mm, JEDEC MS-012), surface-mount compatible with standard reflow profiles and rated MSL2 per J-STD-020.

FAQ

What is the maximum allowable dV/dt at the VS pin?

The IRS2301SPBF is rated for dV/dt immunity up to 50 V/ns at the VS pin, verified per manufacturer test conditions. This specification ensures reliable operation during fast switching transitions in half-bridge configurations without false triggering of the high-side driver, even when parasitic inductance causes rapid voltage transients on the switching node.

Can IRS2301SPBF drive SiC MOSFETs?

Yes - IRS2301SPBF can drive low-to-mid Qg SiC MOSFETs (e.g., ≤25nC) when operated within its 5–20V VCC/VBS range and with appropriate gate resistor selection. Its 120mA source / 250mA sink capability, fast 200–220ns propagation, and 50 V/ns dV/dt immunity make it suitable for 650V-class SiC half-bridge stages up to ~100kHz switching frequency.

Is an external bootstrap diode required?

Yes - an external fast-recovery bootstrap diode (e.g., 1N4148WS or equivalent) is mandatory between VCC and VBS to charge the bootstrap capacitor during LO conduction. The diode must support ≥20V reverse voltage and ≤30ns reverse recovery time to maintain VBS stability during high-frequency operation and prevent high-side driver dropout.

Does IRS2301SPBF include internal pull-down resistors on HIN/LIN?

No - IRS2301SPBF does not integrate internal pull-down resistors on HIN or LIN inputs. External 10–100kΩ pull-down resistors are required on both inputs to ensure defined logic states during power-up, reset, or open-circuit conditions, preventing unintended high-side or low-side turn-on that could cause shoot-through in the power stage.
