Infineon Technologies IR2301

Overview

IR2301 from Infineon Technologies (formerly International Rectifier) is a high-voltage, high-speed dual-channel gate driver IC for N-channel MOSFETs and IGBTs, featuring independent high-side (floating up to +600 V) and low-side output channels. It supports 3.3 V/5 V/15 V logic inputs, delivers ±200 mA peak output current, exhibits matched propagation delay (≤50 ns), and operates with VCC from 5–20 V and VB–VS up to 600 V - used in half-bridge motor drives and SMPS.

For engineers reviewing the IR2301 datasheet, IR2301 pinout, IR2301 application, or IR2301 equivalent, key selection criteria include high-side floating capability, dV/dt immunity, undervoltage lockout on both channels, logic-level compatibility down to 3.3 V, and thermal performance in PDIP/SOIC packages under industrial temperature range (−40°C to +150°C).

Technical Context

The IR2301 integrates proprietary HVIC (High-Voltage IC) technology enabling monolithic high-side level shifting without external bootstrap diodes. Its floating channel uses pulse-transformer-based level shift with latch-immune CMOS logic, supporting VS transients up to 50 V/ns and logic operation across −5 V to +600 V offset.

Both channels feature independent undervoltage lockout (UVLO) with hysteresis (0.3 V), matched turn-on/turn-off delays (typ. 220/200 ns), and in-phase input-to-output response. The driver employs lower di/dt gate drive stages and internal pulse filtering to suppress noise-induced false triggering in high-noise power-conversion environments.

Key Specifications

Pinout & Package

IR2301 is available in 8-lead PDIP (IR2301) and 8-lead SOIC (IR2301S) packages, both with 0.3-inch body width and standard lead pitch. Thermal resistance is 125°C/W (PDIP) and 200°C/W (SOIC) under still-air conditions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side/low-side gate driver applications.

Compared with IR2301, IR2101 offers reduced drive strength and looser timing control but lower BOM cost, while IRS21844 trades pin count and package size for integrated bootstrap support and tighter industrial-grade UVLO - making IR2301 optimal for compact, high-performance half-bridge designs needing 3.3 V logic and minimal delay skew.

FAQ

Can IR2301 drive SiC MOSFETs directly?

Yes - IR2301 can drive SiC MOSFETs with gate charge ≤35 nC and threshold voltage ≥2.5 V. Its 200 mA peak source/sink current, 50 V/ns dV/dt immunity, and 220 ns rise time meet typical SiC gate requirements at 100 kHz switching. External gate resistors must be selected to limit dv/dt per device datasheet limits.

What is the minimum bootstrap capacitor value for IR2301 in 20 kHz operation?

For 20 kHz PWM with 50% duty cycle and 15 V VBS, a 0.22 µF ceramic capacitor with ≤100 mΩ ESR is recommended. This ensures <1.5 V droop per cycle given typical 60 µA quiescent VBS current and 200 mA peak charging demand, maintaining UVLO margin above 10.5 V.

Does IR2301 require external level-shifting components for high-side control?

No - IR2301 integrates a monolithic high-voltage level shifter (HVIC) that eliminates external optocouplers, pulse transformers, or isolated DC/DC converters. The floating channel operates autonomously with only VB, VS, and HO connections required for high-side gate drive.

How does IR2301 handle negative VS transients?

IR2301 tolerates VS transients down to −5 V relative to COM (per Note 1), supported by internal clamp structures and latch-immune design. During negative excursions, logic remains latched and outputs disable until VS recovers within −5 V to +600 V range - preventing false turn-on in hard-commutated or resonant circuits.
