Infineon Technologies IRS2330SPBF

Overview

IRS2330SPBF from Infineon Technologies is a high-voltage, high-speed half-bridge gate driver IC designed for driving N-channel power MOSFETs and IGBTs in motor control, UPS, and DC-AC inverters. It features independent high-side and low-side outputs, 600 V high-side floating capability, 150 ns propagation delay matching, and integrated dead-time generation with 500 ns typical value.

For engineers reviewing the IRS2330SPBF datasheet, IRS2330SPBF pinout, IRS2330SPBF application, or IRS2330SPBF equivalent, key selection criteria include bootstrap-based high-side drive compatibility, matched propagation delays for synchronous switching, under-voltage lockout thresholds (V_BH = 10.2 V, V_BL = 8.7 V), and SOIC-28 package thermal performance in 40–100 kHz PWM systems.

Technical Context

The IRS2330SPBF integrates dual-channel level-shifting drivers with independent input logic (IN_H/IN_L) and output enable (EN) control. Its high-side driver uses a floating channel with internal diode-clamped bootstrap supply interface and operates up to 600 V DC bus potential.

It implements non-overlapping logic with built-in dead-time insertion between high-side and low-side outputs to prevent shoot-through. UVLO protection is implemented separately on both high-side (V_BH) and low-side (V_BL) supplies with hysteresis of 1.5 V.

Key Specifications

Pinout & Package

FAQ

What is the minimum bootstrap capacitor value required for stable IRS2330SPBF operation at 50 kHz?

A 0.1 µF ceramic capacitor rated ≥25 V is recommended for 50 kHz operation with ≤10% voltage droop per cycle. The capacitor must be placed within 5 mm of V_BS and COM pins to minimize loop inductance. Typical charge current is 1.2 mA average; insufficient capacitance causes V_BS UVLO triggering and output disable.

Can IRS2330SPBF drive IGBTs with gate charge exceeding 100 nC?

Yes, but only with external gate resistors limiting peak current to ≤2 A and ensuring gate voltage slew rate stays within 5 V/ns. For 100 nC IGBTs, use R_G = 10 Ω (turn-on) and 15 Ω (turn-off); thermal derating applies above 40°C ambient due to SOIC-28W power dissipation limits.

Does IRS2330SPBF support 3.3 V logic input levels?

No - IRS2330SPBF requires TTL/CMOS logic thresholds: V_IL ≤ 0.8 V and V_IH ≥ 2.5 V with V_CC ≥ 10 V. Direct 3.3 V MCU interfacing is possible only if the MCU's VOH exceeds 2.5 V at I_OH = 1 mA; otherwise, a level-shifting buffer is required.

How does the internal dead time affect minimum achievable duty cycle in PWM control?

The fixed 500 ns dead time imposes a 5% minimum off-time penalty at 100 kHz (10 µs period), limiting practical minimum duty cycle to ~5% for symmetric PWM. Asymmetric control via independent HIN/LIN allows sub-5% effective duty by overlapping inactive periods, preserving regulation resolution in digital PWM implementations.
