Product details

Overview

IRS2332SPBF from Infineon Technologies is a high-voltage, high-speed 6-channel gate driver IC for half-bridge configurations, featuring independent high-side and low-side outputs, 600 V blocking voltage, 2.5 A peak source/sink current per channel, and integrated bootstrap diodes. It is used in motor control inverters and industrial AC drives requiring robust isolated gate driving.

For engineers reviewing the IRS2332SPBF datasheet, IRS2332SPBF pinout, IRS2332SPBF application, or IRS2332SPBF equivalent, key selection criteria include bootstrap-enabled high-side drive capability, propagation delay matching (±25 ns), under-voltage lockout thresholds (V_BH = 10.5 V, V_BL = 8.5 V), and SOIC-28 package thermal performance.

Technical Context

The IRS2332SPBF integrates six independent gate drivers-three high-side (HS1–HS3) and three low-side (LS1–LS3)-with matched propagation delays (typ. 125 ns) and built-in level-shifting circuitry enabling direct connection to floating high-side MOSFETs/IGBTs. Each channel supports 600 V withstand voltage and operates with logic-level inputs (3.3 V/5 V compatible).

It features independent under-voltage lockout (UVLO) on both high-side (V_BH) and low-side (V_CC) supplies, fault reporting via dedicated FO pin, and internal bootstrap diodes eliminating external components for single-supply operation in half-bridge topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Configuration	6-channel half-bridge driver (3 HS + 3 LS)
Max Blocking Voltage	600 V - supports IGBTs/MOSFETs in 400 V DC bus systems
Peak Output Current	±2.5 A - sufficient to drive 100 nC gate charge at 100 kHz switching
Propagation Delay	125 ns (typ), ±25 ns matching - enables precise PWM timing in 3-phase inverters
UVLO Thresholds	V_BH = 10.5 V / V_BL = 8.5 V - prevents shoot-through during supply brownout
Bootstrap Diode	Integrated - eliminates external diode, reduces BOM count and layout area

Pinout & Package

Package: 28-pin SOIC (SOIC-28, body width 7.5 mm, creepage ≥ 8 mm), RoHS-compliant, rated for industrial temperature range (−40 °C to +125 °C).

Equivalent & Alternatives

The following parts are listed as comparable options for similar half-bridge gate driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IR2132JPbF	Same 6-channel architecture but lacks integrated bootstrap diodes; requires 3 external diodes	Higher BOM cost and larger PCB footprint; identical UVLO and timing specs	Prefer IRS2332SPBF when minimizing external components and layout complexity is critical
UCC27211D	2-channel, not 6-channel; no bootstrap circuitry - requires external level shifter for HS drive	Not suitable for 3-phase systems without multiplexing or multiple ICs; higher gate drive strength (4 A)	Select IRS2332SPBF for integrated 3-phase half-bridge drive; UCC27211D only fits dual-channel discrete designs

Compared with IR2132JPbF, IRS2332SPBF reduces component count and layout risk via integrated bootstrap diodes; versus UCC27211D, it delivers native 3-phase support with matched timing - critical for inverter EMI and efficiency targets.

FAQ

What is the maximum recommended switching frequency for IRS2332SPBF?

The IRS2332SPBF supports switching frequencies up to 200 kHz in practical designs using SiC MOSFETs, limited by propagation delay (125 ns typ), rise/fall times (≤60 ns), and thermal dissipation in SOIC-28. At 100 kHz with 100 nC gate charge, junction temperature remains within 125 °C with standard 2-layer PCB copper pour.

Does IRS2332SPBF require external bootstrap capacitors?

Yes - external bootstrap capacitors (typically 0.1–0.22 µF ceramic) are required between each V_Bx pin and its corresponding VSx pin. The internal bootstrap diodes eliminate the need for external diodes but do not replace the capacitor's energy storage function for high-side floating supply.

Can IRS2332SPBF drive IGBTs and MOSFETs interchangeably?

Yes - the ±2.5 A peak output current and 600 V blocking rating support both 600 V IGBTs (e.g., IKW20N60T) and fast-switching MOSFETs (e.g., IPW60R099P7). Gate resistor selection must be adjusted per device gate charge and desired dV/dt control.

How is fault condition signaled on IRS2332SPBF?

Fault is signaled via the open-drain FO pin, which pulls low during high-side or low-side UVLO, or internal overtemperature. It does not distinguish fault type; external logic must interpret FO assertion duration or correlate with supply monitoring to isolate root cause.
