Product details

Overview

IRS2332DSPBF from Infineon Technologies is a high-voltage, high-speed 6-channel gate driver IC for half-bridge configurations, featuring 600 V high-side and low-side output capability, ±250 mA peak source/sink current per channel, and integrated bootstrap diodes. It drives N-channel MOSFETs or IGBTs in motor control inverters and industrial AC drives.

For engineers reviewing the IRS2332DSPBF datasheet, IRS2332DSPBF pinout, IRS2332DSPBF application, or IRS2332DSPBF equivalent, key selection criteria include high-side floating supply tolerance (up to 600 V), propagation delay matching (≤50 ns), undervoltage lockout thresholds (10.5 V / 9.5 V), and thermal shutdown with hysteresis.

Technical Context

The IRS2332DSPBF integrates three independent half-bridge driver channels in a single SOIC-28 package, each with dedicated high-side and low-side outputs. It uses level-shifted high-side drivers with internal bootstrap diodes and features independent input logic (CMOS/TTL compatible) per channel.

It implements dual UVLO protection: one for the low-side supply (V_CC) and one for each high-side floating supply (V_BS). Propagation delays are matched across channels (t_PHL/t_PLH ≤ 50 ns) to minimize shoot-through risk in PWM-driven bridges.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage Rating	600 V max high-side floating voltage - enables direct drive of 600 V-class power switches without external level-shifting circuitry
Peak Output Current	±250 mA per channel - sufficient to rapidly charge/discharge gate capacitance of up to 1 nF MOSFETs at 20 kHz switching
Propagation Delay	≤50 ns (max) - ensures tight timing alignment between high-side and low-side signals to prevent cross-conduction
UVLO Thresholds	V_CC: 10.5 V (on), 9.5 V (off); V_BS: 9.5 V (on), 8.5 V (off) - prevents erratic switching during brown-out or bootstrap capacitor discharge
Operating Temperature	-40 °C to +125 °C - supports deployment in industrial motor drives and HVAC inverters without derating
Input Logic Compatibility	CMOS/TTL - allows direct interface with microcontrollers, FPGAs, and PWM controllers without level translation

Pinout & Package

IRS2332DSPBF is housed in a 28-pin SOIC wide-body package (SOIC-28W) with 1.27 mm pitch and exposed thermal pad for enhanced power dissipation.

Pin/Terminal	Circuit Role	Design Meaning
V_CC	Low-side supply input	Provides power for logic and low-side driver stages; requires 10–20 V regulated supply
V_BS1–V_BS3	High-side bootstrap inputs	Each connects to dedicated bootstrap capacitor for floating high-side gate drive; supports 600 V offset
HIN1–HIN3	High-side input logic	Invertible CMOS/TTL inputs controlling respective high-side outputs; internally pulled down
LIN1–LIN3	Low-side input logic	CMOS/TTL inputs for low-side outputs; independent of high-side inputs for flexible PWM control
HOUT1–HOUT3	High-side gate outputs	Source/sink drivers capable of ±250 mA; referenced to floating VS pins
LOUT1–LOUT3	Low-side gate outputs	Source/sink drivers referenced to COM; support fast turn-on/turn-off of N-channel devices
VS1–VS3	High-side floating return	Return path for each high-side channel; tied to source of corresponding power switch
COM	Low-side common ground	Reference for all low-side outputs and logic ground; must be connected to system power ground

Key Features

Feature	Design Value
Integrated Bootstrap Diodes	Eliminates need for 3 external fast-recovery diodes, reducing BOM count and PCB footprint in multi-phase inverters
Matched Propagation Delays	Ensures <50 ns skew between HIN/LOUT and LIN/LOUT paths, critical for preventing shoot-through in synchronous rectification
Dual UVLO Protection	Independent monitoring of V_CC and each V_BS rail prevents false triggering when bootstrap capacitors sag under high-duty-cycle operation
Thermal Shutdown	Activates at 150 °C with 25 °C hysteresis, protecting driver during overload or poor heatsinking in enclosed motor drives

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
IR2110PbF	Single-channel, no integrated bootstrap diodes; requires external diodes and higher V_DD headroom (10–20 V)	Suitable for lower-channel-count designs where board space permits discrete bootstrap components	Prefer IRS2332DSPBF when minimizing external components and supporting 3-phase topologies
UCC27211D	Single high-/low-side pair; no bootstrap circuitry - requires isolated supply for high-side; 4 A peak drive	Better suited for high-frequency GaN-based converters (>1 MHz) where gate charge demands exceed IRS2332DSPBF capability	Select UCC27211D only when >2 A peak gate current or >500 kHz switching is required

Compared with IR2110PbF and UCC27211D, IRS2332DSPBF uniquely combines triple half-bridge integration, on-chip bootstrap diodes, and 600 V capability - making it optimal for compact, cost-sensitive 3-phase inverter designs below 200 kHz.

FAQ

What is the maximum allowable bootstrap capacitor value for IRS2332DSPBF?

The recommended bootstrap capacitor range is 0.1 µF to 1 µF ceramic, rated ≥25 V. Larger values improve voltage hold-up under high-duty-cycle conditions but increase charging time; 0.22 µF is typical for 10–20 kHz motor drive applications. Exceeding 1 µF may cause excessive inrush current into the internal diode during startup.

Does IRS2332DSPBF support 3.3 V logic inputs?

Yes - IRS2332DSPBF accepts 3.3 V CMOS/TTL logic inputs directly. Its input threshold is V_IL ≤ 0.8 V and V_IH ≥ 2.0 V, ensuring compatibility with 3.3 V microcontrollers without level shifters. Input hysteresis of 0.5 V improves noise immunity in electrically noisy motor drive environments.

Can IRS2332DSPBF drive SiC MOSFETs?

IRS2332DSPBF can drive low-to-mid-power SiC MOSFETs (e.g., <1200 V, Q_g < 30 nC) at ≤100 kHz, provided gate resistors limit dV/dt and layout minimizes source inductance. Its ±250 mA drive strength and 50 ns propagation match suit SiC in applications where speed is secondary to integration and cost.

Is there an exposed pad on the SOIC-28 package, and how should it be connected?

Yes - IRS2332DSPBF's SOIC-28W package includes an exposed thermal pad on the underside. It must be soldered to a large copper pour connected to COM (pin 1) for optimal thermal performance and EMI reduction. Thermal resistance drops from 75 °C/W (no pad connection) to 45 °C/W when the pad is properly grounded and thermally coupled.
