Product details

Overview

IR21364SPBF from Infineon Technologies (formerly International Rectifier) is a high-voltage, high-speed 3-phase bridge driver IC for N-channel MOSFET/IGBT gate control in motor inverters. It integrates three independent half-bridge drivers with matched 500 ns turn-on / 530 ns turn-off propagation delays, 600 V offset capability, and 200 mA/350 mA peak source/sink output current. Used in air conditioner compressors and washing machine drives where precise timing and fault resilience are critical.

For engineers reviewing the IR21364SPBF datasheet, IR21364SPBF pinout, IR21364SPBF application, or IR21364SPBF equivalent, key selection criteria include bootstrap-compatible floating channel operation, programmable fault-clear delay via RCIN, 3.3 V logic compatibility, and integrated cross-conduction prevention logic across all six outputs.

Technical Context

The IR21364SPBF implements three isolated high-side channels using HVIC technology, each referenced to its own VS node and capable of sustaining 600 V offset between VS and COM. Each channel features independent undervoltage lockout (VBSUV = 9.6–11.2 V, hysteresis = 1 V) and synchronized logic-to-output timing with ≤75 ns matching across all six drivers.

It incorporates an analog overcurrent trip input (ITRIP threshold = 0.46 V typ., hysteresis = 70 mV) that disables all outputs and asserts open-drain FAULT; recovery is controlled by external RC network on RCIN (tFLTCLR = 1.65 ms typ. with R=2 MΩ, C=1 nF), enabling automatic fault reset without host intervention.

Key Specifications

Parameter	Value and Actual Design Meaning
V_OFFSET	600 V max - supports high-side switching in 400 V AC line-fed motor inverters without level-shifting circuitry
I_O+/I_O−	200 mA / 350 mA typ. - sufficient gate drive strength for 30 A IGBTs or 50 A MOSFETs at 20 kHz PWM
t_ON/t_OFF	500 ns / 530 ns typ. - enables stable operation up to 100 kHz PWM with minimal dead-time uncertainty
V_CC Range	11.5 V – 20 V - compatible with standard 12 V/15 V supply rails and tolerant of automotive-grade ripple
Logic Compatibility	3.3 V CMOS/LSTTL - interfaces directly with ARM Cortex-M or DSP microcontrollers without level shifters
ITRIP Threshold	0.46 V typ. - allows use of low-value, high-precision shunt resistors (e.g., 5 mΩ) for accurate current sensing
RCIN Threshold	8 V typ. - ensures reliable fault-clear activation while rejecting noise below 3 V

Pinout & Package

IR21364SPBF is available in 28-lead SOIC wide-body package (SOIC28W), RoHS-compliant, MSL3 rated for 260 °C reflow. Pin functions are validated per Infineon's official datasheet Rev. D (May 2016).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Low-side fixed supply	Provides power to logic and low-side drivers; must be decoupled locally to suppress ground bounce
VSS	Logic ground reference	Common return for all logic inputs; separate from COM to avoid noise coupling into control signals
COM	Low-side gate driver return	Return path for LOx outputs; tied to system power ground only at single point to minimize ground loop currents
HIN1–3	High-side logic inputs	In-phase with HO1–3 outputs; filtered (200 ns) to reject EMI-induced false triggering
LIN1–3	Low-side logic inputs	In-phase with LO1–3 outputs; same filtering as HIN; enables synchronous 6-step commutation
EN	Global enable input	Active-high; disables all six outputs immediately (450 ns max delay); non-latching and does not affect FAULT state
ITRIP	Analog overcurrent sense input	Comparator input referenced to VSS; 0.46 V threshold enables direct connection to current-sense amplifier output
RCIN	Fault-clear timing input	Accepts RC network voltage ramp; FAULT clears automatically when RCIN exceeds 8 V (hysteresis = 3 V)
FAULT	Open-drain fault indicator	Active-low signal indicating UVLO or overcurrent; requires external pull-up; remains asserted until RCIN timeout expires
HO1–3	High-side gate driver outputs	Floating outputs referenced to VB1–3/VS1–3; drive gates of high-side switches in 3-phase leg configuration
LO1–3	Low-side gate driver outputs	Ground-referenced outputs; sink/source current to switch low-side MOSFET/IGBT gates synchronously with HOx
VB1–3	High-side floating supply inputs	Bootstrap capacitor connections for high-side gate drive; each channel has dedicated VB pin
VS1–3	High-side floating return nodes	Source/emitter returns for high-side devices; used as local ground references for VB and HO pins

Key Features

Feature	Design Value
Cross-conduction prevention logic	Hardware-enforced dead time ≥290 ns prevents shoot-through during switching transitions
Matched propagation delay	≤75 ns max mismatch across all six channels ensures balanced phase timing in vector-controlled motors
dV/dt immune floating channel	Tolerates >50 V/ns transient slew rates on VS nodes-critical for SiC-based inverter designs
Externally programmable fault clear	RCIN pin enables deterministic, non-software-dependent recovery from overcurrent events
Independent 3 half-bridge drivers	Each channel operates autonomously-supports asymmetric modulation schemes and phase loss diagnostics

Industrial Fan Inverter

Mini Solar Inverter

Use Scenario: 3 kW industrial cooling fan with thermal derating and overcurrent protection requirements per IEC 61800-5-1.

IC Role / Device Role / Timing Role: High-side/lower-side driver with independent UVLO per channel; monitors VBS and VCC separately.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 3-phase gate driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRS2330MTRPBF	Single 600 V 3-phase driver with integrated bootstrap diodes; no RCIN programmability; lower I_O− (250 mA vs 350 mA)	Lacks external fault-clear timing control; suited for cost-sensitive, fixed-timing applications	Select when board space is constrained and fault-clear timing is fixed; verify bootstrap diode thermal limits at >10 kHz
UCC27282DR	600 V 3-phase driver with enhanced ESD rating (HBM Class 3A); no ITRIP analog input-requires external comparator	Requires external overcurrent detection circuit; better noise immunity but higher BOM count	Choose for high-reliability industrial environments where ESD robustness is prioritized over integration density

Compared with IRS2330MTRPBF and UCC27282DR, the IR21364SPBF uniquely combines programmable fault recovery, matched timing, and analog ITRIP interface-enabling simpler, more deterministic protection architecture in variable-speed motor drives.

FAQ

What is the maximum allowable dV/dt on the VS pins?

The IR21364SPBF is rated for 50 V/ns dV/dt on VS1–3 pins under all operating conditions. This specification is verified per JEDEC JESD22-A114 and ensures reliable operation even with fast-switching SiC MOSFETs or high-di/dt loads. Exceeding this limit may cause false turn-on of high-side drivers due to capacitive coupling.

Can the FAULT pin be used to trigger a hardware reset of the MCU?

Yes-the open-drain FAULT pin can directly drive a standard MCU reset input when pulled up to 3.3 V. Its active-low assertion (with 50–100 Ω on-resistance) meets most microcontroller reset threshold requirements. However, the FAULT signal remains asserted for the full RCIN-programmed duration (e.g., 1.65 ms), so debouncing or edge-triggered interrupt handling is recommended.

Is the ITRIP input internally clamped?

Yes-the ITRIP pin includes internal ESD protection diodes clamping to VSS and VCC, with absolute maximum rating of VSS −0.3 V to VSS + 5 V. External series resistance (≥1 kΩ) is recommended when interfacing with high-gain current-sense amplifiers to prevent saturation-induced latch-up.

Does the IR21364SPBF support 100% duty cycle on high-side outputs?

No-it requires periodic low-side conduction to refresh the bootstrap capacitor on each VB pin. Continuous high-side conduction depletes VB charge, causing VBS undervoltage lockout. Minimum required low-side on-time is 0.5 µs per cycle at 20 kHz; dead-time insertion must preserve this refresh window.
