Product details

Overview

IR21368JTRPBF from Infineon Technologies is a high-voltage, high-speed 3-phase bridge driver IC with three independent half-bridge gate drivers for N-channel MOSFETs and IGBTs. It operates up to +600V VS offset, supports 10–20V VCC supply, features 400ns/380ns typical turn-on/turn-off propagation delay, 3.3V logic compatibility, and integrated over-current shutdown with RCIN-programmable fault-clear delay. It is used in industrial motor inverters driving BLDC or PMSM motors.

For engineers reviewing the IR21368JTRPBF datasheet, IR21368JTRPBF pinout, IR21368JTRPBF application, or IR21368JTRPBF equivalent, key selection criteria include its 600V floating channel rating, matched propagation delays across all six outputs, undervoltage lockout thresholds (8.9V/8.2V), 4.3V current-sense trip threshold, and SOIC-28 lead-free package compatibility with bootstrap gate drive topologies.

Technical Context

The IR21368JTRPBF integrates three high-side and three low-side drivers using proprietary HVIC technology, enabling monolithic construction with dV/dt immunity and negative transient tolerance. Its floating channels use level-shifting architecture referenced to VS1–VS3, supporting high-side operation up to 600V with VB1–VB3 supplies.

It implements cross-conduction prevention logic per channel, fixed deadtime (~290ns), and shoot-through protection via internal latching. The ITRIP input triggers simultaneous shutdown of all six outputs when exceeding 4.3V, with fault recovery governed by an external RC network on RCIN (1.65ms typical clear time).

Key Specifications

Parameter	Value and Actual Design Meaning
V_BS Range	10–20V: sets minimum gate drive voltage margin for high-side N-MOSFETs under bootstrap decay.
V_CC UVLO Threshold	8.9V (rising), 8.2V (falling): prevents erratic switching during brown-out conditions in low-voltage logic supply.
I_TRIP Threshold	4.3V: defines over-current detection level at external sense resistor; enables fast shutdown before power device failure.
t_on/t_off	400ns/380ns typ.: ensures precise PWM timing alignment across all three phases in high-frequency motor control.
Logic Compatibility	3.3V CMOS/LSTTL: allows direct interface with modern microcontrollers without level-shifting circuitry.
V_S Offset Rating	600V max: supports high-voltage inverter stages in 400V AC line-fed or battery-based industrial drives.
Package	28-Lead SOIC (RoHS-compliant, PbF): provides thermal performance (R_thJA = 78°C/W) suitable for convection-cooled PCB layouts.

Pinout & Package

IR21368JTRPBF is housed in a 28-lead SOIC package with exposed pad for thermal enhancement. Pin assignments are validated per Infineon PD60166 revS datasheet and confirmed on official distributor landing pages (Digi-Key, Mouser).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Low-side and logic supply input	Provides regulated 10–20V power for internal logic, level shifters, and low-side drivers.
VSS	Logic ground reference	Common return for all logic inputs (HIN/LIN/EN/ITRIP/RCIN); must be tied to system digital ground.
COM	Power ground reference	Return path for low-side output currents (LO1–LO3); connects to inverter leg source nodes.
HIN1–HIN3	High-side PWM inputs	CMOS-compatible inputs controlling HO1–HO3; inverted output phase relative to input.
LIN1–LIN3	Low-side PWM inputs	CMOS-compatible inputs controlling LO1–LO3; inverted output phase relative to input.
HO1–HO3	High-side gate drive outputs	Drive gates of high-side N-MOSFETs/IGBTs referenced to VS1–VS3; require bootstrap capacitors.
LO1–LO3	Low-side gate drive outputs	Drive gates of low-side N-MOSFETs/IGBTs referenced to COM; non-inverting outputs.
VS1–VS3	Floating high-side source references	Connect to source terminals of high-side switches; define local ground for each high-side driver.
VB1–VB3	Floating high-side supply inputs	Accept bootstrap-supplied voltage (VSx + 10–20V); enable gate drive above VSx potential.
FAULT	Open-drain fault indicator	Pulls low on UVLO or over-current; requires external pull-up; signals shutdown condition to MCU.
ITRIP	Over-current sense input	Monitors voltage across external shunt; trips at 4.3V to disable all outputs within 750ns.
RCIN	Fault auto-clear timing input	Accepts RC network (e.g., 2MΩ + 1nF) to set ~1.65ms delay before FAULT recovers after ITRIP clears.
EN	Global enable/disable input	Active-high signal that forces all six outputs low when deasserted; overrides PWM inputs.

Key Features

Feature	Design Value
Matched propagation delay	≤70ns max mismatch across all six outputs ensures synchronized switching and minimizes torque ripple in 3-phase motors.
Cross-conduction prevention logic	Hardware-enforced deadtime (~290ns) and latch-based shoot-through blocking eliminate need for external timing circuits.
Externally programmable fault clear	RCIN pin accepts passive RC network to set precise fault recovery delay-enables safe restart after over-current events.
3.3V logic compatible inputs	Direct interface with ARM Cortex-M, TI C2000, or ST STM32 MCUs without level translators, reducing BOM count.
dV/dt immune floating channel	Withstands >50V/ns transients on VS pins, enabling robust operation in noisy high-power inverter environments.

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
IR2136JTRPBF	Same SOIC-28 package; lower ITRIP threshold (0.46V) and higher UVLO (8.9V/8.2V), but lacks 3.3V logic compatibility (requires ≥5V inputs).	Used in legacy 5V microcontroller-based inverters where current sensing uses low-value shunts (<10mΩ).	Select when interfacing with older 5V logic and needing tighter current-sense resolution at low voltages.
IRS2330JPbF	SOIC-28, 600V rating, 3.3V logic compatible, but no RCIN fault-clear programming; FAULT is latched until EN reset.	Suitable for cost-sensitive applications where fault recovery is managed externally via MCU GPIO.	Choose when simplified fault handling suffices and RCIN programmability is not required for safety-critical restart timing.

Compared with IR2136JTRPBF, IR21368JTRPBF adds 3.3V logic support and higher ITRIP threshold for noise-immune current sensing; versus IRS2330JPbF, it offers deterministic RCIN-based fault recovery critical for motor stall recovery in industrial automation.

FAQ

What is the maximum allowable dV/dt on the VS pins of IR21368JTRPBF?

The absolute maximum dV/dt rating is 50 V/ns, verified per Infineon PD60166 revS test conditions. This immunity is achieved through proprietary HVIC isolation and internal level-shifter design, enabling reliable operation in fast-switching SiC or GaN-based inverters where high di/dt induces large transient coupling on high-side source nodes.

Can IR21368JTRPBF drive both MOSFETs and IGBTs?

Yes-it is explicitly rated for both N-channel power MOSFETs and IGBTs, as confirmed in the device description and functional block diagram. Its 200mA peak high-side and 350mA peak low-side pulsed output currents meet gate charge requirements for typical 30A–60A discrete switches in 3-phase bridges up to 600V bus voltage.

How does the RCIN pin determine fault-clear timing?

RCIN sets fault recovery delay via an external RC network: t_FLTCLR ≈ 1.1 × R × C. With R = 2 MΩ and C = 1 nF, typical clear time is 1.65 ms. The internal comparator monitors RCIN voltage; once it exceeds 8 V (at VCC = 15 V), the FAULT pin returns to high-impedance, re-enabling outputs if no active fault remains.

Is the IR21368JTRPBF pin-compatible with other IR2136x variants?

No-while sharing the same SOIC-28 package and core pinout (VCC, COM, VSS, HIN/LIN, HO/LO, VS/VB, FAULT, ITRIP, RCIN, EN), differences in logic thresholds (e.g., VIH/VIL), UVLO levels, and ITRIP voltage mean direct substitution may cause incorrect enable/disable behavior or false over-current triggering without circuit review.
