Product details

Overview

IR21362S 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 11.5–20V VCC supply, features in-phase high-side output logic (vs. out-of-phase in IR2136), includes programmable fault-clear delay via RCIN, and delivers matched 400ns/380ns turn-on/turn-off propagation delays. It is used in industrial motor inverters driving BLDC or PMSM motors.

For engineers reviewing the IR21362S datasheet, IR21362S pinout, IR21362S application, or IR21362S equivalent, key selection criteria include its 600V floating channel rating, 3.3V logic compatibility, undervoltage lockout thresholds (10.4V/9.4V), over-current shutdown with automatic RCIN-based recovery, and in-phase high-side output behavior distinguishing it from IR2136/IR21363 families.

Technical Context

The IR21362S integrates three isolated high-side level shifters with HVIC technology, enabling robust operation at VS = COM +600V while maintaining logic integrity during fast dV/dt transients. Its shoot-through prevention logic enforces deadtime ≥220ns between complementary HO/LO outputs per channel, and input noise filters provide 100–200ns pulse rejection on HIN/LIN/EN pins.

Unlike IR2136/IR21363, the IR21362S implements in-phase high-side output logic-HOx follows HINx directly-simplifying PWM timing in synchronous rectification or certain FOC topologies. Its ITRIP comparator has 0.46V threshold with 70mV hysteresis, and FAULT is open-drain with 50–100Ω on-resistance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BS Range	11.5–20V: sets minimum bootstrap capacitor voltage needed to sustain high-side drive under load
Propagation Delay (t_on/t_off)	400ns/380ns typ.: enables reliable operation up to ~500kHz switching with predictable timing margins
UVLO Thresholds (V_CC)	10.4V (rising), 9.4V (falling): prevents erratic operation during brown-out or startup
I_TRIP Threshold	0.46V typ. with 70mV hysteresis: allows precise current sensing using low-value shunt resistors (e.g., 5 mΩ @ 92A)
VS Offset Rating	−5V to +600V vs. COM: supports high-side switching in 400–600V DC bus systems
Logic Compatibility	3.3V CMOS/LSTTL: interfaces directly with modern microcontrollers without level-shifting
Output Drive Strength	200mA source / 350mA sink pulsed: drives typical 1–2nF gate capacitances with <125ns rise time

Pinout & Package

IR21362S is available in 28-lead SOIC package (surface-mount) with thermal pad exposed on underside for enhanced power dissipation (R_thJA = 78°C/W). Pin assignments are validated per Infineon PD60166 revS datasheet.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Low-side and logic supply input	Provides power for internal logic, level shifters, and low-side drivers; must be decoupled near pin
VSS	Logic ground reference	Return path for logic circuits; separate from power ground (COM) to minimize noise coupling
COM	Power ground reference	Common return for all low-side outputs (LO1–LO3); connects to system power ground
HIN1–HIN3	High-side input signals	CMOS-compatible inputs controlling HO1–HO3; in-phase response distinguishes IR21362S from IR2136
LIN1–LIN3	Low-side input signals	CMOS-compatible inputs controlling LO1–LO3; out-of-phase relative to LINx
HO1–HO3	High-side gate drive outputs	Floating outputs referenced to VS1–VS3; drive gates of high-side N-MOSFETs/IGBTs
LO1–LO3	Low-side gate drive outputs	Ground-referenced outputs driving low-side switches; sink/source capability supports fast turn-off
VS1–VS3	High-side floating supply return	Source/emitter node of high-side switch; defines local ground for corresponding HOx/VBx stage
VB1–VB3	High-side floating supply input	Connects to bootstrap capacitor positive terminal; supplies gate drive for HOx outputs
ITRIP	Over-current sense input	Monitors voltage across external shunt; triggers shutdown when >0.46V (hysteresis prevents chatter)
RCIN	Fault clear timing input	Accepts RC network to set auto-clear delay (1.3–2ms typ.); resets FAULT after overcurrent clears
EN	Global enable input	Active-high signal that disables all six outputs simultaneously when pulled low
FAULT	Open-drain fault indicator	Asserts low on UVLO or over-current; requires external pull-up; indicates latched or auto-cleared condition

Key Features

Feature	Design Value
In-phase high-side output logic	HOx directly follows HINx state-eliminates need for external inversion in synchronous rectifier or certain FOC schemes
Programmable fault auto-clear	RCIN pin accepts external R-C network to set precise recovery delay (1.3–2ms), enabling graceful restart after transient overloads
Matched propagation delay across channels	≤70ns max mismatch (ton/toff) ensures balanced timing in 3-phase PWM, reducing torque ripple in motor drives
Cross-conduction prevention logic	Hardware-enforced deadtime ≥220ns prevents shoot-through even with overlapping HIN/LIN edges
dV/dt immune floating channel	Withstands >50V/ns common-mode transients on VS nodes-critical for reliability in noisy 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
IR2136S	Out-of-phase HO logic; lower VCC UVLO (8.9V/8.2V); same 400ns/380ns delays	Requires inverted HIN signals; less suitable for synchronous rectification or certain FOC implementations	Select when legacy design uses out-of-phase timing or lower supply voltage margin is acceptable
IR21363S	Out-of-phase HO logic; higher VCC UVLO (11.2V/11.0V); identical pinout and timing	Better suited for 12V auxiliary rails; not compatible with 11.5V minimum VCC requirement of IR21362S	Choose for new designs targeting 12V systems where tighter UVLO margin improves robustness against rail droop

Compared with IR2136S and IR21363S, the IR21362S uniquely offers in-phase high-side output behavior and a 11.5V minimum VCC-making it optimal for 12V-derived supplies with marginal dropout, while eliminating external inverters in synchronous rectifier topologies.

FAQ

What is the purpose of the RCIN pin on the IR21362S?

The RCIN pin sets the automatic fault-clear delay time using an external resistor-capacitor network. When an over-current event triggers shutdown, the FAULT pin remains asserted until RCIN voltage exceeds 8V, which occurs after a time constant defined by R × C. Typical values (e.g., 2 MΩ + 1 nF) yield 1.3–2 ms recovery, allowing transient faults to clear without system reset.

How does the IR21362S differ from the IR2136S in high-side logic behavior?

The IR21362S provides in-phase high-side outputs (HOx follows HINx), whereas the IR2136S delivers out-of-phase outputs (HOx is inverted relative to HINx). This eliminates the need for external inverters in synchronous rectification or certain field-oriented control schemes, simplifying PCB layout and firmware timing logic.

Can the IR21362S drive both MOSFETs and IGBTs?

Yes-the IR21362S is explicitly designed for both N-channel MOSFETs and IGBTs in 3-phase bridge configurations. Its 200mA source / 350mA sink peak output current, 125ns rise time, and 600V VS rating accommodate typical gate charge requirements and blocking voltages of 600–650V devices used in industrial inverters.

What is the function of the EN (Enable) pin?

The EN pin is an active-high global enable input that disables all six gate outputs (HO1–HO3, LO1–LO3) when driven low. It provides hardware-level emergency shutdown independent of input signals or fault conditions, enabling integration with system-level safety monitors or watchdog circuits.
