Product details

Overview

IR21362J 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 or IGBTs. It operates up to +600V on the floating high-side channels, features 3.3V logic compatibility, 400ns typical turn-on propagation delay, and in-phase high-side output logic (distinguishing it from IR2136/IR21363). It is used in motor control inverters for industrial AC drives and servo systems.

For engineers reviewing the IR21362J datasheet, IR21362J pinout, IR21362J application, or IR21362J equivalent, key selection considerations include its 11.5–20V VCC/VBS operating range, programmable fault-clear delay via RCIN, undervoltage lockout thresholds (10.4V/9.4V), and matched propagation delays across all six outputs.

Technical Context

The IR21362J integrates proprietary HVIC technology for monolithic high-voltage isolation between low-side (COM-referenced) and high-side (VS-referenced) driver stages. Its floating channel supports bootstrap operation with ±50 V/ns dV/dt immunity and logic-level inputs compatible with CMOS/LSTTL down to 3.3V.

It implements cross-conduction prevention logic per channel, external current-sense-based over-current shutdown (via ITRIP), and an open-drain FAULT signal with automatic recovery after RCIN-programmed delay. High-side outputs are in-phase with HIN inputs - a functional distinction from IR2136/IR21363 - enabling direct PWM control without external inversion.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BS Range	11.5 V to 20 V - sets minimum bootstrap supply voltage for reliable high-side gate drive at full load
Propagation Delay (t_on/t_off)	400 ns / 380 ns typ. - enables precise timing control in >20 kHz PWM motor drives
UVLO Thresholds (V_CC/V_BS)	10.4 V (rising), 9.4 V (falling) - prevents erratic switching during brown-out or startup
I_TRIP Threshold	0.46 V typ. - allows use of low-value, low-power sense resistors (e.g., 5 mΩ @ 100 A)
Logic Compatibility	3.3 V CMOS/LSTTL - interfaces directly with modern microcontrollers and FPGAs without level-shifting
dV/dt Immunity	50 V/ns - maintains stable operation during fast-switching transients in 600 V bus applications
Output Drive Current	200 mA (source), 350 mA (sink) - sufficient to drive 10 nF gate capacitance with <100 ns rise/fall times

Pinout & Package

IR21362J is supplied in a 28-lead PDIP package with through-hole mounting and standard 0.3" wide body. Pin assignments follow JEDEC MS-013AC, with COM as logic ground reference and VS1/VS2/VS3 as high-side floating source terminals.

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 circuitry; must be connected to system COM with low-inductance trace
COM	Power ground reference	Common return for all low-side outputs (LO1–LO3); ties to system power ground
HIN1–HIN3	High-side input signals	3.3V-compatible PWM inputs controlling HO1–HO3; in-phase response distinguishes IR21362J
LIN1–LIN3	Low-side input signals	Inverted relative to LO outputs; enables complementary drive without external inverters
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 source terminals	Return nodes for HO1–HO3; tolerate −5 V to +600 V offset vs. COM
VB1–VB3	Bootstrap supply inputs	Connect to bootstrap capacitors; supply high-side driver stages during HS conduction
ITRIP	Over-current sense input	Monitors shunt voltage; triggers simultaneous shutdown of all six outputs when threshold exceeded
RCIN	Fault clear timing input	RC network here sets auto-reset delay (1.3–2 ms typ.) after over-current or UVLO event
EN	Global enable input	Active-high signal that disables all outputs when low; provides hardware emergency stop
FAULT	Open-drain fault indicator	Pulls low during UVLO or over-current; requires external pull-up for system-level fault signaling

Key Features

Feature	Design Value
In-phase high-side logic	Eliminates need for external inverters on HIN lines, reducing BOM count and layout complexity in 3-phase PWM designs
Matched propagation delay	≤70 ns max mismatch across all six channels ensures synchronized switching and minimizes phase skew in motor commutation
Programmable fault clear	RCIN pin accepts external R-C network to set auto-recovery time (1.3–2 ms), enabling soft-fault handling without MCU intervention
Cross-conduction prevention	Dedicated dead-time insertion (220–360 ns) per channel prevents shoot-through during switching transitions
−5 V to +600 V VS tolerance	Supports operation under severe negative transients and full 600 V bus applications without external clamping

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
IR2136J	Higher V_CC/V_BS UVLO (8.9 V/8.2 V); out-of-phase HIN-to-HO logic; 10–20 V supply range	Requires external inverters for HIN signals; better suited for legacy 5 V logic systems	Select when interfacing with older 5 V microcontrollers and lower bus voltages (<400 V)
IR21363J	12–20 V V_CC/V_BS range; same in-phase logic as IR21362J; tighter UVLO hysteresis (0.2 V)	Improved noise margin on supply rails; identical pinout and feature set except for UVLO thresholds	Prefer for new designs targeting higher reliability in noisy industrial environments with fluctuating supplies

Compared with IR2136J and IR21363J, the IR21362J offers optimal balance of 3.3 V logic compatibility, moderate UVLO thresholds (10.4 V/9.4 V), and in-phase drive - making it ideal for cost-sensitive, space-constrained motor drives where bootstrap stability and MCU interface simplicity are prioritized.

FAQ

What is the purpose of the RCIN pin on the IR21362J?

The RCIN pin sets the automatic fault-clear delay time using an external resistor-capacitor network. When an over-current or undervoltage fault occurs, the FAULT pin goes low and remains asserted until the RCIN voltage exceeds 8 V, triggering recovery after 1.3–2 ms. This eliminates the need for MCU polling or external reset circuitry in transient-fault scenarios.

How does the IR21362J prevent shoot-through in a 3-phase bridge?

The IR21362J embeds dedicated dead-time insertion logic (220–360 ns) between complementary HIN/LIN inputs and HO/LO outputs per channel. It also enforces cross-conduction prevention by ensuring LO and HO outputs cannot be simultaneously active, even if input timing violates dead-time margins - a hardware-level safeguard against destructive shoot-through currents.

Can the IR21362J drive both MOSFETs and IGBTs?

Yes - the IR21362J is specified to drive both N-channel power MOSFETs and IGBTs. Its 200 mA source / 350 mA sink peak output current, 125 ns rise time, and 50 ns fall time meet gate drive requirements for devices up to ~100 A/600 V. The 3.3 V logic interface and in-phase HIN-to-HO mapping simplify integration with modern gate drivers in either technology.

What is the significance of "in-phase" high-side outputs in the IR21362J?

In-phase means HO1–HO3 follow HIN1–HIN3 directly (no inversion), unlike IR2136/IR21363 which invert HIN. This eliminates external inverters in PWM-driven systems, reduces gate loop inductance, improves timing predictability, and simplifies firmware design - especially valuable in FOC-based motor control where HIN timing directly maps to rotor position.
