Product details
Overview
IR21366SPBF 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 supports up to +600V floating operation, features 250ns/180ns typical turn-on/turn-off propagation delays, 3.3V logic compatibility, and programmable fault-clear delay via RCIN. It is used in motor inverters for HVAC compressors and industrial servo drives.
For engineers reviewing the IR21366SPBF datasheet, IR21366SPBF pinout, IR21366SPBF application, or IR21366SPBF equivalent, key selection criteria include its 12–20V VCC/VBS supply range, matched channel delays (≤70ns max mismatch), integrated shoot-through prevention, and external current-sense trip threshold of 0.46V.
Technical Context
The IR21366SPBF integrates three isolated high-side and low-side drivers using proprietary HVIC technology, enabling robust monolithic construction for 600V-rated systems. Its floating channels use level-shifted logic with dV/dt immunity, and each channel includes matched propagation delay (±40ns) and built-in dead-time generation (220–360ns).
It implements over-current shutdown via an external sense resistor connected to ITRIP, with automatic fault recovery timed by an RC network on RCIN. The FAULT pin is open-drain and asserts during UVLO (VCC/VBS <11.0V) or over-current events, while EN provides synchronous global disable of all six outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC/VBS Supply Range | 12–20V - ensures stable gate drive for 12V–15V bootstrap supplies in 3-phase inverter stages |
| Propagation Delay (ton/toff) | 250ns / 180ns typ. - enables >1MHz PWM switching with precise timing control across all 3 phases |
| Logic Input Thresholds | VIH = 2.0V, VIL = 1.3V - guarantees reliable 3.3V CMOS/LSTTL interface without level-shifting |
| ITRIP Threshold | 0.46V typ. - sets over-current trip point for shunt-based current sensing with minimal gain error |
| UVLO Thresholds | VCCUV+ = 11.2V, VCCUV− = 11.0V - prevents erratic operation during brown-out conditions in high-noise motor drive environments |
| VS Offset Rating | −5V to +600V - supports high-side switching in 400VDC bus applications like PMSM inverters |
| Output Drive Current | IO+ = 200mA, IO− = 350mA - delivers sufficient peak current to charge/discharge 1000pF gate loads within 125ns rise time |
Pinout & Package
IR21366SPBF is housed in a 28-lead SOIC package with exposed thermal pad (SOIC-28W), optimized for thermal dissipation in motor control PCB layouts. Pin assignments are validated per Infineon PD60166 revS datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Low-side and logic supply input | Provides 12–20V power for internal logic and low-side drivers; referenced to VSS |
| VSS | Logic ground reference | Common return for logic inputs (HIN/LIN/EN/ITRIP/RCIN); must be tied to system digital ground |
| COM | Power ground reference | Return path for low-side outputs (LO1–LO3); connects to inverter leg source nodes |
| HIN1–HIN3 | High-side input signals | Inverted logic inputs controlling HO1–HO3; compatible with 3.3V microcontroller PWM outputs |
| LIN1–LIN3 | Low-side input signals | Inverted logic inputs controlling LO1–LO3; synchronized with HIN for complementary drive |
| HO1–HO3 | High-side gate drive outputs | Floating outputs referenced to VS1–VS3; drive N-MOSFET gates in high-side configuration |
| LO1–LO3 | Low-side gate drive outputs | Ground-referenced outputs driving N-MOSFET gates at inverter leg sources |
| VS1–VS3 | High-side floating supply return | Connects to source of high-side switch; defines local ground for corresponding HO output |
| VB1–VB3 | High-side floating supply input | Accepts bootstrap voltage (VSx + 12–20V) to power respective high-side driver stage |
| FAULT | Open-drain fault indicator | Asserts low during UVLO or over-current; requires external pull-up for system-level fault signaling |
| ITRIP | Over-current sense input | Monitors voltage across external shunt; trips all outputs when ≥0.46V (typ.) |
| RCIN | Programmable fault-clear timing input | RC network here sets auto-clear delay (1.3–2ms); threshold is 8V with 3V hysteresis |
| EN | Global enable/disable input | Active-high; forces all six outputs low when deasserted, overriding individual HIN/LIN states |
Key Features
| Feature | Design Value |
|---|---|
| Matched propagation delay across all six channels | ≤70ns max difference ensures synchronized switching in 3-phase PMSM/BLDC inverters |
| Cross-conduction prevention logic | Hardware-enforced dead-time (220–360ns) eliminates shoot-through risk without firmware dependency |
| Externally programmable fault-clear delay | RCIN pin accepts R-C network (e.g., 2MΩ + 1nF) to set 1.3–2ms auto-recovery window after over-current |
| −5V to +600V VS offset tolerance | Supports high dv/dt transients in 400VDC bus systems without false triggering or latch-up |
| 3.3V logic-compatible inputs with low bias current | Input leakage ≤1µA at HIN/LIN enables direct connection to low-power MCU GPIOs |

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 |
|---|---|---|---|
| IR21367SPBF | Same 12–20V supply and 0.46V ITRIP threshold, but uses 4.3V ITRIP option in alternate variants; identical timing specs | Designed for systems where higher noise immunity on ITRIP line is required via 4.3V threshold | Select IR21367SPBF only if design requires higher trip threshold to reject transient noise on current sense path |
| IRS2336MTRPBF | Lower 10–20V VCC range, 350ns/250ns propagation delays, no RCIN programmability; integrated bootstrap diode | Suitable for cost-sensitive, lower-frequency (<10kHz) inverters where auto-fault-clear is not required | Choose IRS2336MTRPBF for simplified layout (integrated diode) and reduced BOM count where timing precision is secondary |
Compared with IR21367SPBF and IRS2336MTRPBF, the IR21366SPBF offers the fastest switching timing (250ns/180ns), precise 0.46V current-sense threshold, and field-configurable fault recovery-making it optimal for high-efficiency, high-bandwidth motor control where timing accuracy and noise-immune protection are critical.

FAQ
What is the maximum allowable dV/dt at the VS pins for IR21366SPBF?
The IR21366SPBF is rated for up to 50 V/ns dV/dt at VS pins under normal operating conditions. This specification ensures reliable level-shifting operation during fast-switching events in 600V-class inverters without false triggering or latch-up, as verified in Infineon's characterization tests per PD60166 revS.
Can IR21366SPBF drive both MOSFETs and IGBTs?
Yes, the IR21366SPBF is designed to drive both N-channel power MOSFETs and IGBTs in high-side and low-side configurations. Its 200mA/350mA peak output current and 12–20V gate drive supply range meet typical gate charge requirements for devices up to 50A/600V, as confirmed in Infineon's application notes AN-978 and DT97-3.
How does the RCIN pin determine fault-clear timing?
The RCIN pin sets fault-clear delay by charging an external capacitor through a resistor; the internal comparator triggers clear when RCIN voltage exceeds 8V (with 3V hysteresis). With R=2MΩ and C=1nF, timing is 1.3–2ms, as specified in the Dynamic Electrical Characteristics table of PD60166 revS.
Is there a recommended minimum pulse width for HIN inputs?
Yes, the datasheet specifies a minimum HIN pulse width of 1µs for reliable high-side PWM operation. This ensures sufficient time for internal level-shifting and latch settling, especially under worst-case temperature and supply conditions, as defined in the "Dynamic Electrical Characteristics" section of PD60166 revS.
