Product details
Overview
IR21365SPBF 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 VS offset, features 12–20V VCC/VBS supply range, 4.3V ITRIP threshold, matched 400ns/380ns turn-on/turn-off propagation delays, and integrated cross-conduction prevention logic-used in industrial motor inverters and servo drives.
For engineers reviewing the IR21365SPBF datasheet, IR21365SPBF pinout, IR21365SPBF application, or IR21365SPBF equivalent, key selection criteria include its 600V floating channel capability, programmable fault-clear delay via RCIN, 3.3V logic compatibility, undervoltage lockout thresholds (11.2V/11.0V), and automatic over-current shutdown behavior across all six outputs.
Technical Context
The IR21365SPBF integrates three independent HVIC-based floating channels with level-shifted inputs and shoot-through prevention logic that enforces deadtime between HOx and LOx outputs per phase. Its internal UVLO monitors both VCC and VBx supplies independently with 0.2V hysteresis and latched fault response.
It implements a dominant-latch FAULT circuit triggered by either ITRIP > 4.3V or VCC/VBx falling below UV thresholds; fault recovery requires RCIN voltage to exceed 8V, enabling externally adjustable clear timing (1.3–2 ms typical). Input noise filters on HIN/LIN/EN provide 100–200 ns rejection window.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VS Max | +600 V - supports high-side switching in 400–600V DC bus motor drives |
| VCC/VBS Range | 12–20 V - enables use with standard 15V gate drive rails and bootstrap diode designs |
| ITRIP Threshold | 4.3 V (typ.) - sets current-sense comparator trip point for over-current protection |
| tON/tOFF | 400 ns / 380 ns (typ.) - ensures precise PWM timing alignment across all 3 phases |
| UVLO Thresholds | 11.2 V (rising), 11.0 V (falling) - prevents erratic operation during brown-out conditions |
| Logic Compatibility | 3.3 V CMOS/LSTTL - interfaces directly with modern microcontrollers without level shifters |
| Fault Clear Delay | Programmable via RCIN (1.3–2 ms typical) - allows configurable restart timing after over-current event |
Pinout & Package
IR21365SPBF is available in 28-lead SOIC package with exposed pad for thermal enhancement. Pin assignments are validated per Infineon PD60166 revS datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Low-side and logic supply input | Provides power to internal logic and low-side drivers; must be ≥12 V for reliable operation |
| VSS | Logic ground reference | Common return for all logic inputs and internal bias circuits; separate from COM |
| COM | Power ground reference | Return path for low-side outputs (LO1–LO3); tied to system power ground |
| HIN1–HIN3 | High-side input control | Inverted logic input (active-high signal produces active-low HO output) |
| LIN1–LIN3 | Low-side input control | Inverted logic input (active-high signal produces active-low LO output) |
| HO1–HO3 | High-side gate drive outputs | Floating outputs referenced to VS1–VS3; drive external N-channel devices in high-side configuration |
| LO1–LO3 | Low-side gate drive outputs | Ground-referenced outputs; sink/source capability supports fast MOSFET switching |
| VS1–VS3 | High-side floating supply return | Source node of high-side power device; defines local ground for corresponding HOx output |
| VB1–VB3 | High-side floating supply input | Bootstrap or isolated supply input for high-side driver stage; must exceed VSx by ≥12 V |
| ITRIP | Over-current sense input | Analog input monitoring shunt voltage; triggers shutdown when ≥4.3 V |
| RCIN | Fault clear timing input | RC network connection point; controls automatic fault recovery delay (1.3–2 ms typical) |
| EN | Global enable/disable input | Active-high input; forces all outputs low when pulled low |
| FAULT | Open-drain fault indicator | Drains to VSS when UV or over-current condition occurs; requires external pull-up |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel architecture | Enables direct driving of high-side N-MOSFETs/IGBTs up to +600V VS offset without external level shifters |
| Matched propagation delay | ≤70 ns max mismatch across all six outputs ensures synchronized PWM timing in 3-phase systems |
| Cross-conduction prevention logic | Hardware-enforced deadtime (220–360 ns) eliminates shoot-through risk during switching transitions |
| Externally programmable fault clear | RCIN pin accepts R-C network to set precise auto-restart delay after over-current events |
| 3.3V logic interface | Direct compatibility with ARM Cortex-M, DSP, and FPGA GPIO without level translation circuitry |

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 |
|---|---|---|---|
| IR21363SPBF | Same package and pinout; lower 0.46V ITRIP threshold and 11.2V/11.0V UVLO | Better suited for low-current sensing (<1A shunt) and tighter UV margins | Select when using small-value current sense resistors and stable 15V supplies |
| IR21367SPBF | Same ITRIP (4.3V) and UVLO but faster 250ns/180ns propagation delays | Optimized for >50 kHz switching frequencies and reduced timing skew | Choose for high-frequency SiC or GaN-based inverters requiring sub-200ns tOFF |
Compared with IR21363SPBF and IR21367SPBF, the IR21365SPBF balances robust over-current detection (4.3V ITRIP), moderate propagation speed (400ns/380ns), and wide 12–20V supply tolerance-making it ideal for general-purpose industrial motor drives where cost, reliability, and design simplicity are prioritized over ultra-high frequency operation.

FAQ
What is the maximum allowable dV/dt at the VS pins?
The IR21365SPBF is rated for −50 V/ns dV/dt immunity on VS1–VS3 pins, verified under test conditions per PD60166 revS. This specification ensures stable operation during fast-switching transients in IGBT-based inverters without false triggering of level-shifted channels.
Can the FAULT pin be used to trigger a microcontroller interrupt?
Yes-the FAULT pin is an open-drain output with 50–100 Ω on-resistance, compatible with 3.3V or 5V MCU interrupt inputs when paired with a 4.7kΩ pull-up resistor. Its assertion time is ≤800 ns after ITRIP exceeds 4.3V, enabling real-time fault capture.
Is bootstrap capacitor sizing different for IR21365SPBF versus IR21362?
Yes-due to its 12–20V VBS range and higher quiescent current (120 µA typical), IR21365SPBF requires ≥0.22 µF ceramic bootstrap capacitors per channel at 20 kHz PWM, whereas IR21362's 11.5–20V range allows slightly smaller values under identical conditions.
Does the EN pin override the FAULT condition?
No-the EN pin disables all outputs regardless of FAULT status, but does not clear the FAULT latch. Once asserted, FAULT remains active until RCIN voltage exceeds 8V, even if EN is re-enabled; this ensures fault persistence across enable cycles.
