Product details
Overview
IR21362STR 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 high-side floating channels, features 3.3V logic compatibility, in-phase high-side output polarity, and programmable fault-clear delay via RCIN. Used in motor inverters for HVAC compressors and industrial AC drives.
For engineers reviewing the IR21362STR datasheet, IR21362STR pinout, IR21362STR application, or IR21362STR equivalent, key selection criteria include its 11.5–20V VCC supply range, matched 400ns/380ns turn-on/turn-off propagation delays, UVLO thresholds at 10.4V (rising) and 9.4V (falling), and integrated cross-conduction prevention logic for reliable 3-phase PWM control.
Technical Context
The IR21362STR implements proprietary HVIC technology for monolithic high-voltage isolation between logic and power domains. Its floating channel architecture supports bootstrap gate drive for high-side switches operating with VS offset up to 600V referenced to COM, while maintaining dV/dt immunity up to 50 V/ns.
It integrates independent dead-time generation and shoot-through prevention logic per channel, with in-phase high-side output behavior distinguishing it from IR2136/IR21363 variants. Fault management includes open-drain FAULT signaling and externally programmable auto-clear timing via RCIN (1.3–2 ms typical with R=2 MΩ, C=1 nF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply Range | 11.5 V to 20 V - sets minimum gate drive voltage headroom for low-side and logic circuits |
| High-Side Offset Voltage | Up to +600 V - enables direct driving of high-side N-MOSFETs/IGBTs in 3-phase bridge topologies |
| Propagation Delay (ton/toff) | 400 ns / 380 ns typ - ensures precise timing alignment across all six outputs for high-frequency PWM (≥100 kHz) |
| UVLO Thresholds | 10.4 V (rising), 9.4 V (falling) - prevents erratic switching during brown-out conditions with 1.0 V hysteresis |
| Logic Compatibility | 3.3 V CMOS/LSTTL - allows direct interfacing with modern microcontrollers without level-shifting |
| ITRIP Threshold | 0.46 V typ - enables accurate overcurrent detection using low-value, low-power sense resistors (e.g., 5–20 mΩ) |
| RCIN Fault-Clear Time | 1.3–2.0 ms - provides adjustable recovery window after overcurrent event before automatic reset |
Pinout & Package
IR21362STR is housed in a 28-lead SOIC package with exposed thermal pad (RoHS-compliant, lead-free). Pin assignments are validated per Infineon PD60166 revS datasheet and match industry-standard 3-phase driver layout conventions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Low-side and logic supply input | Provides regulated 11.5–20 V power for internal logic and low-side drivers |
| VSS | Logic ground reference | Common return for all digital inputs and internal bias networks |
| COM | Power ground reference | Return path for low-side outputs LO1–LO3 and current-sense circuitry |

| HO1–HO3 | High-side gate drive outputs | Floating outputs referenced to VS1–VS3; drive bootstrap-fed high-side gates |
| LO1–LO3 | Low-side gate drive outputs | Ground-referenced outputs capable of 200 mA sink / 120 mA source peak current |
| VS1–VS3 | High-side floating supply returns | Source nodes of high-side power devices; define local ground for each HV channel |
| VB1–VB3 | High-side floating supply inputs | Accept bootstrap capacitor voltage (VSx + 11.5–20 V) to power high-side drivers |
| ITRIP | Overcurrent sense input | Analog input monitoring external shunt; triggers shutdown when >0.46 V |
| RCIN | Fault clear timing input | RC network connection point setting auto-reset delay after overcurrent event |
| EN | Global enable input | Active-high signal disabling all six outputs simultaneously when pulled low |
| FAULT | Open-drain fault indicator | Signals UVLO or overcurrent condition; requires external pull-up to VCC |
Key Features

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 |
|---|---|---|---|
| IR2136STR | Out-of-phase high-side outputs; lower VCC UVLO (8.9 V rising); 10–20 V VCC range | Requires inverted HIN signals from controller; less suitable for 3.3 V logic-only systems | Select when legacy controller outputs are already inverted or when lower UVLO threshold is acceptable |
| IR21363STR | Out-of-phase high-side outputs; higher VCC UVLO (11.1 V rising); 12–20 V VCC range | Better noise margin in high-voltage industrial settings but incompatible with in-phase control schemes | Prefer for new designs needing tighter UVLO margin and higher supply stability at cost of logic inversion |
Compared with IR2136STR and IR21363STR, the IR21362STR uniquely supports in-phase high-side control-reducing firmware complexity and eliminating external inverters-while offering mid-range UVLO thresholds ideal for 12–15 V auxiliary supplies in motor drives.

FAQ
What is the maximum allowable dV/dt on the VS pins?
The IR21362STR is rated for dV/dt immunity up to 50 V/ns on VS1–VS3 pins, verified under standard test conditions per PD60166 revS. This specification ensures reliable operation during fast-switching events in hard-switched inverters without false triggering of level-shifters or latch-up.
Can the FAULT pin drive an LED directly?
Yes-the FAULT pin is an open-drain output rated for 20 mA sink current. With a 1 kΩ pull-up to VCC (15 V), it can directly drive a standard 2 mA LED indicator. Ensure the LED forward voltage does not exceed VCC minus saturation voltage (typically <0.6 V at 20 mA).
Does the IR21362STR require external bootstrap diodes?
No-external bootstrap diodes are required. The device itself does not integrate them; standard ultrafast 1 A diodes (e.g., BAS21) must be placed between VBx and VSx to charge the bootstrap capacitors during low-side conduction periods.
How is dead time generated in the IR21362STR?
Dead time is generated internally by dedicated logic that enforces minimum off-time between complementary HOx and LOx transitions. Measured at 220–360 ns, it is fixed and non-programmable-designed to prevent shoot-through while allowing high-frequency operation without external timing components.
