Infineon Technologies IR21364STRPBF

Overview

IR21364STRPBF from Infineon Technologies (formerly International Rectifier) is a high-voltage, high-speed 3-phase bridge driver IC with six independent gate drive channels (three high-side and three low-side), rated for 600 V offset voltage, 200 mA/350 mA peak output current, 500 ns/530 ns typical propagation delay, and 3.3 V logic compatibility. It integrates cross-conduction prevention logic, matched propagation delays, undervoltage lockout per channel, and programmable overcurrent fault clear via RCIN.

For engineers reviewing the IR21364STRPBF datasheet, IR21364STRPBF pinout, IR21364STRPBF application, or IR21364STRPBF equivalent, key selection considerations include bootstrap-compatible floating channel operation up to 600 V, independent half-bridge control for motor inverter stages, externally adjustable fault recovery timing, and industrial-grade qualification per JEDEC JESD47.

Technical Context

The IR21364STRPBF implements three isolated high-side drivers using proprietary HVIC technology, enabling direct N-channel MOSFET/IGBT control in topologies where VS swings up to 600 V relative to COM. Each high-side channel features dedicated VB/VS pins and internal level-shifting, while low-side outputs reference VSS/COM.

It embeds analog overcurrent detection via ITRIP input (0.37–0.55 V threshold), automatic fault latching with open-drain FAULT output, and RCIN-programmable clear delay (1.3–2 ms). Propagation delay matching ≤75 ns across all six channels ensures synchronized switching critical for high-frequency 3-phase PWM inverters.

FAQ

What is the maximum allowable dV/dt at the VS pins?

The IR21364STRPBF is rated for 50 V/ns dV/dt immunity on its high-side floating channels. This specification ensures reliable operation during fast-switching transients in 600 V IGBT-based inverters, preventing false triggering due to capacitive coupling between phase legs.

How does the RCIN pin determine fault clear timing?

The RCIN pin senses an external RC network (R = 2 MΩ, C = 1 nF typical) to set the FAULT clear delay (t_FLTCLR). When ITRIP deactivates, the internal timer waits until RCIN voltage drops below 5 V, then releases FAULT. The delay approximates R × C, ranging from 1.3 to 2 ms depending on component tolerance.

Can the EN pin override an active ITRIP fault?

No. The EN pin disables all outputs regardless of fault state, but it does not clear the FAULT signal or reset the ITRIP latch. FAULT remains asserted until the RCIN timeout completes, even if EN is toggled. This ensures fault persistence for system-level diagnostics before safe restart.

Is the IR21364STRPBF compatible with both MOSFETs and IGBTs?

Yes. Its 200 mA/350 mA peak output current, 11.5–20 V gate drive range, and 600 V offset rating support standard 600 V N-channel MOSFETs and IGBTs. The low-side output can sink 350 mA, sufficient for typical IGBT gate charge requirements up to 100 nC at 20 kHz.
