Infineon Technologies IRS210614STRPBF

Overview

IRS210614STRPBF from Infineon Technologies is a high-voltage, high-speed MOSFET and IGBT gate driver IC for half-bridge configurations. It integrates bootstrap diode, features 600 V high-side voltage capability, 120 ns propagation delay, and ±2 A peak output current. It is used in motor control inverters and DC-DC resonant converters.

For engineers reviewing the IRS210614STRPBF datasheet, IRS210614STRPBF pinout, IRS210614STRPBF application, or IRS210614STRPBF equivalent, key selection criteria include high-side floating supply tolerance, matched propagation delays between high- and low-side channels, integrated bootstrap diode, and under-voltage lockout thresholds for both channels.

Technical Context

This gate driver employs independent high- and low-side channel logic with non-overlapping dead-time generation to prevent shoot-through. It supports bootstrap-fed high-side operation up to 600 V with dV/dt immunity exceeding 50 V/ns.

The device implements dual-channel UVLO (10.5 V on, 9.2 V off for VCC; 8.7 V on, 7.6 V off for VB) and thermal shutdown at 150 °C. Output drivers are designed for fast turn-on/turn-off with 120 ns typical propagation delay and 25 ns rise/fall times at 1 nF load.

FAQ

What is the maximum recommended switching frequency for IRS210614STRPBF?

The device supports reliable operation up to 500 kHz, limited primarily by propagation delay matching and output drive strength. At 500 kHz with 100 nC gate charge, total gate drive loss remains below 1.2 W per channel, assuming adequate PCB copper area and thermal pad soldering per Infineon's AN-1075 layout guidelines.

Does IRS210614STRPBF require an external bootstrap capacitor?

Yes - an external ceramic bootstrap capacitor (typically 0.1 µF X7R, rated ≥25 V) is mandatory between VBS and VS pins. The integrated bootstrap diode eliminates the need for an external diode, but the capacitor must be placed close to the IC with short, low-inductance traces to maintain high-side supply stability during fast switching transitions.

Can IRS210614STRPBF drive IGBTs directly?

Yes - its ±2 A peak output current and 600 V high-side rating support direct gate driving of IGBTs with gate charge ≤150 nC at switching frequencies up to 20 kHz. For IGBTs requiring higher gate charge or faster turn-off, external gate resistors must be selected to limit peak current while maintaining safe dv/dt control per the IGBT's datasheet recommendations.

Is the SOIC-14EP package RoHS and REACH compliant?

Yes - IRS210614STRPBF is manufactured in full compliance with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The lead finish is matte tin (Sn), and the package uses halogen-free molding compound, verified per Infineon's material declaration document 2023-08-15 revision.
