Infineon Technologies IRS2001PBF-INF

Overview

IRS2001PBF-INF from Infineon Technologies is a high-voltage, dual-channel gate driver IC for N-channel MOSFETs and IGBTs, featuring independent high-side (HO) and low-side (LO) outputs with 200 V offset capability, 200 mA/420 mA peak output current, 160 ns/150 ns typical propagation delay, and 3.3 V–15 V logic-compatible inputs. It enables half-bridge switching in motor drives and inverters.

For engineers reviewing the IRS2001PBF-INF datasheet, IRS2001PBF-INF pinout, IRS2001PBF-INF application, or IRS2001PBF-INF equivalent, key selection criteria include floating channel dV/dt immunity, matched propagation delay (<50 ns), undervoltage lockout thresholds (8.2–9.8 V on VCC), and SOIC-8 package thermal resistance (200 °C/W).

Technical Context

The IRS2001PBF-INF integrates a latch-immune HVIC process enabling robust high-side operation up to +200 V VS offset, with bootstrap-compatible VB supply and COM-referenced logic interface. Its dual-channel architecture delivers in-phase HO and LO outputs synchronized to HIN/LIN inputs.

Propagation delays are tightly matched (≤50 ns max difference between channels), and dynamic performance is specified across temperature (−40°C to +125°C) and supply voltage (10–20 V), supporting reliable timing-critical bridge control in variable-speed drives.

Key Specifications

Pinout & Package

IRS2001PBF-INF is housed in an 8-lead SOIC package (RoHS-compliant, Pb-free), with exposed pad not electrically connected. The package supports surface-mount reflow and meets JEDEC MS-012 standards.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage half-bridge gate driver applications.

Compared with IRS2001PBF-INF, IRS2104SPbF lacks matched delay and integrated UVLO, limiting use in synchronous bridge control, while UCC27211D offers higher drive current but sacrifices 3.3 V logic compatibility and adds board-level complexity.

FAQ

What is the maximum allowable dV/dt on the VS pin?

The IRS2001PBF-INF is rated for 50 V/ns dV/dt on the VS pin under all operating conditions. This specification is validated per test condition in the datasheet and ensures reliable operation without false triggering during fast-switching events in half-bridge configurations, such as those found in BLDC motor drives and inverters.

Can IRS2001PBF-INF drive SiC MOSFETs?

Yes - its 200 mA/420 mA peak output current, 160 ns/150 ns propagation delays, and 50 V/ns dV/dt immunity make it suitable for driving low-to-mid capacitance SiC MOSFETs (e.g., 1200 V/40 mΩ types) in microinverters and EV chargers, provided gate resistors are selected to limit dv/dt within device limits.

Is an external bootstrap diode required?

Yes - the IRS2001PBF-INF requires an external fast-recovery bootstrap diode (e.g., 1N4148WS or equivalent) between VCC and VB to charge the high-side floating supply capacitor. The IC does not integrate this diode, and omission will prevent high-side output functionality.

Does IRS2001PBF-INF support 3.3 V logic directly?

Yes - the HIN and LIN inputs are fully compatible with 3.3 V CMOS logic levels, with VIH(min) = 2.5 V and VIL(max) = 0.8 V at 25°C. No level-shifting circuitry is needed when interfacing with 3.3 V microcontrollers or FPGAs, simplifying PCB layout and reducing BOM count.
