Infineon Technologies IR25600PBF

Overview

IR25600PBF from International Rectifier is a dual low-side gate driver IC for power MOSFETs and IGBTs, featuring matched 85 ns / 65 ns turn-on/turn-off propagation delays, ±1.5 A peak output current per channel, and 6–20 V gate drive supply range in an 8-lead PDIP package. It enables synchronous half-bridge or dual-switch topologies in motor drives and DC-DC converters.

For engineers reviewing the IR25600PBF datasheet, IR25600PBF pinout, IR25600PBF application, or IR25600PBF equivalent, key selection criteria include input logic compatibility (CMOS/LSTTL), latch-immune CMOS process, matched inter-channel delay, high-current pulsed output capability, and thermal performance under continuous operation at 125°C ambient.

Technical Context

The IR25600PBF integrates two independent low-side drivers with Schmitt-triggered CMOS inputs and high-current buffer stages to minimize cross-conduction during switching transitions. Its proprietary latch-immune process ensures robustness against noise-induced false triggering in high-dV/dt environments.

Each channel delivers 1.5 A typical peak source/sink current into capacitive loads, with propagation delays tightly matched (≤20 ns skew) between IN→OUTA and IN→OUTB paths. The device operates across full industrial temperature range (−40°C to +125°C) with fixed VS supply referenced to GND.

FAQ

What is the maximum allowable gate capacitance this driver can switch within its specified timing?

The IR25600PBF delivers ±1.5 A peak current with 15 ns rise time and 10 ns fall time into 1000 pF loads. For a 10 nF gate capacitance, it achieves ~100 ns total switching time (Qg/Ipeak), staying within practical limits for 100 kHz operation. Larger capacitances require derating switching frequency or verifying thermal margin.

Can the IR25600PBF drive IGBTs directly without external components?

Yes-the IR25600PBF is explicitly rated for IGBT gate drive, with ±1.5 A peak output current and 6–20 V supply range matching standard IGBT gate requirements. No external boost transistors or level shifters are needed for typical 600 V/1200 V IGBTs with Qg ≤ 100 nC.

Why does the datasheet specify two different propagation delay values (ton = 85 ns, toff = 65 ns)?

This asymmetry reflects inherent differences in internal pull-up vs. pull-down transistor sizing optimized for fast turn-off and controlled turn-on. It is intentional design behavior-not a mismatch-and matches typical MOSFET/IGBT gate charge profiles where faster discharge reduces shoot-through risk during switching transitions.

Are pins 6 and 7 truly no-connect, or do they serve a thermal or mechanical function?

Pins 6 and 7 are confirmed no-connect (NC) terminals with no internal bonding or electrical connection. They serve only mechanical reinforcement in the PDIP8 package and must remain unconnected in PCB layout. No thermal benefit is provided; thermal performance relies solely on GND and VS lead thermal paths.
