IR2104STRPBF

Gate Driver Overview

The IR2104STRPBF is a 600 V half-bridge gate driver IC designed for driving IGBTs and N-channel MOSFETs. It features two independent output channels with a source current of 0.21 A and a sink current of 0.36 A. The device operates within a VCC supply range of 10 V to 20 V, with UVLO thresholds at 8.9 V (On) and 8.2 V (Off). Propagation delays are specified as 680 ns for turn-on and 150 ns for turn-off. It utilizes junction isolation for the high-side level shift and includes a shutdown function. The component supports a maximum power dissipation of 625 mW and functions across an operating temperature range of -40°C to +125°C.

Gate Driver Procurement Notes

Verify that the ordering suffix STRPBF corresponds to the SOIC-8 surface-mount package and tape-and-reel delivery format. Confirm RoHS compliance status through official Infineon documentation or certified distributor declarations. Ensure the specific batch matches the required industrial quality grade. Cross-reference the datasheet version to validate electrical parameters against system requirements before finalizing procurement orders.

Gate Driver Selection Notes

Select this component when a 600 V rating and half-bridge configuration are required for IGBT or MOSFET applications. The 0.21 A source and 0.36 A sink currents support moderate gate charge loads. Consider the 10 V to 20 V supply range and the presence of a shutdown input for system safety logic. Verify that the SOIC-8 package fits the PCB layout constraints and thermal management strategy.
