Obsolete — sourcing options for the IRS24531DSPBF full-bridge driver
The Infineon IRS24531DSPBF is a single-channel gate driver configured for full-bridge (H-bridge) drive of N-Channel MOSFETs, with a 600 V bootstrap rating for the high-side floating supply.
Parametric fit for motor-drive and power-conversion designs
Supply voltage spans 10 V to 15.6 V, with logic-low threshold at 4.7 V and logic-high at 9.3 V — the bias rail must be at least 10 V to guarantee a valid logic-high input. Operating temperature range is -25°C to 125°C junction, covering industrial environments such as motor drives, uninterruptible power supplies, and off-line power converters. The 14-SOIC package (0.154 inch width) is a standard surface-mount footprint for automated assembly.
The IRS24531DSPBF is listed with a lifecycle stage of current but a product status of Obsolete. For a BOM requiring this specific driver, the independent distribution channel is the practical sourcing route — quoted to order per RFQ, with date-code and lot traceability confirmed at the time of quotation.
