It integrates a bootstrap diode for the high-side supply, rated to 600 V, which lets it directly drive the top device in a half-bridge leg without an isolated bias rail. The non-inverting input logic simplifies interface to a PWM controller or MCU. ## Output drive and switching speed Peak output current is 1.9 A source and 2.3 A sink, which is enough to charge and discharge the gate capacitance of medium-power IGBTs and MOSFETs in the 10–50 A range. ## Supply and logic thresholds The supply voltage range is 10 V to 20 V, matching standard gate drive bias rails for industrial and automotive power stages. It is supplied in a 14-SOIC (0.154-inch width) surface-mount package, which fits standard reflow assembly and keeps board area small. No official replacement or second-source part number is recorded in the available documentation. For new designs, consider the IR21844 (non-S suffix) or a newer Infineon half-bridge driver family such as the EiceDRIVER series — verify pin compatibility and parametric alignment against the BOM requirements.","metaTitle":"IR21844S Half-Bridge Gate Driver, 600V Bootstrap, 14-SOIC","metaDescription":"IR21844S half-bridge gate driver for IGBT/N-channel MOSFET. 600V bootstrap, 1.9A/2.3A peak output, 14-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tube","Gate Type":"IGBT, N-Channel MOSFET","Input Type":"Non-Inverting","Channel Type":"Synchronous","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"10V ~ 20V","Number of Drivers":"2","Base Product Number":"IR21844","Driven Configuration":"Half-Bridge","Operating Temperature":"-40°C ~ 150°C (TJ)","Rise / Fall Time (Typ)":"40ns, 20ns","Supplier Device Package":"14-SOIC","Logic Voltage - VIL, VIH":"0.8V, 2.7V","High Side Voltage - Max (Bootstrap)":"600 V","Current - Peak Output (Source, Sink)":"1.9A, 2.3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.9800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6fe00f96a8f216d35f11f4439898d52e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IR21844S/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between IR21844S and IR21844?","answer":"The IR21844S and IR21844 share the same base design (half-bridge, 600 V bootstrap, 1.9 A/2.3 A peak output).
