It integrates a bootstrap diode rated for a high-side voltage of 600 V, letting it float the top gate drive above a DC bus rail in motor drives, UPS inverters, and switch-mode power supplies. The non-inverting input simplifies control logic — a single PWM signal from a controller or MCU drives both the high-side and low-side outputs with built-in dead-time to prevent shoot-through. The 210 mA source and 360 mA sink peak output current is sized for medium-power IGBT modules and MOSFETs with gate charge up to roughly 100 nC at moderate switching frequencies. ## Supply range and thermal envelope The supply range is 10 V to 20 V. The junction temperature rating is -40°C to 150°C. The 100 ns typical rise and 50 ns fall time keep switching losses low in the 20–100 kHz range typical for motor-drive PWM. The IR2104S shares the same base product number (IR2104) as the through-hole IR2104, but the 'S' suffix denotes the SOIC-8 surface-mount package — not a functional difference.","metaTitle":"IR2104S Half-Bridge Gate Driver, 600 V Bootstrap, 210/360 mA","metaDescription":"IR2104S half-bridge gate driver for IGBT/N-channel MOSFET. 600 V bootstrap, 210/360 mA peak drive, 10-20 V supply, -40 to 150°C.","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":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"10V ~ 20V","Number of Drivers":"2","Base Product Number":"IR2104","Driven Configuration":"Half-Bridge","Operating Temperature":"-40°C ~ 150°C (TJ)","Rise / Fall Time (Typ)":"100ns, 50ns","Supplier Device Package":"8-SOIC","Logic Voltage - VIL, VIH":"0.8V, 3V","High Side Voltage - Max (Bootstrap)":"600 V","Current - Peak Output (Source, Sink)":"210mA, 360mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/55cdba86a12abe951302711c1ca721e2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IR2104S/alternatives.json"},"ai":{"faq":[{"question":"Is the IR2104S obsolete?","answer":"Yes, the IR2104S is listed as Obsolete.
