It integrates a bootstrap diode for the high-side supply, allowing a single 10 V to 15.6 V bias rail to drive both the low-side and high-side gates. The RC input circuit sets the oscillator frequency and dead-time with external passive components, making it a self-oscillating driver suited for resonant and half-bridge converter topologies. ## Switching speed and high-voltage capability The 600 V maximum bootstrap voltage rating defines the DC bus voltage ceiling for offline supplies and DC bus applications with adequate derating.","metaTitle":"IR21531D Half-Bridge Gate Driver, 600 V Bootstrap, 80/45 ns","metaDescription":"IR21531D half-bridge N-channel MOSFET driver with 600 V bootstrap, 80 ns rise/45 ns fall, -40°C to 125°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":"N-Channel MOSFET","Input Type":"RC Input Circuit","Channel Type":"Synchronous","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"10V ~ 15.6V","Number of Drivers":"2","Base Product Number":"IR21531","Driven Configuration":"Half-Bridge","Operating Temperature":"-40°C~125°C(TJ)","Rise / Fall Time (Typ)":"80ns, 45ns","Supplier Device Package":"8-PDIP","Logic Voltage - VIL, VIH":"-","High Side Voltage - Max (Bootstrap)":"600 V","Current - Peak Output (Source, Sink)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9600","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IR21531D/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between IR21531 and IR21531D?","answer":"The 'D' suffix typically indicates a different package variant or minor electrical revision.
