That current capability handles the gate charge of large N-channel and P-channel MOSFETs in power converters, motor drives, and switch-mode supplies without a separate booster stage. ## 4 V to 15 V supply — wide bias compatibility The supply range from 4 V to 15 V lets the driver operate from standard 5 V, 12 V, or 15 V bias rails. ## Through-hole 8-PDIP — rework-friendly footprint The 8-PDIP package (0.300-inch body, 7.62 mm width) is a through-hole DIP that suits prototyping, low-volume builds, and applications where socketing or manual rework is preferred.","metaTitle":"UCC27321PE4 MOSFET Driver, 9A Peak, 8-PDIP, Last Buy","metaDescription":"Texas Instruments UCC27321PE4 single low-side MOSFET driver, 9A peak output, 4V-15V supply, inverting input, 8-PDIP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tube","Gate Type":"N-Channel, P-Channel MOSFET","Input Type":"Inverting","Channel Type":"Single","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Product Status":"Last Time Buy","lifecycle_stage":"eol_hot","Voltage - Supply":"4V ~ 15V","Number of Drivers":"1","Driven Configuration":"Low-Side","Operating Temperature":"-40°C ~ 105°C (TA)","Rise / Fall Time (Typ)":"20ns, 20ns","Supplier Device Package":"8-PDIP","Logic Voltage - VIL, VIH":"1V, 2V","Current - Peak Output (Source, Sink)":"9A, 9A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1479","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d93a5fd0a0ceecf9322c35ef8688cb00.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/UCC27321PE4/alternatives.json"},"ai":{"faq":[{"question":"Is UCC27321PE4 obsolete?","answer":"Texas Instruments lists the UCC27321PE4 as Last Buy, meaning it is in its final production phase.
