The driver operates from a 3.7V to 20V supply rail, covering bias voltages from secondary-side regulated rails up to a 20V bootstrap supply. Logic input thresholds are set at 0.7V for VIL and 2.6V for VIH, compatible with 3.3V and 5V PWM controllers. The inverting input polarity means a logic high on the input turns the corresponding output low — confirm the controller's output polarity in the BOM review. ## Obsolete — sourcing via independent channel Expect to qualify date-code and condition on any available stock.","metaTitle":"UCC27221PWPG4 Half-Bridge MOSFET Driver, 4A Peak, Obsolete","metaDescription":"Texas Instruments UCC27221PWPG4 half-bridge N-channel MOSFET driver, 4A peak output, 3.7V–20V supply, 14-HTSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tube","Gate Type":"N-Channel MOSFET","Input Type":"Inverting","Channel Type":"Synchronous","Mounting Type":"Surface Mount","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width) Exposed Pad","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"3.7V ~ 20V","Number of Drivers":"2","Base Product Number":"UCC272","Driven Configuration":"Half-Bridge","Operating Temperature":"-55°C~115°C(TJ)","Rise / Fall Time (Typ)":"17ns, 17ns","Supplier Device Package":"14-HTSSOP","Logic Voltage - VIL, VIH":"0.7V, 2.6V","Current - Peak Output (Source, Sink)":"4A, 4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/055c04298fa776d84131f556ccf4d545.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/UCC27221PWPG4/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/UCC27221PWPG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/UCC27221PWPG4 when reusing this data.
