The inverting input logic means the driver output is the complement of the input signal — useful when the PWM controller output polarity needs flipping to match the high-side / low-side timing. ## What the 4A peak drive and 17ns edges mean for your switching stage A 4A peak gate drive and 17ns rise/fall time set the minimum dead-time needed to avoid cross-conduction. The synchronous channel type provides break-before-make timing internally. The 14-HTSSOP package with exposed pad pulls heat from the driver die into the PCB copper. The junction temperature rating is -55°C to 115°C. ## Obsolete — sourcing the UCC27221PWPR for existing BOM lines Because the base product number is UCC272, there may be other variants in the family (different package, temperature grade, or tape/reel option) that are still active. A cross-reference search against the full UCC272xx family is worthwhile if the board can accommodate a different package or temperature range.","metaTitle":"Texas Instruments UCC27221PWPR Half-Bridge Gate Driver","metaDescription":"Texas Instruments UCC27221PWPR half-bridge N-channel MOSFET driver. 4A peak source/sink, 17ns rise/fall, 3.7V-20V supply.","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":"Tape & Reel (TR)","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":"$2.1500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/055c04298fa776d84131f556ccf4d545.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/UCC27221PWPR/alternatives.json"},"ai":{"faq":[{"question":"What are the key electrical specifications of the UCC27221PWPR?","answer":"The input logic thresholds are 0.7V (VIL) and 2.6V (VIH).
