It drives the high-side and low-side FETs in a buck converter, with the high-side bootstrapped up to 33 V maximum — enough headroom for a 12 V input bus plus margin. Two drivers on-chip, non-inverting input logic. The 4 V to 6.85 V supply range ties it to a 5 V bias rail common in intermediate bus architectures. ## Gate drive strength and switching speed Peak output current is 3 A source and 4.5 A sink — the asymmetric sink strength pulls the gate down faster than it charges, which helps hold the low-side FET off during the dead-time interval. Typical rise time is 17 ns, fall time 12 ns into the rated load. For a 10 nC gate charge (typical of a small TO-220 MOSFET), the 4.5 A sink discharges the gate in roughly 2.2 ns — fast enough to keep cross-conduction losses low in a 500 kHz to 1 MHz switching regulator. ## Package and thermal interface Supplied in an 8-WDFN with exposed pad, also designated as 8-WSON (4x4 mm). The 4x4 mm footprint fits tight layouts near the power stage.","metaTitle":"Texas Instruments LM27222SD/NOPB Half-Bridge Gate Driver","metaDescription":"Active-production half-bridge N-channel MOSFET driver from TI. 3A source / 4.5A sink peak output, 17ns rise/12ns fall typ, 4V-6.85V supply. 8-WSON package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Gate Type":"N-Channel MOSFET","Input Type":"Non-Inverting","Channel Type":"Synchronous","Mounting Type":"Surface Mount","Package / Case":"8-WDFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"4V ~ 6.85V","Number of Drivers":"2","Driven Configuration":"Half-Bridge","Operating Temperature":"-40°C ~ 125°C (TJ)","Rise / Fall Time (Typ)":"17ns, 12ns","Supplier Device Package":"8-WSON (4x4)","High Side Voltage - Max (Bootstrap)":"33 V","Current - Peak Output (Source, Sink)":"3A, 4.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.84","priceTiers":[{"qty":1,"price":"$2.84000","currency":"USD"},{"qty":10,"price":"$2.55300","currency":"USD"},{"qty":25,"price":"$2.41360","currency":"USD"},{"qty":100,"price":"$2.09180","currency":"USD"},{"qty":250,"price":"$1.98452","currency":"USD"},{"qty":500,"price":"$1.78072","currency":"USD"},{"qty":1000,"price":"$1.51800","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7699cd936472a99654f7f0afdd8f2ce2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM27222SD%2FNOPB/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM27222SD-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM27222SD-NOPB when reusing this data.
