This drive strength handles the gate charge of large synchronous rectifier MOSFETs in high-current voltage regulator modules, keeping switching losses in check at multi-hundred-kHz frequencies. ## Dual-channel, high-side or low-side configuration Two independent driver channels with non-inverting input support high-side or low-side driven configuration, making the TDA21490AUMA1 suitable for synchronous buck converters, half-bridge stages, and dual-phase power stages without external level shifting. The N-channel MOSFET gate type means the driver sources current to turn on the external FET and sinks current to turn it off, with the 90 A / 70 A peak rating ensuring fast rise and fall times even with high gate charge loads. The compact footprint suits dense power supply layouts where multiple phases share a small board area, but the thermal pad requires a via array to the inner ground plane to keep junction temperature below 125°C under continuous 90 A peaks.","metaTitle":"Infineon TDA21490AUMA1 OptiMOS Power Stage","metaDescription":"Infineon TDA21490AUMA1 OptiMOS™ power stage driver, 90A peak source / 70A sink, 4.25-16V supply, -40 to 125°C, active production, PG-IQFN-39 package.","metaKeywords":null},"attributes":{"series":"OptiMOS™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"OptiMOS™","Package":"Tape & Reel (TR); Cut Tape (CT)","Gate Type":"N-Channel MOSFET","Input Type":"Non-Inverting","Channel Type":"Independent","Mounting Type":"Surface Mount","Package / Case":"39-PowerVFQFN","lifecycle_stage":"eol_hot","Voltage - Supply":"4.25V ~ 16V","Number of Drivers":"2","Driven Configuration":"High-Side or Low-Side","Operating Temperature":"-40°C ~ 125°C (TJ)","Supplier Device Package":"PG-IQFN-39","Current - Peak Output (Source, Sink)":"90A, 70A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.95","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.95000","currency":"USD"},{"qty":10,"price":"$6.24000","currency":"USD"},{"qty":25,"price":"$5.89960","currency":"USD"},{"qty":100,"price":"$5.11290","currency":"USD"},{"qty":250,"price":"$4.85072","currency":"USD"},{"qty":500,"price":"$4.35252","currency":"USD"},{"qty":1000,"price":"$3.99000","currency":"USD"},{"qty":5000,"price":"$3.99000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2ba201a88cf997b7f2422a9980c80ed4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the peak output current of TDA21490AUMA1?","answer":"The TDA21490AUMA1 delivers 90 A peak source current and 70 A peak sink current, making it suitable for driving high-gate-charge MOSFETs in high-current voltage regulator modules."},{"question":"What supply voltage range does TDA21490AUMA1 support?","answer":"The supply voltage range is 4.25 V to 16 V, covering standard 5 V and 12 V gate drive rails commonly used in automotive and industrial power stages."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/TDA21490AUMA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/TDA21490AUMA1 when reusing this data.
