The shift-register topology means the serial data line daisy-chains across multiple devices — a single MCU SPI port controls an arbitrary number of channels without multiplying the GPIO count. Internal switches handle the current regulation per channel, so no external ballast resistors are needed for the constant-current sink. ## 24-VQFN package and thermal path The 12 outputs at 60 mA each dissipate up to roughly 720 mW total — the pad-to-board thermal path is the derating limiter, not the silicon itself. Surface-mount assembly with a standard lead-free reflow profile; the exposed pad requires a solder paste stencil aperture covering at least 50% of the pad area to avoid voids under the die attach.","metaTitle":"TLC5971RGER LED Driver IC, 12-Ch 60mA Linear, 24-VQFN","metaDescription":"Texas Instruments TLC5971RGER linear LED driver IC, 12 outputs at 60 mA per channel, shift register topology, 24-VQFN package, active production, RoHS3","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Linear","Package":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Shift Register","Mounting Type":"Surface Mount","Package / Case":"24-VFQFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Output":"17V","Number of Outputs":"12","Internal Switch(s)":"Yes","Operating Temperature":"-40°C ~ 85°C (TA)","Voltage - Supply (Max)":"5.5V","Voltage - Supply (Min)":"3V","Supplier Device Package":"24-VQFN (4x4)","Current - Output / Channel":"60mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.4","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.40000","currency":"USD"},{"qty":10,"price":"$3.05800","currency":"USD"},{"qty":25,"price":"$2.89080","currency":"USD"},{"qty":100,"price":"$2.50520","currency":"USD"},{"qty":250,"price":"$2.37672","currency":"USD"},{"qty":500,"price":"$2.13264","currency":"USD"},{"qty":1000,"price":"$1.81800","currency":"USD"},{"qty":3000,"price":"$1.81800","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/cf305f38386bbc906f077cffb96bf100.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional alternative to the TLC5971RGER?","answer":"The TLC5940RHBR is the closest peer: it also uses a shift-register topology and internal switches, but offers 16 outputs at 120 mA per channel — four more channels and double the per-channel current. The TLC5971RGER's 12 outputs at 60 mA are a better fit for lower-power indicator or signage strings where the extra headroom of the TLC5940 is not needed. The TLC69611RTWR is a constant-current linear driver with 16 outputs and PWM dimming, but it lacks internal switches — external FETs are required for each channel."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TLC5971RGER","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TLC5971RGER when reusing this data.
