It delivers a peak output current of 3A source and 3A sink, making it suited for medium-power DC-DC converters, motor drive inverter stages, and class-D audio amplifiers where the bootstrap supply can reach up to 118 V. The supply range of 9 V to 14 V aligns with standard industrial bias rails, and the junction temperature rating of -40°C to 125°C covers both outdoor telecom enclosures and under-hood automotive environments when the thermal profile allows. ## Switching speed and dead-time planning Typical rise time of 430 ns and fall time of 260 ns. The 3A peak drive provides gate charge delivery for larger-die MOSFETs. ## Package and mounting notes Housed in an 8-PowerSOIC package (0.154\" body width, 3.90 mm) with an exposed PowerPad on the underside. The PowerPad must be soldered to a suitable copper plane on the PCB for thermal relief. ## Lifecycle and sourcing posture The part is available through independent distribution channels and is sourced to order against an RFQ.","metaTitle":"LM5100AMRX/NOPB Gate Driver, 3A Half-Bridge, 118V Bootstrap","metaDescription":"TI LM5100AMRX/NOPB is a 3A peak half-bridge gate driver for N-Channel MOSFETs, 9V-14V supply, 118V bootstrap, -40 to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Bulk","Gate Type":"N-Channel MOSFET","Input Type":"Non-Inverting","Channel Type":"Independent","Mounting Type":"Surface Mount","Package / Case":"8-PowerSOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"9V ~ 14V","Number of Drivers":"2","Driven Configuration":"Half-Bridge","Operating Temperature":"-40°C ~ 125°C (TJ)","Rise / Fall Time (Typ)":"430ns, 260ns","Supplier Device Package":"8-SO PowerPad","Logic Voltage - VIL, VIH":"2.3V, -","High Side Voltage - Max (Bootstrap)":"118 V","Current - Peak Output (Source, Sink)":"3A, 3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.96","stockQuantity":0,"priceTiers":[{"qty":154,"price":"$1.96000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8f297946ba9ff453a3ce5598d7cd149e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional alternative to the LM5100AMRX/NOPB?","answer":"The LM5106MM/NOPB is a synchronous-channel half-bridge driver with faster rise/fall times (15 ns, 10 ns) but lower peak output current (1.2 A).
