The 40 ns maximum propagation delay and 6.5 ns maximum pulse-width distortion keep dead-time budgets tight for switching frequencies into the hundreds of kilohertz. Rise and fall times of 8 ns and 9 ns respectively reduce switching losses in IGBTs and SiC MOSFETs. ## Asymmetric drive — why 1.5 A source and 2.5 A sink matter The 1.5 A peak source current and 2.5 A peak sink current are not symmetric by accident. Many IGBT and SiC FET designs need a stronger pull-down to discharge the gate capacitance quickly during turn-off, reducing the Miller plateau duration and shoot-through risk. The UCC21541DW's sink-heavy drive matches that requirement without an external gate resistor split. If the load requires balanced source/sink, the 2.5 A sink channel can be paralleled with the 1.5 A source channel through a series resistor to equalise the gate charge profile. ## Common-mode transient immunity — 100 V/ns for noisy environments A minimum common-mode transient immunity of 100 V/ns ensures the output state does not glitch when the ground reference between primary and secondary bounces during hard-switching events. In a motor-drive or inverter stage where the switching node swings hundreds of volts in tens of nanoseconds, this rating is the margin that prevents false turn-on commands from reaching the power switch.","metaTitle":"UCC21541DW 5.7 kV Isolated Gate Driver, 1.5/2.5 A","metaDescription":"Texas Instruments UCC21541DW dual-channel isolated gate driver with 5700Vrms isolation, 1.5A/2.5A peak output, 40 ns propagation delay, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Package":"Tube","Technology":"Capacitive Coupling","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","Approval Agency":"CQC, UL, VDE","lifecycle_stage":"eol_hot","Number of Channels":"2","Voltage - Isolation":"5700Vrms","Current - Peak Output":"1.5A, 2.5A","Operating Temperature":"-40°C ~ 125°C","Rise / Fall Time (Typ)":"8ns, 9ns","Supplier Device Package":"16-SOIC","Voltage - Output Supply":"9.2V ~ 18V","Pulse Width Distortion (Max)":"6.5ns","Propagation Delay tpLH / tpHL (Max)":"40ns, 40ns","Common Mode Transient Immunity (Min)":"100V/ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.05","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.05000","currency":"USD"},{"qty":10,"price":"$3.63500","currency":"USD"},{"qty":25,"price":"$3.43600","currency":"USD"},{"qty":100,"price":"$2.97790","currency":"USD"},{"qty":250,"price":"$2.82516","currency":"USD"},{"qty":500,"price":"$2.53502","currency":"USD"},{"qty":1000,"price":"$2.13797","currency":"USD"},{"qty":2500,"price":"$2.03107","currency":"USD"},{"qty":5000,"price":"$1.95471","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/807c83aca19cd9c164a344947bcdce7c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the UCC21541DW equivalents?","answer":"Within the same TI isolated gate driver family, the UCC21520 and UCC21530 offer similar pinouts and isolation ratings but differ in output drive strength and channel configuration. The UCC21541DW is distinguished by its 1.5 A source / 2.5 A sink asymmetric drive and 5700Vrms isolation in a 16-SOIC package.
