Magnachip Introduces TOLT-Packaged 80V MXT MV MOSFET for E-Scooters and LEVs
- Significant Improvements in Thermal Management and Power Efficiency for Motor Control Systems in E-Scooters and Light Electric Vehicles (LEVs) SEOUL, South Korea, July 28, 2025--(BUSINESS WIRE)--Magnachip Semiconductor Corporation ("Magnachip" or "Company") (NYSE: MX) today announced the release of a new 80V MXT MV MOSFET, MDLT080N017RH, featuring a TOLT (TO-Leaded Top-Side Cooling) package. The Company has already begun supplying the new MOSFET to a leading global electric motor manufacturer. The TOLT-packaged MOSFET delivers a major advancement in thermal management. Unlike conventional TOLL (TO-Leadless) packages that dissipate heat through the bottom, the TOLT package is engineered to release heat directly from the top via a mounted metal heat sink. This innovative structure substantially reduces thermal resistance between the junction and the external environment, making it well-suited for thermally demanding applications, such as e-scooters and LEVs. Simulations and tests conducted by Magnachip demonstrated that our new 80V MV TOLT package solution achieved an average 22% reduction in junction temperature compared to using standard TOLL packages. This improvement not only extends an application's lifespan, but also enhances the system reliability. Furthermore, the TOLT package enables compact, lightweight application designs thanks to its high power density and efficient thermal flow that does not compromise current-handling capability and thermal safety margins. "This new 80V MXT MV MOSFET, equipped with the TOLT package, is a testament to Magnachip's advanced capabilities in high-performance and energy-efficient power semiconductors," said YJ Kim, CEO of Magnachip. "We remain committed to delivering next-generation solutions that address evolving customer needs to strengthen our position in the global power market." Magnachip's New TOLT-Packaged 80V MXT MV MOSFET Product MDLT080N017RH Rated Voltage 80V RDS(on) 1.7 mΩ (Max., VGS=10V) Package TOLT (TO-Leaded Top-Side Cooling) Applications E-scooters, LEVs, e-bikes, personal mobility devices, high-efficiency DC motor drives, battery management systems, power distribution systems, and more.

Slkor® SL27517A: Drop-in Replacement for TI UCC27517 with Enhanced 4A Symmetric Drive
Slkor's SL27517A reduces BOM cost by 30% vs. TI UCC27517 while extending voltage range to 20V for battery-critical applications. 1.1 Product Name: SLKOR SL27517A MOSFET Driver Solution 1.2 Applications: Power tools, motor control, AC/DC converters, industrial control, etc. 2. Performance Benchmarking & Strong Compatibility 2.1 Symmetrical Drive Capability The SLKOR SL27517A, a 4A single-channel gate driver, offers significant advantages when replacing TI's UCC27517DBVR. Key benefits include performance compatibility, cost control, design flexibility, and supply stability. The SL27517A provides 4A peak sink/source current (symmetric drive) at VDD=12V, identical to the UCC27517's 4A source/sink capability. It efficiently drives power devices like MOSFETs and IGBTs, making it ideal for switching power supplies and DC-DC converters. 2.2 Wide Voltage Range The SL27517A operates from 4.5V to 20V, outperforming the UCC27517 (4.5V-18V), especially enhancing adaptability in low-voltage or battery-powered applications (e.g., portable devices). 2.3 Low Delay & High-Speed Response The SL27517A features short propagation delay (typ. 12ns) and fast rise/fall times (6ns/11ns), minimizing switching losses. This suits high-frequency applications like digital power supplies and GaN device driving. 3. Design Flexibility & Enhanced Safety 3.1 Dual-Input Configuration & Power Consumption The SL27517A supports inverting (IN-) or non-inverting (IN+) input modes. Its dual-pin design flexibly adapts to different logic control requirements, simplifying circuit design. 3.2 Floating Input Protection When inputs are floating, the SL27517A output automatically latches low, preventing false triggering of power devices and enhancing system reliability. 3.3 Low Quiescent Current Minimal static current makes it ideal for battery-powered or low-power scenarios (e.g., solar equipment, UPS). 4. Typical Application of SLKOR SL27517A in High-Power Driving Scenarios Application Principle: 4.1 The input modulation signal provides a PWM waveform to drive the SLKOR PC817 optocoupler U2. At 24V pulse high level, the optocoupler current is ~6mA (adjustable via current-limiting resistors R6/R8 for 5V control). U2 primarily provides signal isolation. Optocoupler power is supplied by the SLKOR LM2596S-5.0 DC-DC power management IC (5V output). External modulation signals can originate from a PLC. D1 (SLKOR switching diode) acts as a freewheeling diode, conducting to protect optocoupler U2 during signal reversal. U1 is the SLKOR SL27517A gate driver IC—a single-channel 4A high-speed low-side gate driver. It efficiently and safely drives MOSFETs/IGBTs. Features like low propagation delay, compact SOT-23 package, and ultra-low quiescent current enable MOSFET switching frequencies up to several hundred kHz. This chip is ideal for synchronous rectification drives in server/communication power supplies and industrial applications. 4.2 Engineering Recommendations: ● SL27517A is powered by 12V in this circuit. When pin 5 outputs high, it drives the SLKOR SL142N06Q MOSFET to activate the load. ● The SL142N06Q MOSFET provides a typical drain-source current of 20A at Vgs=10V, with a low 2.6mΩ on-resistance (Rds(on)), making it excellent for high-speed switching and synchronous rectification. ● Select R3 value based on actual PCB layout (100Ω shown). Place R3 close to the MOSFET gate with short traces to minimize parasitic inductance. ● D3 (switching diode) accelerates MOSFET turn-off; add as needed. 5. SLKOR SL27517A Gate Driver DEMO Board ● Double-layer PCB design. When driving parallel SL142N06Q MOSFETs handling high current, the DEMO board uses extended power copper pours on both sides for heat dissipation and current capacity. ● CN2/CN1: Connect to motor/laser pump. ● CN2/CN3: Connect to power supply (12V-60V max). ● SL27517A's low delay enables widespread use in PWM-driven high-power MOSFET applications. ● Features SLKOR logo; scan QR code to follow SLKOR updates. 6.
