The LKS32TW279FLN2K6Q8C is a highly integrated motor drive IC, which integrates 32-bit Cortex-M0 core, a 100V DC-DC synchronous rectification buck module and a 200V three-phrase full-bridge bootstrap gate drive module in a QFN 4*4 package. It has an industrial-grade operating temperature range of -40℃ to 105℃. The switching frequency of the Buck module can be set by external resistors, with a range of 00KHz to 800KHz. It has a wide input voltage range of 5.5V ~ 80V (100V max). The pre-drive module has a built-in zero-crossing detection voltage divider resistor, reducing peripheral components.
The LKS32TW279FLN2K6Q8C can be applied in AI servers, cooling fans of communication system and water pump. Due to its high integration, simple control circuit and small product size, The chip is suitable for 4cm 48V/54V server cooling fans. The components can be completely placed on the “donut” PCB with an outer diameter of 25mm and an inner diameter of 11mm. The pre-drive source/sink drive current is 1A, with strong MOSFET driving capability, which can be used in high-power equipment (>500W).
