IR2101S SOIC-8 Gate Driver - Self-Oscillating Half-Bridge Driver IC [SMD]

IR2101S SOIC-8 High-Voltage Half-Bridge Gate Driver IC (SMD)

The IR2101S SOIC-8 is a robust high-voltage, high-speed gate driver IC. It's designed for power MOSFET and IGBT applications, enabling efficient half-bridge configurations. Built with proprietary HVIC and latch-immune CMOS technologies, it ensures ruggedized monolithic construction. This driver offers reliable operation with logic input compatible with standard CMOS or LSTTL outputs, supporting voltages down to 3.3V. Its output drivers minimize cross-conduction with a high pulse current buffer stage. A floating channel allows driving N-channel power MOSFETs or IGBTs in high-side configurations. It operates effectively from 10V up to 600V. This makes the IR2101S ideal for demanding power management and motor control systems.
