TLP350 / TLP350S — High-Speed Optocoupler Gate Driver IC
The TLP350 (DIP-8) and TLP350S (SOP-8) are high-speed optocoupler gate driver ICs from Toshiba, designed for driving IGBTs and power MOSFETs with full galvanic isolation. With a ±1.5A peak output current, ultra-fast 100ns propagation delay, and a wide supply voltage range, the TLP350 is ideal for high-frequency inverters, motor drives, and switching power supplies.
