Smart Gate Driver Photocoupler with 2.5 A Output Current Whose Output Type is Widely Used in Industrial Equipment

Product News 2022-05

Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched a 2.5 A output smart gate driver photocoupler, TLP5212, that protects power devices from over-current which may be generated in circuits such as inverters that use medium-capacity IGBTs or power MOSFETs.

The new product has changed its output type from the current products[1] to meet specifications widely used in applications such as industrial equipment. In addition, the product has incorporated protection functions such as IGBT desaturation detection, active Miller clamp, and FAULT output, allowing the reduction of external circuits. This helps reduce the system costs for fault detection and protective operation. In addition, by incorporating Toshiba’s own highly reliable and high output power infrared LED, it can be used in a wide range of applications, including home photovoltaic power systems and industrial equipment such as UPSs[2] used in severe thermal environments.
With its propagation delay time and propagation delay skew specified at the operating temperature rating (Ta =-40 °C to 110 °C), this product allows easier design.
Its package, SO16L, is slim with a maximum height of 2.3 mm, helping improve the freedom in the layout of parts on a system board. In addition, it features a minimum creepage distance of 8 mm, allowing it to be used for applications requiring high insulation performance.

TLP5212 resumes stand-by mode from protective action by input side LED signal. TLP5222[3], which resumes to stand-by mode automatically after specified time, is under planning for mass production.
