Original Press Release:

New Smart Gate Driver Photocoupler from Toshiba Features Improved Desaturation Sensing Function

Offers Protection from Overcurrent Conditions

Toshiba America Electronic Components, Inc. (TAEC)* has introduced a new, highly integrated, 4.0A output current smart gate driver photocoupler. Designed for use in driving medium-power IGBTs and power MOSFETs, the TLP5214A improves upon the desaturation sensing characteristics of current offerings[1]. By suppressing short-time pulse noise during switching and desaturation sensing, the TLP5214A contributes to safer operation.

Toshiba's TLP5214A comes in a wide creepage distance SO16L package. It incorporates smart features, such as desaturation leading edge blanking time, desaturation filter time, and optimization of soft turn-off performance. The TLP5214A brings high-current, high-speed output control and provides output fault status feedback, making it suitable for applications including industrial inverters, solar energy inverters, servo amplifiers, and air conditioner inverters. It also contributes to a reduction of system costs and board space while improving overall power efficiency and reliability in these applications.

"The latest Gartner market report recognizes Toshiba as the leading manufacturer of optocouplers by sales in 2015 and 2016, with 23 percent of sale-based market share in 2016[2]," noted Joseph Tso, manager of optoelectronics of TAEC's discrete business unit. "By adding the TLP5214A to our lineup, we are reinforcing our already strong position in the worldwide photocoupler market."
