Smart Gate Driver Photocoupler with Improved Desaturation Sensing

Toshiba Electronics Europe today announced the launch of a new smart gate driver photocoupler (TLP5214A) for driving medium power IGBTs and power MOSFETs. The TLP5214A is intended for multiple applications where MOSFETs and IGBTs are used including industrial inverters, solar energy inverters, air conditioner inverters and servo amplifiers.

The TLP5214A integrates such features as desaturation leading edge blanking time, filtering time, and optimization of soft turn-off performance. These contribute to secure execution of applications by suppressing short-time pulse noise during switching and desaturation sensing.

Improving on the performance of the TLP5214, the new device boasts a DESAT leading edge blanking time of 1.1μs (typ.) and a DESAT filter time of 90ns (typ.). The soft turn-off time of 7μs is double that of its predecessor.

The TLP5214A operates from a 15 to 30V supply and is able to deliver a peak output current of ±4.0A (maximum). The short propagation delay of 150ns (with ±80ns skew) supports use in high-speed applications.

TLP5214A is housed in a SO16L package with a maximum height of 2.3mm, which meets the requirements of all major safety standards. Its isolation voltage is 5000Vrms and the minimum creepage / clearance distance is 8.0mm.

The TLP5214A is already shipping in mass production quantities.
