Farnell stocking smart gate drivers from Toshiba

Farnell is now shipping the new-to-market smart gate driver photocouplers from Toshiba. Available for fast delivery, the new photocoupler range includes the TLP5212 and TLP5222 devices which are suitable for a wide range of applications including inverter circuits used in industrial control equipment, power conditions in solar power systems and UPS, and residential home battery systems.

The advanced features of the new devices enable design engineers to benefit from increased space and system cost savings.

TheTLP5212 and TLP5222 devices include various functions including V_CE,_(sat) or V_DS,_(sat)  detection, Miller clamping and a 'fault' outputting function along with a general-purpose gate driver coupler to protect the IGBT from overcurrent generated in the inverter stage.

The Miller clamping function suppresses gate potential rise and IGBT malfunction by bypassing the Miller current generated when the IGBT is turned off to ground. The TLP5212 requires an input-side signal to resume from shutdown protection while the TLP5222 resumes automatically after a specified time. All of this high-performance technology is packed into a low profile 16 pin SO16L package with an operating temperature of −40°C to +110°C.
