Newark now stocking new-to-market smart gate drivers from Toshiba

13 October 2022

Newark, an Avnet company and global distributor of electronic components, products and solutions, 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 uninterruptible power supplies (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.

The TLP5212 and TLP5222 devices includes various functions including collector-emitter voltage (VCE), (sat) or drain-source voltage (VDS), (sat) detection, Miller clamping and a “fault” outputting function along with a general-purpose gate driver coupler to protect the insulated-gate bipolar transistor (IGBT) from overcurrent generated in the inverter stage. The Miller clamping function suppresses gate potential rise and IGBTSource: NewarkSource: Newark 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.

Other key features of Toshiba’s new-to-market smart gate drivers now available for fast delivery from Newark include:

  • The TLP5212 is a ±2.5 A output photocoupler able to control IGBTs and metal oxide semiconductor field-effect transistors (MOSFETs), reliably protecting power devices from over-current and are suitable for high-speed applications requiring high levels of safety isolation and insulation (BVs = 5,000 Vrms). The SO16L package features 8 mm creepage for use in space-limited applications.
  • The TLP5222 is a highly integrated and multi-functional high current, high-speed output control photocoupler providing ±2.5 A output current. Housed in a long creepage and clearance SO16L package, it includes desaturation detection, isolated FAULT status feedback, soft gate turn-off and active Miller clamp, under voltage lockout (UVLO) and automatic FAULT status reset.
