Toshiba analogue output photocoupler targets EVs

Toshiba TLX9309 analogue output IC photocoupler

An analogue output IC photocoupler from Toshiba Electronics enables high-speed communications in automotive applications, especially electric and hybrid electric vehicles.

The TLX9309 consists of a high-output GaAlAs LED that is optically coupled to a high-speed detector. The detector consists of a photodiode and a transistor integrated on one chip. A Faraday shield has been integrated onto the photodetector chip to provide enhanced levels of common-mode transient immunity, typically up to 15kV/μs, an important parameter in electrically noisy automotive environments.
