Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched a high voltage transistor output automotive photocoupler, “ TLX9188,” for isolated signal communication in automotive equipment, including electric mobility vehicles. Volume shipments start today.

TLX9188’s high voltage photo transistor delivers a collector-emitter voltage rating of 200V, 2.5 times higher than Toshiba’s current TLX9185A, a first for the company[1]. By specifying maximum values for switching characteristics (turn-on time, turn-off time), the new photocoupler can be used as a unidirectional switch. It can also be used in feedback circuits of analog signals in 100V to 200V equipment, helping to reduce the cost of application circuits.

Applications
Automotive equipment

  • Battery Management Systems: voltage monitoring, mechanical relay sticking detection, ground fault detection, etc.
  • Feedback of analog signals, etc.

Features
