Photocoupler with low power consumption

Toshiba’s has launched the TLX9310, a low power consumption photocoupler housed in a 5pin SO6 package for high-speed communication in automotive applications.

Integration of a high-power infrared LED and high-gain/high-speed integrated circuit photo IC chip cuts power consumption to below a quarter that of Toshiba’s current output type ICs (TLX9304, TLX9376, TLX9378) and will reduce consumption during standby and driving of automotive applications.

The latest Gartner market report recognises Toshiba as the leading manufacturer of photocouplers by sales in 2015 and 2016, with 23 per cent of sale-based market share in CY2016.

Applications include:

  • Automotive Battery Management (BMS) for signal communication
  • For signal communication of other automotive application equipment

Features include:

  • Operating temperature -40 to 105oC; Storage temperature -55 to 125oC
  • Threshold input current: 1.0mA (max) @IO=-3.2mA, VO>2.4V
  • High-level/low-level supply current: 0.3mA (max) @IF=0mA/2mA
  • Propagation delay time (max): 250ns (max) @VIN=3.3V, RT=820Ω
  • Propagation delay skew (device to device) (max): 65ns @VIN=3.3V, RT=820Ω
  • Totem pole output
