TLX9188 consists of phototransistors optically coupled to an infrared LED.
TLX9188 is housed in the very small and thin SO6(4pin) package and that
guarantees high temperature operation(Ta=125 °C max). With the high
breakdown voltage between the collector and emitter (VCEO=200 V), TLX9188
is suitable for use in battery management system.

 Collector-emitter voltage: 200 V (min)
 Current transfer ratio: 50% (min) to 600%(max)
Rank GB: 100% (min) to 600%(max)
 Isolation voltage: 3750 Vrms (min)
 Operating temperature: -40 to 125 °C
 AEC-Q101 qualified
