TLX9188
TOSHIBA Photocoupler IRLED & Photo-Transistor TLX9188
〇 Signal transmission between different circuit potential
〇 HEV (Hybrid Electric Vehicle) and
EV (Electric Vehicle) Applications
○ Battery management System (BMS) Unit: mm 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 Pin Configuration
