Photocouplers GaAв„“As Infrared LED & Photo IC TLX9310
1. Applications Automotive Battery Management System (BMS) 2. General
The Toshiba TLX9310 consists of a high-output GaAв„“As light-emitting diode coupled with a high-speed photodiode-transistor chip. It is housed in the SO6 package. This photocoupler guarantees operation at up to 125 оЂЊ
and on supplies from 2.7 V to 5.5 V. Since TLX9310 has guaranteed 0.3 mA low supply current (IDDL/IDDH), and
1.0 mA (Topr = 105 оЂЊ) low threshold input current(IFHL), it contributes to energy saving of devices. It can drive
directly from a microcomputer for a low input current. 3. Features
