The TOSHIBA TLX9309 mini-flat photocoupler is suitable for surface-mount
assembly.
The TLX9309 consists of a high-output light emitting diode optically coupled
to a high-speed detector, which consists of a photodiode and a transistor
integrated on a single chip.
Faraday shield integrated on the photodetector chip provides an enhanced
common-mode transient immunity.
The TLX9309 guarantees minimum and maximum propagation
delay time, propagation delay difference between tpHL and tpLH, and high
common-mode transient immunity.
Therefore, the TLX9309 is suitable for isolation
interface between an IPM (intelligent power module) and a control IC
circuit in motor control applications.
