The ACS713 is an isolated DC current measuring chip. They are available in SO8 packages and current ranges from 5A to 30A in this package. Also available in AC models.
The TLP250 is an opto isolated gate driver. It features 8mA LED drive current while the driver can be supplied from 20V. This chip is suitable for driving high speed switching apps, I tested the switching up to 1MHz.
The TOSHIBA TLP590B consists of an aluminum galium arsenide infrared emitting diode optically coupled to a series connected photodiode array in a six lead plastic DIP package.
