C780A - Brand New TOS Full, Half-Bridge Drivers
-
Description
The ACPL-C78A/C780/C784 family of isolation amplifers is designed for current sensing in electronic motor drives. In a typical implementation, motor currents flow through an external resistor and the resulting analog voltage drop is sensed by the ACPL-C78A/C780/C784. A differential output voltage is created on the other side of the ACPL-C78A/C780/C784 optical isolation barrier. This differential output voltage is proportional to the motor current and can be converted to a single-ended signal by using an op-amp as shown in the recommended ap plication circuit. Since common-mode voltage swings of several hundred volts in tens of nanoseconds are common in modern switching inverter motor drives, the ACPL-C78A/C780/C784 is designed to ignore very high common-mode transient slew rates (of at least 10 kV/μs).
