Optically isolated modulator measures motor phase currents

Nuremberg, Germany—Avago Technologies has developed an optically isolated sigma-delta modulator that uses an external clock to provide direct measurement of motor phase currents in power inverters.

Based on an advanced low power CMOS process, the ACPL-796J uses an external clock that allows synchronized data conversion between the current sensor and controller to help motor control designers eliminate complex design processes in data and clock reading. Moreover, the ACPL-796J is designed with digital inputs and outputs that are compatible with systems powered by 5- or 3-volt supplies and works under a wide industrial temperature range.

Pricing: $6 each in 10,000-unit quantities.
