ACPL-782T Automotive Isolation Amplifier 2 with R Coupler Isolation Data Sheet Lead (Pb) Free RoHS 6 fully compliant RoHS 6 fully compliant options available -xxxE denotes a lead-free product Description Features 2% Gain Tolerance 25C The ACPL-782T isolation amplifier was designed for voltage and current sensing in electronic motor drives 15 kV/ s Common-Mode Rejection at V = 1000V CM and battery system monitoring. In a typical implementa- 30ppm/C Gain Drift vs. Temperature tion, and motor currents flow through an external resistor 0.3 mV Input Oset ff Voltage and the resulting analog voltage drop is sensed by the 100 kHz Bandwidth ACPL-782T. A differential output voltage is created on the 0.004% Nonlinearity other side of the ACPL-782T optical isolation barrier. This Compact, Auto-Insertable Standard 8-pin DIP Package differential output voltage is proportional to the motor current and can be converted to a single-ended signal Worldwide Safety Approval: by using an op-amp as shown in the recommended ap- UL 1577 (3750 V /1 min.) and RMS plication circuit. Since common-mode voltage swings CSA of several hundred volts in tens of nanoseconds are IEC 60747-5-5, DIN EN 60747-5-2(VDE 0884 Teil 2) common in modern switching inverter motor drives, the Qualified to AEC-Q100 Test Guidelines ACPL-782T was designed to ignore very high common- Automotive Operating Temperature -40 to 125C mode transient slew rates (of at least 10 kV/ s). Advanced Sigma-Delta ( ) A/D Converter Technology The high CMR capability of the ACPL-782T isolation Fully Differential Circuit Topology amplifier provides the precision and stability needed to ac- Applications curately monitor motor current and DC rail voltage in high noise motor control environments, providing for smoother Automotive Motor Inverter Current/Voltage Sensing control (less torque ripple) in various types of motor control Automotive AC/DC and DC/DC converter Current/ applications. Voltage sensing The product can also be used for general analog signal Automotive Battery ECU isolation applications requiring high accuracy, stability, Automotive Motor Phase Current Sensing and linearity under similarly severe noise conditions. The Isolation Interface for Temperature Sensing ACPL-782T utilizes sigma delta ( ) analog-to-digital General Purpose Current Sensing and Monitoring converter technology, chopper stabilized amplifiers, and a fully differential circuit topology.
