DESCRIPTION

· The Si85xx products are unidirectional AC current sensors with full-scale ranges of 5, 10, and 20 A.

· They offer size, performance, and cost advantages over older current-sensing technologies.

· These sensors feature extremely low-loss, adding less than 1.3 mΩ of series resistance and less than 2 nH series inductance at 25°C.

· Current-sensing terminals are isolated from other package pins, providing up to 5 kV RMS isolation.

FEATURES

· Single-chip AC current sensor with low loss.

· Leading-edge noise suppression eliminates the need for leading-edge blanking.

· "Ping-Pong" output version allows one Si85xx to replace two current transformers in full-bridge designs.

· Available in 5, 10, and 20 A full-scale versions with ±5% initial accuracy.

· Input frequency range from 50 kHz to 1 MHz.

· FAULT output for safeguarding operation.

· Large 2 VPP min output at full scale.

· Suitable for high-side or low-side current sensing.

· Compact 4x4x1 mm QFN package with 1 kV RMS isolation.

· 20-pin wide-body SOIC with 5 kV RMS isolation.

· Operating range from -40 to 125°C.

· UL/VDE/CSA approval.
