1 / 37 page Preliminary Rev. 0.4 6/12 Copyright © 2012 by Silicon Laboratories Si85xx This information applies to a product under development. Its characteristics and specifications are subject to change without notice. Si85xx Si85 XX U NIDIRECTIONAL AC C URRENT S ENSORS Features Applications Description The Si85xx products are unidirectional ac current sensors available in full-scale ranges of 5, 10, and 20 A. Si85xx products are ideal upgrades for older current- sensing technologies offering size, performance, and cost advantages over current transformers, Hall effect devices, DCR circuits, and other approaches. The Si85xx are extremely low-loss, adding less than 1.3 m of series resistance and less than 2 nH series inductance in the sensing path at 25 °C. Current-sensing terminals are isolated from the other package pins, providing up to 5 kVRMS isolation level per safety approval ratings. Safety Approval (20-Pin SOIC Only) Functional Block Diagram Single-chip ac current sensor Low loss: <1.3 m primary series resistance and <2 nH inductance Leading-edge noise suppression eliminates need for leading-edge blanking "Ping-Pong" output version allows one Si85xx to replace two current transformers in full-bridge designs 5, 10, and 20 A full-scale versions ±5% initial accuracy 50 kHz to 1 MHz input frequency range FAULT output to safeguard operation Large 2 VPP min output at full scale High-side or low-side current sensing Compact 4x4x1 mm QFN package (1 kVRMS isolation) 20-pin wide-body SOIC (5 kVRMS isolation) –40 to 125 °C operating range UL/VDE/CSA approval Power supplies Motor controls Lighting equipment Industrial equipment UL 1577 recognized 5000 VRMS for 1 minute CSA component notice 5A approval IEC 60950, 61010, 60601 approved VDE certification conformity IEC 60747-5-2 (VDE0884 Part 2) Typical Application VDD VOUT IIN IOUT L C Q1 Q2 PH1 PH2 R1 OUT VDD1 GND2 VIN Si850x TRST R2 Si851x VDD TRST/FAULT IOUT IIN GND INTEGRATOR SIGNAL CONDITIONING ADC AUTO CALIBRATION LOGIC TEMP SENSOR OUT1 OUT2 MODE LOGIC MODE R1 R2 R3 R4 RESET LOGIC GND1 Patents pending Ordering Information: See page 26.
