Its characteristics and specifications are subject to change without notice. Si88x4x Q UAD D IGITAL I SOLATORS WITH DC-DC C ONVERTER Features Applications Safety Approval (Pending) Description The Si88xx integrates Silicon Labs’ proven digital isolator technology with an on-chip isolated dc-dc converter that provides regulated output voltages of 3.3 or 5.0 V (or >5 V with external components) at peak output power levels of up to 5 W. These devices provide up to four digital channels. The dc-dc converter has user-adjustable frequency for minimizing emissions, a soft-start function for safety, a shut-down option and loop compensation. The device requires only minimal passive components and a miniature transformer. The ultra-low-power digital isolation channels offer substantial data rate, propagation delay, size and reliability advantages over legacy isolation technologies. Data rates up to 100 Mbps max are supported, and all devices achieve propagation delays of only 23 ns max. Ordering options include a choice of dc-dc converter features, isolation channel configurations and a fail- safe mode. All products are certified by UL, CSA, VDE, and CQC. High-speed isolators with integrated dc-dc converter Fully-integrated secondary sensing feedback-controlled converter with dithering for low EMI dc-dc converter peak efficiency of 83% with external power switch Up to 5 W isolated power with external power switch Options include dc-dc shutdown, frequency control, and soft start Standard Voltage Conversion 3/5 V to isolated 3/5 V 24 V to isolated 3/5 V supported Precise timing on digital isolators 0–100 Mbps 18 ns typical prop delay Highly-reliable: 100 year lifetime High electromagnetic immunity and ultra-low emissions RoHS compliant packages SOIC-20 wide body SOIC-24 wide body Isolation of up to 5000 Vrms High transient immunity of 100 kV/µs (typical) AEC-Q100 qualified Wide temp range –40 to +125 °C Industrial automation systems Hybrid electric and electric vehicles Isolated power supplies Inverters Data acquisition Motor control PLCs, distributed control systems UL 1577 recognized Up to 5000 Vrms for 1 minute CSA component notice 5A approval VDE certification conformity VDE 0884-10 CQC certification approval GB4943.1 Patents pending Ordering Information: See page 38.
