Si88x2x Data Sheet  
Dual Digital Isolators with DC-DC Converter  
KEY FEATURES  
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 pro-  
vide up to two digital channels. The dc-dc converter has user-adjustable frequency for  
minimizing emissions, a soft-start function for safety, a shutdown option and loop com-  
pensation. The device requires only minimal passive components and a miniature trans-  
former.  
• 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  
The ultra-low-power digital isolation channels offer substantial data rate, propagation de-  
lay, 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.  
• 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  
• 3/5 V to isolated 24 V  
• 24 V to isolated 24 V  
Applications:  
• Precise timing on digital isolators  
• 0 – 100 Mbps  
• Industrial automation systems  
• Hybrid electric and electric vehicles  
• Isolated power supplies  
• Inverters  
• Data acquisition  
• Motor control  
• 18 ns typical prop delay  
• PLCs, distributed control systems  
• Highly-reliable: 100 year lifetime  
• High electromagnetic immunity and ultra-  
low emissions  
• RoHS compliant packages  
• SOIC-20 wide body  
Safety Approval (Pending):  
• SOIC-16 wide body  
• UL 1577 recognized  
• VDE certification conformity  
• VDE0884-10  
• Isolation of up to 5000 Vrms  
• Up to 5000 Vrms for 1 minute  
• CSA component notice 5A approval  
• IEC 60950  
• High transient immunity of 100 kV/µs  
(typical)  
• CQC certification approval  
• GB4943.1  
• AEC-Q100 qualified  
• Wide temp range  
• –40 to +125 °C
