SI82C70ACC-IS

Isolators - Gate Drivers Overview

The SI82C70ACC-IS is a single-channel isolated gate driver from the Skyworks SI82Cx series, housed in an 8-SOIC package. It provides 3.75 kVrms isolation using capacitive coupling technology and delivers a peak output current of 4 A. The device operates with a supply voltage range of 3 V to 20 V on both sides and supports CMOS logic inputs. Key electrical parameters include a maximum propagation delay of 43.3 ns, rise time of 17 ns, and fall time of 18 ns. It functions within a temperature range of -40°C to +125°C and includes a shutdown feature.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IS' corresponds to tube packaging when ordering, as the 'ISR' variant indicates reel packaging. Confirm that the 3.75 kVrms isolation rating meets the safety requirements of your target application. Ensure compatibility with the 8-SOIC footprint during PCB layout. Check for moisture sensitivity level (MSL) handling requirements prior to assembly.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel driver with moderate speed and high peak current is required. Compare against the SI82C50ACC-IS if identical performance but different packaging is needed. Consider the SI82A28ACC-IS for lower current applications requiring faster switching speeds. Verify that the 43.3 ns propagation delay aligns with the timing constraints of the controlled power devices.

Isolators - Gate Drivers Part Context

This part belongs to the SI82Cx family of isolated gate drivers, which utilize Skyworks' proprietary capacitive isolation technology. The family offers various channel counts and isolation voltages. The SI82C70ACC-IS specifically targets applications needing robust 4-Amp drive with standard isolation levels, bridging the gap between low-power and high-power industrial solutions.

Isolators - Gate Drivers Replacement Considerations
