SI8232BB-D-ISR

Isolators - Gate Drivers Overview

The SI8232BB-D-ISR is a dual-channel galvanically isolated gate driver from the Si823x series, manufactured by Skyworks Solutions. It features capacitive coupling technology with a 2500 Vrms isolation voltage and an 8 V undervoltage lockout (UVLO). The device operates within a supply voltage range of 9.4 V to 24 V and supports peak output currents of 2 A and 4 A for high-side and low-side channels, respectively. It exhibits a maximum propagation delay of 60 ns and rise/fall times of 12 ns. The component is housed in a 16-SOIC package, rated for operation between -40°C and +125°C, and holds AEC-Q100 qualification.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation via silicon-based capacitive coupling technology
• Features independent high-side and low-side drive channels with distinct current capabilities
• Includes undervoltage lockout (UVLO) functionality for reliable operation
• Offers high electromagnetic immunity and fast switching characteristics

Isolators - Gate Drivers Applications

• Motor drive and control systems
• Industrial power management circuits
• Inverter and converter topologies

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'ISR' confirms tape-and-reel packaging rather than tube. Confirm the 'BB' variant corresponds to the 2.5 kVrms isolation rating and 8 V UVLO threshold as documented. Ensure compatibility with the 16-SOIC footprint and check for AEC-Q100 automotive grade requirements if applicable to the target design.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated driver with 2.5 kVrms isolation is required. The 8 V UVLO setting suits applications where lower turn-on thresholds are beneficial. Compare against the SI8232BD variant if higher 5 kVrms isolation is needed. Consider the SI8233 series if higher peak output currents or different isolation ratings are necessary for the specific load requirements.

Isolators - Gate Drivers Part Context

This part belongs to the Si823x family of isolated gate drivers, which utilize Skyworks' proprietary silicon isolation technology. The family offers various isolation voltages and UVLO options to suit diverse industrial and automotive applications. The SI8232BB-D-ISR specifically addresses needs for moderate isolation strength with precise UVLO control in a compact surface-mount package.

Isolators - Gate Drivers Replacement Considerations

SI8232BD-D-ISR provides similar functionality but with 5 kVrms isolation and 5 V UVLO. SI8233BB-D-ISR offers higher peak output currents (4A/4A) while maintaining 2.5 kVrms isolation.
