Designed for board mount applications, this component operates within a voltage range of 4 VDC to 72 VDC and features a maximum supply current of 12 uA. It utilizes a DFN-10 surface-mount package with dimensions of 3 mm x 3 mm and a height of 0.75 mm. The device supports an operating temperature range from -40°C to +85°C and includes a shutdown function. It is classified as a surge suppressor within the PMIC category.

Surge Suppression ICS Feature Summary

• Provides overvoltage protection by clamping the external N-channel MOSFET gate voltage during transient events such as automotive load dump.
• Integrates adjustable current limit functionality using an internal multiplier that generates a TMR pin current proportional to VDS and ID.
• Features fixed gate clamp voltages selectable for 12V or 24V/28V systems, ensuring safe output voltage limitation.

Surge Suppression ICS Applications

• Automotive electronics protection against high-voltage transients
• Avionics power distribution systems requiring surge suppression
• Industrial equipment safeguarding against overvoltage conditions

Surge Suppression ICS Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity upon receipt, as the DFN-10 form factor requires careful handling. Check datasheet revisions for any updates regarding thermal performance or electrical characteristics. Ensure compatibility with external MOSFET selection for optimal clamping performance. Validate storage conditions to maintain moisture sensitivity levels before soldering.

Surge Suppression ICS Selection Notes

Select this component when system design requires ultra-low standby current consumption alongside robust transient protection. Ideal for battery-powered or energy-efficient applications where quiescent loss must be minimized. Choose based on the specific voltage clamp requirement for 12V or 24V/28V architectures. Consider the DFN-10 footprint constraints for PCB layout optimization. Evaluate thermal dissipation capabilities relative to the expected surge energy levels in the target application environment.
