Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix designation to confirm the latch-off behavior, as the -02 variant differs from auto-restart models. Ensure the 10-VFDFN exposed pad package matches the target PCB footprint. Confirm the 23V rating aligns with system voltage requirements. Check that the 3.5A current handling meets load specifications. Validate the -40°C to 125°C junction temperature range against environmental conditions.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a compact solution with integrated reverse current blocking and programmable current limits is required. The latch-off feature suits applications where manual intervention or external control is needed after a fault. Consider the 36 mΩ on-resistance for efficiency calculations. The 3mm x 3mm package offers space savings compared to larger alternatives. Ensure the 23V withstand voltage exceeds peak line transients.
