Product details

USB power switch with status flag and fixed current limiting

The Texas Instruments LM3525MX-H/NOPB is a single-channel high-side P-channel USB power switch in an 8-SOIC package. It delivers up to 500 mA from a 2.7 V to 5.5 V load supply, with a typical on-resistance of 80 mOhm. The switch is controlled by a non-inverting On/Off interface and includes a status flag output for fault reporting. Built-in fault protection covers fixed current limiting, over-temperature shutdown, and under-voltage lockout (UVLO). The part operates over -40°C to 85°C, suiting it for industrial and consumer USB port power control, hub controllers, and hot-swap power distribution.

Fault protection set — no external current-sense needed

Fixed current limiting protects the upstream supply and connector from a hard short on the USB port.

Lifecycle and sourcing

No last-time-buy or obsolescence notice is in effect, so it can be specified into new designs without near-term LTB risk.

Frequently asked questions

Does LM3525MX-H/NOPB have overcurrent protection?

Yes, it includes fixed current limiting as part of its fault protection set, along with over-temperature shutdown and under-voltage lockout.
