At full load the voltage drop is about 150 mV, which keeps the power dissipation under 225 mW before the exposed pad of the 6-WSON (2x2 mm) package sinks the heat.
Adjustable current limit and fault protection
A key feature is the adjustable current-limiting threshold — the designer sets the trip point with an external resistor, which allows the same PCB layout to serve loads from a few hundred milliamps up to the 1.5 A ceiling. The part also integrates over-temperature shutdown and under-voltage lockout (UVLO), so a shorted load or a sagging supply rail trips the switch cleanly without external supervisory circuitry. A status flag output reports fault conditions to the system controller.
Package and footprint — 6-WSON with exposed pad
The switch comes in a 6-WDFN exposed-pad package (supplier device package 6-WSON, 2x2 mm). The small footprint suits dense layouts, but the pad area limits heat sinking; at 1.5 A continuous the board copper area and airflow set the practical derating.
