Automotive high-side load switch with dual 4 A channels
Each of the two outputs delivers up to 4 A continuous, with a typical on-resistance of 16 mOhm. It includes a load-discharge feature to quickly discharge output capacitance when disabled.
The 14-WSON package (supplier device package 14-WSON 3x2) is a compact, thermally enhanced footprint designed for power-dissipating loads.
There is no NRND or last-time-buy notice associated with this part.
What the 16 mOhm Rds(on) means for your BOM
A typical on-resistance of 16 mOhm at 4 A translates to roughly 64 mW of conduction loss per channel at full load. That is low enough to avoid significant thermal derating in most automotive loads — think lighting modules, infotainment subsystems, or sensor power rails — as long as the PCB layout provides adequate copper area under the WSON thermal pad. The 0.8 V minimum load voltage also lets this switch handle modern low-voltage core rails without dropout issues.
